How do heat protectants for hair work? A chemistry expert explains

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Heat can do amazing things to change your hairstyle. Whether you’re using a curling wand to get ringlets, a flat iron to straighten or a hair dryer to style, it’s primarily the heat from these tools that delivers results.</p> <p>This comes with casualties. While your hair is surprisingly tolerant to heat compared with many other parts of your body, it can still only withstand so much. Heat treatment hair appliances frequently operate at over 150°C, with some reportedly <a href="https://www.frontiersin.org/journals/bioengineering-and-biotechnology/articles/10.3389/fbioe.2019.00298/full#B13">reaching</a> <a href="https://www.researchgate.net/publication/289291195_Thermal_degradation_of_hair_I_Effect_of_curling_irons">over 200°C</a>. At these temperatures, your hair can end up fried.</p> <p>Many people use heat protectants, often in the form of sprays, to minimise the damage. So how do these protectants work? To answer that, I first have to explain exactly what heat does to your tresses on the molecular level.</p> <h2>What heat does to your hair</h2> <p>A large proportion of your hair is made up of proteins. There are attractive forces between these proteins, known as hydrogen bonds. These bonds play a big role in dictating the shape of your locks.</p> <p>When you heat up your hair, the total attraction of these hydrogen bonds become weaker, allowing you to more easily re-shape your hair. Then, when it cools back down, these attractions between the proteins are re-established, helping your hair hold its new look until the proteins rediscover their normal structure.</p> <p>The cuticle – the outermost protective layer of your hair – contains overlapping layers of cells that lose integrity when they’re heated, damaging this outer protective layer.</p> <p>Inside that outer layer is the cortex, which is rich in a protein called keratin.</p> <p>Many proteins don’t <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">hold up structurally</a> after intense heating. Think of cooking an egg – the change you see is a result of the heat altering the proteins in that egg, unravelling them into different shapes and sizes.</p> <p>It’s a <a href="https://library.scconline.org/v049n04/33">similar story</a> when it comes to heating your hair. The proteins in your hair are also susceptible to heat damage, reducing the overall strength and integrity of the hair.</p> <p>Heat can also affect substances called melanin and <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">tryptophan</a> in your hair, resulting in a change in pigmentation. Heat-damaged hair is <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">harder to brush</a>.</p> <p>The damage is even more devastating if you use heat styling tools such as <a href="https://labmuffin.com/why-you-should-never-straighten-or-curl-wet-hair/">curling irons or straighteners</a> to <a href="https://library.scconline.org/v062n01/23">heat wet hair</a>, as at the high treatment temperatures, the water soaked up by the fibres can violently evaporate.</p> <p>The result of this is succinctly described by science educator and cosmetic chemist Michelle Wong, also known as <a href="https://labmuffin.com/how-do-heat-protectant-hair-products-work/">Lab Muffin</a>. She notes if you heat wet hair this way, “steam will blast through your hair’s structure”.</p> <p>This steam bubbling or bursting through the hair can <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">cause substantial damage</a>.</p> <p>It’s worth noting hair dryers don’t concentrate heat in the same way as styling tools such as flat irons or curling wands, but you still need to move the hair dryer around constantly to avoid heat building up in one spot and causing damage.</p> <p>Once heat damage is done, regardless of whether it is severe or mild, the best remaining options are symptom management or a haircut.</p> <p>For all of these reasons, when you’re planning to heat treat your hair, protection is a good idea.</p> <h2>How hair protectants work</h2> <p>When you spray on a hair protectant, many possible key ingredients can go to work.</p> <p>They can have <a href="https://library.scconline.org/v062n01/15">daunting-looking names</a> like polyvinyl pyrrolidone, methacrylates, polyquaterniums, silicones and more.</p> <p>These materials are chosen because they readily stick onto your hair, creating a coating, a bit like this:</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=225&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=225&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=225&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=283&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=283&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=283&fit=crop&dpr=3 2262w" alt="A cartoon of coating attached to a strand of hair." /></a><figcaption><span class="caption">Hair protectant applies a coating to your hair.</span> <span class="attribution"><span class="source">Author provided</span></span></figcaption></figure> <p>This coating is a protective layer;

Is stress turning my hair grey?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>When we start to go grey depends a lot on <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">genetics</a>.</p> <p>Your first grey hairs <a href="https://elifesciences.org/articles/67437">usually appear</a> anywhere between your twenties and fifties. For men, grey hairs <a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">normally</a> start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.</p> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">rapid greying</a> usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?</p> <p>You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.</p> <h2>What gives hair its colour?</h2> <p>Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of <a href="https://www.sciencedirect.com/science/article/pii/S1534580720301040">stem cells</a>:</p> <ul> <li>keratinocytes, which produce <a href="https://my.clevelandclinic.org/health/body/23204-keratin">keratin</a>, the protein that makes and regenerates hair strands</li> <li>melanocytes, which produce <a href="https://my.clevelandclinic.org/health/body/22615-melanin">melanin</a>, the pigment that colours your hair and skin.</li> </ul> <p>There are <a href="https://www.ncbi.nlm.nih.gov/books/NBK459156/">two main types</a> of melanin that <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">determine hair colour</a>. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.</p> <p>The <a href="https://theconversation.com/studying-the-complex-genetics-behind-hair-colour-reveals-how-melanin-affects-us-171088#:%7E:text=Eumelanin%20is%20also%20known%20as%20the%20brown-black%20pigment%2C,is%20due%20to%20low%20amounts%20of%20both%20pigments.">amount of the different pigments</a> determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.</p> <h2>So what makes our hair turn grey?</h2> <p>As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.</p> <p>As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.</p> <p>Unpigmented hair <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">looks grey</a>, white or silver because light reflects off the keratin, which is pale yellow.</p> <p>Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">irregular</a> as the stem cells change with age.</p> <p>Interestingly, grey hair also grows faster than pigmented hair, but it <a href="https://elifesciences.org/articles/67437">uses more energy</a> in the process.</p> <h2>Can stress turn our hair grey?</h2> <p>Yes, stress can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">cause your hair to turn grey</a>. This happens when <a href="https://faseb.onlinelibrary.wiley.com/doi/epdf/10.1096/fj.05-4039fje">oxidative stress</a> damages hair follicles and stem cells and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2022.839859/full">stops them producing</a> melanin.</p> <p>Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">caused by</a> psychological or emotional stress as well as autoimmune diseases.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">Environmental factors</a> such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.</p> <p>Melanocytes are <a href="https://elifesciences.org/articles/67437">more susceptible to damage</a> than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.</p> <p>Scientists have been able to link less pigmented sections of a hair strand to <a href="https://elifesciences.org/articles/67437">stressful events in a person’s life</a>. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.</p> <h2>4 popular ideas about grey hair – and what science says</h2> <p><strong>1. Does plucking a grey hair make more grow back in its place?</strong></p> <p>No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the <a href="https://my.clevelandclinic.org/health/body/23435-hair-follicle">root</a>. It grows from the hair follicle.</p> <p>Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.</p> <p>It’s possible frequent plucking could make your hair <a href="https://pubmed.ncbi.nlm.nih.gov/18713071/">grey earlier</a>, if the cells that produce melanin are damaged or exhausted from too much regrowth.</p> <p><strong>2. Can my hair can turn grey overnight?</strong></p> <p>Legend says Marie Antoinette’s hair went <a href="https://www.healthline.com/health/marie-antoinette-syndrome">completely white</a> the night before the French queen faced the guillotine – but this is a myth.</p> <p>Melanin in hair strands is chemically stable, meaning it can’t transform instantly.</p> <p>Acute psychological stress does rapidly deplete melanocyte stem cells <a href="https://www.nature.com/articles/s41586-020-1935-3">in mice</a>. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of <a href="https://www.medicalnewstoday.com/articles/326764">about 1 cm per month</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">Not all hair</a> is in the growing phase at any one time, meaning it can’t all go grey at the same time.</p> <p><strong>3. Will dyeing make my hair go grey faster?</strong></p> <p>This <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9953601/">depends on the dye</a>.</p> <p>Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.</p> <p>Accumulation of hydrogen peroxide and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10232955/">other hair dye chemicals</a> in the hair follicle <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">can damage</a> melanocytes and keratinocytes, which can cause greying and hair loss.</p> <p><strong>4. Is it true redheads don’t go grey?</strong></p> <p>People with red hair also lose melanin as they age, but differently to those with black or brown hair.</p> <p>This is because the red-yellow and black-brown pigments are chemically different.</p> <p>Producing the brown-black pigment eumelanin is more complex and <a href="https://onlinelibrary.wiley.com/doi/full/10.1034/j.1600-0749.2002.02017.x">takes more energy</a>, making it more susceptible to damage.</p> <p>Producing the red-yellow pigment (pheomelanin) causes <a href="https://www.sciencedirect.com/science/article/pii/S016953472030375X">less oxidative stress</a>, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.</p> <p>With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.</p> <p>Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.</p> <p>Eating <a href="https://www.healthline.com/health/melanin-in-hair#b-6-and-b-12">a healthy diet</a> may also help because vitamin B12, copper, iron, calcium and zinc all <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">influence melanin production and hair pigmentation</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/239100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate Professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to revive your curls without paying salon prices

<p>Maintaining curly hair takes a lot of time and effort and sometimes no matter what you do, the frizz just cannot be tamed. </p> <p>While getting your hair done at the salon can be a treat, having to pay salon prices to get softness, shine and definition for your curls is just not sustainable in the long run. </p> <p>Enter <a href="https://www.johnfrieda.com/en-au/home/" target="_blank" rel="noopener">John Frieda</a>'s newest Frizz Ease Miraculous Recovery range, which is now infused with repairing ceramides designed to transform frizzy and damaged hair. </p> <p>The Miraculous Recovery Repairing shampoo and conditioner are two of my personal faves, as I could feel the difference in how soft my hair felt after the first use.</p> <p>Not only are the products safe for colour-treated hair, they also made my curls more manageable and easy to style, with the effects lasting for two days, which is amazing considering how quickly my curls can go limp. </p> <p>I also loved how subtle the scent was, and found the most effective way of applying the conditioner was to comb it through my hair with a detangling brush in the shower, as it helps distribute the product evenly. </p> <p>While different curls all need slightly different care, I found the shampoo provided the perfect balance of cleaning build-up on my hair without leaving it dry or flaky. </p> <p>The star of the range was definitely the All-in-1 extra strength serum, which provided extra protection for my colour-treated and chemically treated hair. I love that you can apply this product through wet or dry hair, and it was the perfect way to revive my curls. </p> <p>The Finishing Creme was a bit too thick for my fine, curly hair, but for those with tighter curls or those looking for some extra moisture during more humid days, a light layer of the product would surely tame any flyaways or frizz. </p> <p>With most of their products retailing for around $20 it is an affordable solution to bringing life back into colour-treated and damaged curls. The product can be found in all major supermarkets and pharmacies across <a href="https://www.chemistwarehouse.com.au/shop-online/5571/john-frieda-haircare" target="_blank" rel="noopener">AU</a> and <a href="https://www.chemistwarehouse.co.nz/shop-online/5571/john-frieda-haircare" target="_blank" rel="noopener">NZ</a>. </p> <p><em>Images: Supplied</em></p> <p> </p>

Expert reveals why you shouldn’t use hotel hair dryers

<p dir="ltr">An expert has shared why you should avoid using hair dryers that are provided in hotels. </p> <p dir="ltr">Many travellers rely on these handy devices that are often found in bathroom drawers in hotels, instead of packing your own hair dryer that can often take up valuable luggage space. </p> <p dir="ltr">However, trichologist Jacqui McIntosh, who focuses on diseases related to the scalp and hair, said travellers should avoid these appliances at all costs. </p> <p dir="ltr">According to the expert, there's a high chance there are bacteria and germs lurking inside the hair dryer that have been passed between hotel guests.</p> <p dir="ltr">"Using a hairdryer riddled with bacteria and germs does pose health risks and can be detrimental to your hair health," she told <em>The Mirror</em>. </p> <p dir="ltr">McIntosh says when the microorganisms inside a hairdryer make their way onto your hair and scalp, "they can spark infections and irritations, disrupting your hair follicles and slowing down healthy growth."</p> <p dir="ltr">Even without the worry of bacteria and germs, there's a chance of dust and mould lurking inside the appliance, which she says are "troublemakers for your scalp".</p> <p dir="ltr">"Neglected hair dryers are time bombs waiting to go off. Debris buildup inside the device spells overheating, increasing the risk of singeing your hair or scalp," she explained.</p> <p dir="ltr">McIntosh also clarified that, as pointed out in a 2009 study, hairdryers are one of the handful of items that are missed by hotel cleaning staff, so next time you’re staying in a hotel, probably best to bring your own hair dryer. </p> <p dir="ltr"><em>Image credits: Shutterstock </em></p> <p> </p>

Created to unite the beauty, grooming and styling industry as a force for good, the initiative will help raise vital funds for the Look Good Feel BeIer program while giving service providers the opportunity to build their knowledge and position as part of an invaluable support system to those undergoing treatment for cancer.</p> <p>The new initiative caters to both the consumer, or the “Style Seeker”, and the expert, known as the “Style Maker”.</p> <p>Style Makers who sign up to take part in Style For Cancer will be provided with materials to help them better understand the common side effects of cancer treatment, and advice on language to use and avoid, in order to more sensitively and compassionately support their clients as they navigate diagnosis and treatment. </p> <p>The directory of participating Style Makers will be available to all Style Seekers, allowing them to choose salons and service providers who have a better understanding of what they may be experiencing if they are undergoing cancer treatment, while also knowing they are choosing a business who is consciously supporting the important work of the Look Good Feel Better program.</p> <p>General Manager of Look Good Feel Better, Carol Kavurma, shares the passion and excitement around the launch of Style For Cancer which will provide a way for the industry to feel more empowered while further connecting with their local communities.</p> <p>“Having 34 years of incredible knowledge behind us, when looking at the Australian beauty, grooming and style industries, we saw an opportunity to make salon appointments less daunting and more comfortable for those undergoing life altering treatments,” said Carol.</p> <p>“Everybody deserves to feel excited and uplifted after a trip to the hairdresser, nail salon or when sitting in the makeup chair – it’s the whole premise of the Look Good Feel Better program – and those undergoing cancer treatment are no different."</p> <p>“To help service providers – or Style Makers - feel the same excitement and confidence when working with their clients makes the Style for Cancer initiative even more important, and one we hope will be welcomed with open arms within the industry and the broader community,” she said.</p> <p>Look Good Feel Better program participant and Style Seeker, Jodie Strong, who underwent an array of cancer treatments says the physical and mental sensitivities during treatment are challenging, and while there is some support for mental recovery, the information and resources available for physical recovery are far less abundant.</p> <p>“During treatment, particularly chemo, I didn’t have the confidence to book in any services. After my active treatments were complete, while most service providers were sensitive and careful in the way they approached me and their language with me, I was usually the one to share what worked and didn’t work for me in my recovery rather than the salon or styling professional. I think that’s from a lack of awareness in the industry around this area, so as I was never quite sure what the right thing to do or not to do was,” explains Jodie.</p> </div> </div> </div> <div title="Page 2"> <div> <div> <p>“An important part of recovery from cancer is your feelings of self-worth and being able to take care of your body both mentally and physically. There are a lot of resources in the area of mental recovery, however not as much is available on the physical side of things."</p> <p>“Style For Cancer is an important initiative to bring awareness and some education to the physical side of recovery and help patients both during and post-treatment access services to help them feel more comfortable in their recovery.”</p> <p>Michael Kelly, Founder and Creatvve Director at Salon HER believes there is room for industry professionals to improve conversation and bolster skills for listening, empathising and creating a safe environment for clients trying to navigate cancer diagnosis and treatment.</p> <p>“I think language and the wholistic therapy side of the conversation could definitely improve. Not everyone has the resources to be able to hold space for another human in a very vulnerable stage of their life."</p> <p>"Style For Cancer is an obvious cause for me to be part of as I have lost family members I love to cancer, I’ve had family members recover from cancer, and I’ve supported clients who I care for deeply through some of their darkest days. It’s an initiative close to my heart.”</p> <p>Style For Cancer fundraising activities will take place in participating businesses Australia-wide during the month of August, however the Style Maker directory and registration in the initiative are available year-round.</p> <p>All funds <a href="https://donorbox.org/styleforcancerdonations" target="_blank" rel="noopener">raised</a> through the Style For Cancer initiative will directly support the Look Good Feel Better program, with each $100 raised allowing one participant to benefit from the program, free-of-charge.</p> <p><em>Image credits: Shutterstock </em></p> </div> </div> </div>

The ultimate treatment to transform your curls

<p>Every curly-haired girl knows the struggle of having to carry around multiple hair products to manage their curls. </p> <p>Anti-frizz serums, leave-in conditioners, curl cream and heat protection spray, are a few of the essentials that most curly hair girls can't live without, but what if there was a product that could do it all? </p> <p>Revlon's UniqOne Curls treatment is the perfect solution, and as someone who struggles with finding a curl treatment that doesn't leave my curls stringy or puffy, the treatment has become an essential part of my routine. </p> <p>The treatment boasts ten different benefits including:</p> <ol> <li>Deeply nourishes and repairs damaged curls</li> <li>Enhances long-lasting natural curl definition </li> <li>96H frizz control </li> <li>Elasticity and bounce </li> <li>Provides lightweight, clean hold </li> <li>Conditions and detangles</li> <li>Heat protection </li> <li>Boosts shine </li> <li>Helps prevent split ends </li> <li>Softness and manageability</li> </ol> <p>Yes, those are some big statements, but after my first use I could already see some of the benefits, especially as someone with fine, curly hair. </p> <p>I found that my hair was less frizzy and puffy and my curls were a lot more defined, even a few days after I initially applied it. I also loved the slight sweet and fruity scent that wasn't too overpowering. </p> <p>My hair was also easier to manage and style as it wasn't as tangled and despite the gel-like texture of the product, it didn't weigh down my fine hair or leave it feeling greasy. </p> <p>I found that the best way to use the product is to use it on damp hair. </p> <p>I like to pump the product onto the palm of my hand (approx. 5-12 times depending on the thickness and length of your hair) and then rubbing it in my hands, before applying it onto my hair on layered sections to ensure even distribution. </p> <p>I then detangle my hair with a wide tooth comb before scrunching my hair with my hands to ensure even curl clumps. </p> <p>I normally blow dry my hair, but it you have extra time on your hands, you can leave it to air dry. </p> <p>The product retails for $24.95 at <a href="https://www.ozhairandbeauty.com/products/revlon-professional-uniq-one-all-in-one-curls-treatment-230ml?currency=AUD&variant=40267971428424" target="_blank" rel="noopener">Oz Hair and Beauty</a> </p> <p><em>Images: Supplied</em></p>

8 mistakes that make your hair thin

<p>Despite how many products you put load it up with, hair thins with age and there is scarcely anything that you can do to completely fight nature. What you can do is go into prevention mode as early as possible. There are many simple things that we do to our hair daily that is actually causing it a lot of stress and in many cases causing it to thin.</p> <p>So rather than a trip to the hairdresser every other week or falling for flashy and expensive products on cheap advertisements, follow these 8 simple tips to avoid damaging your hair and losing what you have.</p> <p><strong>1. Hot showers</strong></p> <p>We all know that hot water can dehydrate our skin, but did you know the same rule applies to your hair? Ryan Welter, MD, a Boston-based hair transplant surgeon explains; “Not only are you washing your hair’s protecting oils down the drain, but the heat throws your scalps pores into overdrive to keep up with oil production, which can damage the root and lead to additional shedding.”</p> <p><strong>2. Using too many heat tools</strong></p> <p>Ironic, isn’t it? All that that drying and curling we do to make our hair look fabulous is actually doing it the most damage. Not everyone is a wash-and-wear kind of person, though, so if you really can’t part with your heated tools, make sure you prep your strands with a heat protection spray. Also, they may be more expensive but ceramic plated tools are ten times better for your hair. The ceramic plate has a uniform heating system that makes it impossible for it to overheat and cause damage to the hair from burning. Additionally, you’ll get a better aesthetic result.</p> <p><strong>3. Crash dieting</strong></p> <p>Your diet affects everything, so it’s no surprise it effects your hair. Under eating forces, the body to direct the little energy it has to perform essential functions –like helping your heart pump blood-so generating new hair falls by the wayside. The good news is that you can eat certain foods for positive hair health. Lean protein like fish, chicken, lentil and beans all promote growth. Hair is primarily made of protein so it will make or break your hair. You should aim for about 46 grams per day.</p> <p><strong>4. Styling when wet</strong></p> <p>Our strands are never more fragile, and prone to breakage, than when they’re saturated with H20 – this is because the protective cuticle is slightly raised. Brushing or combing locks in the shower, then following with aggressive towel-drying and prompt styling is a recipe for swift breakages. To avoid this, let your hair dry as naturally as possible when you get out of the shower and wait patiently before styling.</p> <p><strong>5. Let’s talk about the colour</strong></p> <p>If your hair is dyed, and especially if it’s bleached, you will be more prone to breakage. However, there are many ways to avoid this. If you can’t be bothered fussing with various different treatments, simply leave your conditioner on for a few minutes rather than washing straight out. This will act like a hair treatment or mask without the hefty price tag. Alternatively, Moroccan oil is naturally high in fatty acids and vitamin E, making it a good treatment for damaged hair. Use sparingly on the ends, it only takes a few minutes to apply.</p> <p><strong>6. Opting for tight hairstyles</strong></p> <p>If you wear your hair back in a tight hairstyle, like a ponytail or bun, chances are it’s contributing to your thinning hair. Pulling on the hair follicles too tightly puts tension on them, damaging them and creating scars that destroy them permanently. This can lead to alopecia, a condition that permanently weakens the follicle and makes it impossible for hair to grow again. </p> <p><strong>7. Over-shampooing</strong></p> <p>The purpose of shampooing your hair is to cleanse the hair and scalp of oil and product build up. However, there is actually such thing as over-shampooing. This can wash away your hairs natural moisture that helps your hair look healthy and dries it out. This is especially true if you’re using a shampoo that’s more tropical scented foam than nutrition for your hair. So how much should you wash it? Unfortunately, there’s no specific algorithm. See what works best for you, stick to it, and always be gentle.</p> <p><strong>8. Using the wrong brush</strong></p> <p>Something as simple as using the wrong hairbrush could be doing you a world of damage. Unfortunately, the thinner your hair, the more damage brushing in general will do. Stick to coming and wide bristle brushes as to not aggravate delicate hair cells. For slick, slightly damp hair, natural-bristle brushes are best and for those who can get away with it, stick to a comb and nothing but the comb. Just be sure to check the teeth for seams or roughness.</p> <p>Finally, always go by the golden rule; if something is going to harm your skin, it’s going to harm your hair. </p> <p><em>Image credits: Shutterstock</em></p>

7 items you should never put in your dryer

<p>There are just some items that can’t take the dryer’s heat. To avoid shrinking and more these are the ones you should never put in the dryer.</p> <p><strong>1. Bathing suits</strong></p> <p>The dryer will leave the spandex of bathing suits brittle and broken.</p> <p><strong>2. Pantyhose</strong></p> <p>The delicate material of pantyhose will shrink in the heat of the dryer and the tumbling motion can cause stockings to get tangled.</p> <p><strong>3. Rubber-backed rugs</strong></p> <p>They may be small enough to fit in your dyer but the rubber-back of these mats might crumble in the heat of the dryer.</p> <p><strong>4. Bras</strong></p> <p>The heat of the dryer can damage bra’s elasticity and shape.</p> <p><strong>5. Clothes with embellishments</strong></p> <p>Embellishments can easily snag in a dryer – and also snag other items in the process.</p> <p><strong>6. Anything that warns against dryers</strong></p> <p>Double-check the care tag of your item of clothing before chucking it in the dryer. If it warns against using the dryer, it’s for good reason. It will help your clothes look new for longer and prevent shrinking and more.</p> <p><strong>7. Running shoes</strong></p> <p>The heat can ruin the cushioning, weaken adhesive and shrink the rubber.</p> <p><em>Image credits: Getty Images </em></p>

Why scalp care is just important as washing your hair

<p dir="ltr">When it comes to our daily beauty routines, we tend to focus on what looks and feels like it needs a refresh, such as washing our hair when it looks a little greasy, or cleansing our faces after a day of wearing makeup. </p> <p dir="ltr">While our beauty, skin and hair care routines are quick to become second nature, there is one area that often gets overlooked: our scalps. </p> <p dir="ltr">When washing our hair, it is easy to focus on the products and techniques we need to get our tresses clean, while skimping on what is best for our scalp. </p> <p dir="ltr">But now, the scalp, which is often the most overlooked part of our skin, is finally being recognised as an area that needs just as much TLC as your face.</p> <p dir="ltr">Implementing scalp care as part of our beauty routines is a must, as this sensitive area can often need extra attention due to a build-up of product, delicate skin and aggressive hair washing techniques. </p> <p dir="ltr">Hair care expert Sanja Scher from Beatnik Studio has shared how important it is to care for the scalp as the foundation for hair growth and health, and how it all starts with the right products. </p> <p dir="ltr">"Revlon Professional, known for game-changing professional haircare, styling, and colour, offers a range of products dedicated to improving the scalp - and they're available to take home. By removing excess build-up, replenishing moisture, and rebalancing the scalp’s microbiome, these targeted products ensure that the microbiome, the first line of defence, can shield hair follicles from pathogens, hair damage, infections and other irritations,” she said. </p> <p dir="ltr">“And this equals healthier, stronger, more beautiful hair.”</p> <p dir="ltr">To kick start the revolution of your hair care routine to protect your scalp, Revlon Professional's launch of the Eksperience Marine Face Mist Ultra-Light Hydration is a game-changing product that effortlessly combines skin care with hair care.</p> <blockquote class="instagram-media" style="background: #FFF;

Your passport to salon-quality haircare on a budget

<p dir="ltr">There’s nothing quite like the feeling of walking out of the hairdressers to proudly show off your new cut or colour, and your hair is the softest it's ever felt. </p> <p dir="ltr">While this post-salon feeling is second to none, it's hard to recreate at home to avoid spending big bucks at your hairdressers more than you need to. </p> <p dir="ltr">And then begins the seemingly endless journey to find a shampoo and conditioner that works for your unique hair type without breaking the bank.

What is minoxidil, the anti-balding hair growth treatment? Here’s what the science says

<p><a href="https://theconversation.com/profiles/jacinta-l-johnson-1441348">Jacinta L. Johnson</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em> and <a href="https://theconversation.com/profiles/kirsten-staff-1494356">Kirsten Staff</a>, <em><a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Hair loss (also known as alopecia) often affects the scalp but can occur anywhere on the body. It’s very common and usually nothing to worry about; about <a href="https://www.sciencedirect.com/science/article/pii/S0022202X15525840">half of Australian men</a> show signs of visible baldness at age 50 and <a href="https://www.sciencedirect.com/science/article/pii/S0022202X15525840">over a quarter of Australian women</a> report hair thinning by the same age. It’s often genetic.</p> <p>But if you’ve noticed hair loss and are worried by it, see a GP or dermatologist for a diagnosis before trying any treatments. Products claiming to reverse hair loss are everywhere, but few have been scientifically tested for how well they work.</p> <p>One group of products that have actually been scientifically tested, however, are known as topical minoxidil products. These include products such as Regaine®.</p> <p>So, do they work? Here’s what the research evidence says, what you can realistically expect and what you need to know if you’re considering this treatment.</p> <h2>What is minoxidil – and does it work?</h2> <p>Topical minoxidil usually comes as a kind of foam or serum you apply to your scalp.</p> <p>It’s been approved by the <a href="https://www.tga.gov.au/">Therapeutic Goods Administration</a>, Australia’s regulatory authority for therapeutic goods, for the treatment of hereditary hair loss in males and females. Minoxidil is also available in tablet form, but this isn’t currently approved for hair loss (more on that later).</p> <p>So, is topical minoxidil effective? In short – yes, but the results vary widely from person to person, and it needs to be used consistently over several months to see results.</p> <p>Scientists don’t know exactly how minoxidil works. It may affect the different phases of the hair life cycle, thereby encouraging growth. It also <a href="https://www.tandfonline.com/doi/full/10.1080/09546634.2021.1945527?casa_token=KhIM_u0u8nwAAAAA:5njp_XE5cHhip454ycvU1p9p_t0VVzpjRu0ozDZ9YqNb04fmhmngWzYeiowZcG5UugLQkTVIzCcj7A">opens up blood vessels</a> near hair follicles.</p> <p>This increases blood flow, which in turn delivers more oxygen and nutrients to the hair.</p> <p>While minoxidil is unlikely to restore a full head of thick, lush, hair, it can slow down hair loss and can <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD007628.pub4/full?highlightAbstract=minoxidil">stimulate regrowth</a>.</p> <p>It is the over-the-counter option with the most evidence. Two strengths are available: 5% and 2%.</p> <p>An analysis of randomised controlled trials found minoxidil applied to the scalp twice a day increased the number of hairs per square centimetre by <a href="https://pubmed.ncbi.nlm.nih.gov/28396101/">eight to 15 hairs</a>, with the higher strength treatment having a slightly greater effect.</p> <h2>Can I use it for non-genetic balding?</h2> <p>There are many causes of hair loss. The main cause in both males and females is a hereditary condition called androgenic alopecia.</p> <p>Although topical minoxidil is only approved for use in Australia for androgenic alopecia, there is some evidence it can also help in other conditions that cause hair loss.</p> <p>For example, it may hasten hair regrowth in patients who have lost hair due to <a href="https://www.jaad.org/article/S0190-9622(96)90500-9/abstract">chemotherapy</a>.</p> <p>Unfortunately, minoxidil is not effective when the hair follicle is gone, like after a burn injury.</p> <p>Although small studies have found promising results using minoxidil to promote hair growth on the face (for <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/1346-8138.13312">beard</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/24471459/">eyebrow</a> enhancement), topical minoxidil products are not currently approved for this use. More research is required.</p> <h2>What else do I need to know?</h2> <p>Minoxidil won’t work well for everyone. Early in treatment you might notice a temporary increase in <a href="https://pubmed.ncbi.nlm.nih.gov/22409453/">hair shedding</a>, as it alters the hair cycle to make way for new growth. Minoxidil needs to be trialled for three to six months to determine if it’s effective.</p> <p>And as it doesn’t cure hair loss, you must <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.14624?casa_token=P-zW7kDNRs8AAAAA%3AaUgUzxU7lbwBpg1BYPajOfXFhpb_mU5g_ounZ6GtjsLLkHO_AdVQ2Kf-8zZkW80ykBj3N_sOsyn392uc">continue</a> to use it each day to maintain the effect. If you stop, you will start losing the new hair growth <a href="https://www.nps.org.au/assets/medicines/1f8127a5-2a98-4013-a7c3-a53300feb0e5-reduced.pdf">within three to four months</a>.</p> <p>Minoxidil products may not be suitable for everyone. If you have any medical conditions or take any medications, you should speak with your doctor or pharmacist before using minoxidil products.</p> <p>It has not been tested for safety in <a href="https://www.nps.org.au/assets/medicines/1f8127a5-2a98-4013-a7c3-a53300feb0e5-reduced.pdf">people under 18, over 65, or those who are pregnant</a>.</p> <p>You can read the <a href="https://www.nps.org.au/medicine-finder/regaine-for-men-regular-strength-application">consumer medicines information sheet</a> for more information about using over-the-counter minoxidil products.</p> <p>Many people do not like to use minoxidil solution or foams long-term because they need to be applied everyday day, which can be inconvenient. Or they may notice side effects, such as scalp irritation and changes to hair texture.</p> <p>Some people <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.14624?casa_token=P-zW7kDNRs8AAAAA%3AaUgUzxU7lbwBpg1BYPajOfXFhpb_mU5g_ounZ6GtjsLLkHO_AdVQ2Kf-8zZkW80ykBj3N_sOsyn392uc">tolerate the foam products better</a> than the solution, as the solution contains more of a compound called propylene glycol (which can irritate the skin).</p> <h2>What about the oral tablet form of minoxidil?</h2> <p>Minoxidil is also available on prescription as an oral tablet. While traditionally used for high blood pressure, it has also been used as a treatment for hair loss.</p> <p>In 2020, a <a href="https://www.jaad.org/article/S0190-9622(20)32109-5/abstract">systematic review</a> identified 17 studies involving 634 patients using oral minoxidil for various hair loss conditions.</p> <p>The authors found oral minoxidil was effective and generally well tolerated in healthy people who were having trouble using the topical products.</p> <p>The review noted oral minoxidil may increase hair growth over the whole body and may cause heart-related side effects in some patients. More research is required.</p> <p>In Australia, oral minoxidil is available under the trade name <a href="https://www.nps.org.au/assets/medicines/df29e16f-6464-4652-ba1f-a53300fed275.pdf">Loniten</a>®. However, it is currently only approved for use in high blood pressure.</p> <p>When people seek a prescription treatment for a non-approved purpose, this is called “off-label” prescribing. Off-label prescribing of oral minoxidil, potentially for use in alopecia, may have contributed to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10170338/">shortages</a> of Loniten® tablets in recent years. This can reduce availability of this medicine for people who need it for high blood pressure.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223736/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/jacinta-l-johnson-1441348">Jacinta L.

From straight to curly, thick to thin: here’s how hormones and chemotherapy can change

<p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>Head hair comes in many colours, shapes and sizes, and hairstyles are often an expression of personal style or cultural identity.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">Many different genes</a> determine our hair texture, thickness and colour. But some people’s hair changes around the time of puberty, pregnancy or after chemotherapy.</p> <p>So, what can cause hair to become curlier, thicker, thinner or grey?</p> <h2>Curly or straight? How hair follicle shape plays a role</h2> <p>Hair is made of <a href="https://my.clevelandclinic.org/health/body/23204-keratin">keratin</a>, a strong and insoluble protein. Each hair strand grows from its own <a href="https://www.ncbi.nlm.nih.gov/books/NBK470321/">hair follicle</a> that extends deep into the skin.</p> <p>Curly hair forms due to asymmetry of both the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6894537/">hair follicle and the keratin</a> in the hair.</p> <p>Follicles that produce <a href="https://www.medicalnewstoday.com/articles/318524">curly hair</a> are asymmetrical and curved and lie at an angle to the surface of the skin. This kinks the hair as it first grows.</p> <p>The asymmetry of the hair follicle also causes the keratin to bunch up on one side of the hair strand. This pulls parts of the hair strand closer together into a curl, which maintains the curl as the hair continues to grow.</p> <p>Follicles that are symmetrical, round and perpendicular to the skin surface produce straight hair.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=754&fit=crop&dpr=1 754w, https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=754&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/567020/original/file-20231221-29-fp0wci.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=754&fit=crop&dpr=3 2262w" alt="A diagram shows the hair follicle shape of straight, curly and coiled hair." /></a><figcaption><span class="caption">Each hair strand grows from its own hair follicle.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/diagram-hair-follicle-shape-vector-illustration-2248429145">Mosterpiece/Shutterstock</a></span></figcaption></figure> <h2>Life changes, hair changes</h2> <p>Our hair undergoes repeated cycles throughout life, with different stages of growth and loss.</p> <p>Each hair follicle contains stem cells, which multiply and <a href="https://www.frontiersin.org/articles/10.3389/fcell.2022.899095/full">grow into a hair strand</a>.</p> <p>Head hairs spend most of their time in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5905671/">the growth phase</a>, which can last for several years. This is why head hair can grow so long.</p> <p>Let’s look at the life of a single hair strand. After the growth phase is a transitional phase of about two weeks, where the hair strand stops growing. This is followed by a resting phase where the hair remains in the follicle for a few months before it <a href="https://www.healthline.com/health/stages-of-hair-growth">naturally falls out</a>.</p> <p>The hair follicle <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/exd.13347">remains in the skin</a> and the stems cells grow a new hair to repeat the cycle.</p> <p>Each hair on the scalp is replaced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4606321/#b3">every three to five years</a>.</p> <h2>Hormone changes during and after pregnancy alter the usual hair cycle</h2> <p>Many women notice their hair is <a href="https://www.medicalnewstoday.com/articles/pregnancy-hair">thicker during pregnancy</a>.</p> <p>During pregnancy, high levels of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4908443/">oestrogen, progesterone and prolactin</a> prolong the resting phase of the hair cycle. This means the hair <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">stays in the hair follicle for longer</a>, with less hair loss.</p> <p>A drop in hormones a few months after delivery causes increased hair loss. This is due to all the hairs that remained in the resting phase during pregnancy falling out in a fairly synchronised way.</p> <h2>Hair can change around puberty, pregnancy or after chemotherapy</h2> <p>This is related to the genetics of hair shape, which is an example of <a href="https://www.biologyonline.com/dictionary/incomplete-dominance">incomplete dominance</a>.</p> <p>Incomplete dominance is when there is a middle version of a trait. For hair, we have curly hair and straight hair genes. But when someone has one curly hair gene and one straight hair gene, they can have wavy hair.</p> <p>Hormonal changes that occur around <a href="https://clinicalepigeneticsjournal.biomedcentral.com/articles/10.1186/s13148-019-0780-4">puberty</a> and <a href="https://www.mdpi.com/1422-0067/23/20/12698">pregnancy</a> can affect the function of genes. This can cause the curly hair gene of someone with wavy hair to become more active. This can change their hair from wavy to curly.</p> <p>Researchers have identified that activating specific genes can change hair in pigs <a href="https://www.frontiersin.org/articles/10.3389/fgene.2023.1184015/full">from straight to curly</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5759815/">Chemotherapy</a> has very visible effects on hair. Chemotherapy kills rapidly dividing cells, <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2628766">including hair follicles</a>, which causes hair loss. Chemotherapy can also have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1988866/">genetic effects</a> that influence hair follicle shape. This can cause hair to <a href="https://www.medicalnewstoday.com/articles/chemo-curls">regrow with a different shape</a> for the first few cycles of hair regrowth.</p> <h2>Hormonal changes as we age also affect our hair</h2> <p>Throughout life, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">thyroid hormones</a> are essential for production of keratin. Low levels of thyroid hormones can cause dry and brittle hair.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/36578854/">Oestrogen and androgens</a> also regulate hair growth and loss, particularly as we age.</p> <p>Balding in males is due to <a href="https://theconversation.com/starting-to-thin-out-hair-loss-doesnt-have-to-lead-to-baldness-34984">higher levels of androgens</a>. In particular, high dihydrotestosterone (sometimes shortened to DHT), which is produced in the body from testosterone, has a role in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7269836/">male pattern baldness</a>.</p> <p>Some women experience <a href="https://theconversation.com/health-check-why-does-womens-hair-thin-out-39126">female pattern hair loss</a>.

Why does my hair turn green from the swimming pool?

<p><em><a href="https://theconversation.com/profiles/magdalena-wajrak-1432339">Magdalena Wajrak</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>If you are a blonde like me and enjoy laps in a swimming pool, you may have noticed your hair acquires a green tint after frequent swims in chlorinated water.</p> <p>This happens to both bleached and natural blondes. In fact, the green tinge happens to everyone, but it’s less visible on dark hair and those whose hair isn’t damaged by chemical treatments such as bleaching.</p> <p>But what exactly causes this green discoloration, and what can we do about it? Most of us blame the chlorine in the pool water. However, although chlorine does play a part, it is not the main culprit.</p> <h2>Which chemicals in the pool turn the hair green?</h2> <p>The element to blame for the green staining of hair is copper.</p> <p>The main source of copper is copper sulfate (CuSO₄), a compound added to swimming pools to prevent the growth of algae. <a href="https://www.sciencedirect.com/science/article/pii/S1568988320301803?via%3Dihub">Contact with algae</a> can cause skin irritation and respiratory issues, and ingesting water with algae can lead to serious gastrointestinal problems. Only a small amount (around 0.5mg per litre or 0.5 parts per million) of copper sulfate is needed to prevent algal growth.</p> <p>However, copper can also enter swimming pools through the corrosion of water pipes, so concentrations may be higher in some pools.</p> <p>Copper sulfate crystals are greenish-blue in colour. So, when hair comes into contact with copper ions – a positively charged variant of a copper atom with extra electrons – those ions get absorbed by the hair and cause the greenish hue.</p> <p>Scientists were fascinated by the green “pool hair” phenomenon as far back as the 1970s, so we actually have research data on copper being the cause.</p> <p>One very <a href="https://jamanetwork.com/journals/jamadermatology/article-abstract/538197">interesting study in 1978</a> performed experiments by immersing hair samples into water containing different concentrations of copper ions, chlorine and various pH values (neutral and basic). Their results showed hair exposed to free copper ions does turn green.</p> <p>Furthermore, when hair is oxidised (meaning electrons are removed from the hair proteins) by chlorine, it actually damages the hair, enhancing the absorption of copper ions. Hair submerged in water with chlorine but without copper ions did not turn green. Meanwhile, hair exposed to water with only copper ions and no chlorine still formed a green colour.</p> <p>Hence, chlorine by itself does not play a role in causing the green hue we see in “pool hair”, but it does exacerbate it.</p> <h2>So, how does copper get into the hair?</h2> <p><a href="https://doi.org/10.1007/978-1-4684-0943-7_24">Other research teams</a> have conducted <a href="https://doi.org/10.1071/ch9682437">more extensive studies</a>, using sophisticated instruments, such as scanning electron microscopy, to examine how exactly copper ions attach to the hair.</p> <p>Our hair is predominantly composed of protein called keratin. Keratin is classified as a “structural fibrous protein”, meaning it has an elongated, sheet-like structure.</p> <p>The keratin structure is composed of various <a href="https://chem.libretexts.org/Courses/University_of_Kentucky/UK%3A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)/Chapters/Chapter_4%3A_Structure_and_Function/4.4%3A_Functional_Groups">chemical groups</a> (types of atom groupings with similar properties), such as carboxyl groups, amino groups and disulfide groups. Copper ions have the ability to form bonds with these groups, forming a copper-keratin complex. This complex remains in the hair, causing it to appear green.</p> <p>Interestingly, the most recent study <a href="https://doi.org/10.32657/10356/142466">conducted in 2020</a>, showed copper ions mainly bind to the disulfide groups. This study also found other metal ions such as zinc, lead, chromium and mercury also bind to hair in the same way. This is very useful in <a href="https://theconversation.com/forensic-breakthrough-study-suggests-humans-can-be-identified-by-the-proteins-in-their-hair-65051">forensic analysis</a>, for example, because forensic scientists can analyse hair samples to determine if a person has been exposed to a particular metal.</p> <p>Light-coloured hair already has the most visible green discoloration, but research has shown that damaged hair, caused by bleaching, straightening, or exposure to sun, is the <a href="https://pubmed.ncbi.nlm.nih.gov/19586601/">most susceptible</a> to the binding of copper ions. This is because in damaged hair the disulfide groups have “broken bonds” (the link that holds the elements within these groups together is broken), making it easier for the copper ions to bind to the hair.</p> <h2>Can I prevent the green colour or get rid of it?</h2> <p>To prevent your hair from turning green in a swimming pool, you have two basic options. The first is a physical barrier – just wear a swim cap.</p> <p>The second option is chemical – you can pre-treat your hair with an alkaline shampoo. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0891584918310050">Studies have shown</a> under alkaline pH conditions, the copper ions won’t attach to the hair. To treat your hair before going to the pool, you can either use a shampoo with a pH higher than 7, or you can even try mixing some baking soda into your regular shampoo.</p> <p>But what can you do if your hair has already turned greenish? Well, you can try washing your hair with a shampoo designed to achieve this, typically marketed as a “chlorine removal” shampoo. These products contain a chemical called EDTA – it can bind to metal ions (such as copper) and thus will remove copper from the hair.</p> <p>You may have heard tomato sauce or ketchup is a good way to get the green out of your pool hair – potentially because the red pigments are supposed to “cancel out” the green ones. However, I’m not aware of any scientific evidence this would work.</p> <p><em>Correction: This article has been amended to clarify that alkaline shampoos have a pH higher than 7, not lower.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211736/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/magdalena-wajrak-1432339"><em>Magdalena Wajrak</em></a><em>, Senior lecturer, Chemistry, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p><em>Image </em><em>credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is dandruff? How do I get rid of it? Why does it keep coming back?

<p><em><a href="https://theconversation.com/profiles/lorraine-mackenzie-1420658">Lorraine Mackenzie</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/sean-mangion-1420661">Sean Mangion</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180"><em>University of South Australia</em></a></em></p> <p>Dandruff can be dry, like snowflakes, or greasy, with yellow clumps. <a href="https://www.ncbi.nlm.nih.gov/books/NBK551707/">Up to half</a> of all adults have had this scalp condition at one point, so you’ll no doubt know about these skin flakes and the itchiness.</p> <p>Dandruff can be <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1439-0507.2008.01624.x">embarrassing</a>. It can affect many aspects of people’s lives, such as how they socialise, how they style their hair, and what clothes they wear.</p> <p>Dandruff is not a modern problem. In fact, it has been around for millennia and was <a href="https://pubmed.ncbi.nlm.nih.gov/2181905/">described</a> by Greek physicians. We don’t know for sure whether our ancestors were as bothered by it as much as we are today. But they were interested in what causes it.</p> <h2>What causes dandruff?</h2> <p>Dandruff is mainly caused by the yeast <em><a href="https://www.cell.com/cell-host-microbe/pdf/S1931-3128(19)30106-4.pdf">Malassezia</a></em>. The yeast lives on most people’s skin, either on the surface or in the opening of the hair follicle, the structure that surrounds a hair’s root and strand.</p> <p>The yeast feeds on sebum, the natural moisturiser secreted by your sebaceous glands to stop your skin drying out. These glands are attached to every hair follicle and the hair provides a dark, sheltered micro-environment ideal for the yeast to flourish.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=520&fit=crop&dpr=1 600w, https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=520&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=520&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=653&fit=crop&dpr=1 754w, https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=653&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/536003/original/file-20230706-22-6t0yr8.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=653&fit=crop&dpr=3 2262w" alt="Diagram of skin cross-section showing hair follicle and other skin structures" /></a><figcaption><span class="caption">The yeast that causes dandruff lives on the skin surface and in the opening of the hair follicle.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/medical-education-chart-biology-hair-diagram-645657787">Shutterstock</a></span></figcaption></figure> <p>As the yeast grows, it releases molecules that irritate the skin and disrupts how the skin normally renews itself. This causes the cells to cluster together, appearing as white flakes. When there is excess sebum, this can mix with the cells and cause the dandruff to appear <a href="https://www.headandshoulders.co.in/en-in/healthy-hair-and-scalp/dandruff/yellow-dandruff">yellow</a>.</p> <p>The link between dandruff and yeast was made nearly 150 years ago. The person who first identified and described this yeast <a href="https://www.cell.com/cell-host-microbe/pdf/S1931-3128(19)30106-4.pdf">in 1874</a> was Louis-Charles Malassez (the yeast’s namesake).</p> <h2>Why do I have dandruff?</h2> <p>As <em>Malassezia</em> is found on most people, why do some people get dandruff and others don’t? This depends on a range of factors.</p> <p>These include the quality of your skin barrier. This may mean yeast can penetrate deeper if the skin is damaged in some way, for example, if it’s sunburnt. Other factors include your immunity, and external factors, such as which hair-care products you use.</p> <p>How <em>Malassezia</em> grows also depends on the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4864613/">balance</a> of other microorganisms that live on your skin, such as bacteria.</p> <h2>How do I get rid of dandruff?</h2> <p>Dandruff is mostly treated with <a href="https://www.sciencedirect.com/science/article/abs/pii/S0939641123000292?via%3Dihub">anti-fungal</a> shampoos and scalp treatments to dampen down growth of <em>Malassezia</em>. The shampoos most commonly contain the anti-fungal agent <a href="https://pubmed.ncbi.nlm.nih.gov/34575891/">zinc pyrithione</a> (ZnPT for short). Other common anti-fungals in shampoos include selenium sulfide, ketoconazole and coal tar.</p> <p>You can also treat dandruff with scalp masks and scrubs that help restore the scalp barrier, by reducing inflammation and irritation. But as these may not have any anti-fungal action, your dandruff is likely to return.</p> <p>Home remedies <a href="https://www.healthline.com/nutrition/ways-to-treat-dandruff#7.-Omega-3s">include</a> tea tree oil, coconut or other oils, and honey. There is some evidence to support their use, mostly from <a href="https://pubmed.ncbi.nlm.nih.gov/35642120/">studies</a> that show extracts from botanical ingredients can reduce growth of the yeast in the lab. But there is great variation in the quality and composition of these ingredients.</p> <p>There is also the risk of making the problem worse by providing more oils that the yeast will enjoy, causing more imbalance to the scalp micro-organisms and leading to more irritation.</p> <p>So it’s best to stick with commercial products.</p> <h2>Why does my dandruff come back?</h2> <p>Your dandruff is likely to return unless the active ingredients in your shampoo can reach the right spot, at the right concentration, for the right amount of time needed to kill the yeast.</p> <p>Our <a href="https://pubmed.ncbi.nlm.nih.gov/36842718/">research</a> focussing on zinc pyrithione-based products showed these shampoos reached the skin surface. But they less-reliably ended up in the harder-to-reach hair follicles.</p> <p>We found the zinc pythione seemed <a href="https://pubmed.ncbi.nlm.nih.gov/35631659/">to target</a> the top of the follicles rather than deep into the follicles.</p> <p>So this may explain why dandruff keeps on coming back. Your shampoo’s active ingredient may not reach the yeast that causes your dandruff.</p> <p>We don’t yet know how we can encourage existing formulations to penetrate deeper into the follicles.</p> <h2>What about future treatments?</h2> <p>We’ll likely see new formulations of dandruff shampoos and scalp treatments that better deliver the active ingredient to where it’s needed – deeper into the hair follicles.</p> <p>We can also expect new active ingredients, such as <a href="https://pubmed.ncbi.nlm.nih.gov/28766952/">carbonic anhydrase</a> enzymes. These might target how the yeast grows in a different way to current active ingredients.</p> <p>We are also beginning to see the development of creams and lotions that aim to boost the health balance of flora of the skin, much like we see with similar products for the gut. These include pre-biotics (supplements or food for skin flora) or pro-biotics (products that contain skin flora). However we have <a href="https://www.mdpi.com/2079-9284/8/3/90/htm">much to learn</a> about these types of formulations.</p> <h2>In a nutshell</h2> <p>Dandruff is annoying, treatment helps, but you may need to repeat it. Hopefully, we can develop improved shampoos that better deliver the active ingredient to where it’s needed.</p> <p>But we need to strike a balance. We don’t want to eliminate all micro-organisms from our skin.</p> <p>These are important for our immunity, including preventing more disease-causing microbes (pathogens) from moving in. They also help the skin produce antimicrobial peptides (short proteins) that protect us from pathogens.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/201082/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/lorraine-mackenzie-1420658">Lorraine Mackenzie</a>, Associate Professor, Clinical and Health Sciences, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/sean-mangion-1420661">Sean Mangion</a>, PhD Candidate, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Big hair? Bald? How much difference your hair really makes to keep you cool or warm

<p><a href="https://theconversation.com/profiles/theresa-larkin-952095">Th<em>eresa Larkin</em></a><em>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>We have <a href="https://theconversation.com/health-check-why-does-womens-hair-thin-out-39126">millions</a> of hair follicles on our body, including around 100,000 on our scalp.</p> <p>This might sound like a lot of hair, yet humans are described as “hairless”. We have evolved to be the only mammals with a relatively hairless body, but still with scalp hair.</p> <p>So how does your hair affect your body temperature when it’s hot or cold?</p> <p>Compared with other animals, our hair does not have as much influence on keeping us warm or cool as you might think.</p> <h2>Essential to our survival</h2> <p>Our brain function and body’s metabolism depend on an optimal temperature of around 37℃. Thermoregulation maintains this body temperature, even when we are exposed to a hotter or colder external temperature.</p> <p>For non-human mammals, body hair or fur plays a role in protecting against environmental cold or heat.</p> <p>For instance, a heavy fur coat helps keep a polar bear <a href="https://polarbearsinternational.org/polar-bears-changing-arctic/polar-bear-facts/adaptions-characteristics/">warm</a> in the cold. But fur also keeps an animal cool in the heat because it can <a href="https://www.jstor.org/stable/25064866">absorb or reflect</a> radiant heat.</p> <p>Scientists think this is why humans have kept hair on our heads. Our heads are exposed to the most heat from the sun, and scalp hair keeps our heads cool.</p> <p>Research published just last week <a href="https://www.pnas.org/doi/10.1073/pnas.2301760120">suggests</a> curly hair provides the best heat protection. That’s because curly hair’s thicker layer of insulation reduces the amount of sun that reaches the scalp.</p> <h2>But hair is not the only factor</h2> <p>When humans moved from living in the jungle to the savannah, they needed to walk and run long distances in the sun. This meant they needed a way to handle the increased body temperature that comes with physical activity in the heat.</p> <p>Sweating is the best way to lose heat and cool down, but the presence of hair reduces sweating and heat loss from the skin.</p> <p>So humans evolved to <a href="https://www.pnas.org/doi/10.1073/pnas.1113915108">lose body hair</a> to be better adapted to exercising in the heat. Fewer hair follicles in our skin made room for more sweat glands. This made our skin optimal for sweat evaporation – and the <a href="https://theconversation.com/want-to-keep-cool-on-hot-summer-days-heres-how-34489">heat loss</a> that goes with it – to keep us cool.</p> <h2>So what’s best in the heat?</h2> <p>You might think removing body hair or having a bald head is best for sweating and keeping cool when exercising in the heat. However, it’s not that simple.</p> <p>Removing head hair would increase the <a href="https://www.pnas.org/doi/10.1073/pnas.2301760120">amount of sun</a> that reaches your scalp. This means you would need to <a href="https://pubmed.ncbi.nlm.nih.gov/20683812/">sweat more</a> during exercise in the sun to reduce an increase in body temperature, but not by much.</p> <p>In fact, it’s the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4667044/#:%7E:text=The%20body%20hair%20is%20advantageous,heat%20removal%20during%20heat%20stress.">least hairy</a> areas of our body that have the highest sweat rates during exercise. These are our forehead, neck, feet and hands.</p> <p>So the best way to keep cool in the heat is to keep these areas uncovered (but still use sunscreen). Removing body hair will not have a large impact on your overall sweat rate.</p> <h2>How about when it’s cold?</h2> <p>Our body hair and head hair theoretically have a role in keeping us warm, but the effects are minimal.</p> <p>When we are cold, the muscles of the hair follicles on the body contract to cause the hairs to stand straight. This is an attempt to trap heat close to the body and we see this as goosebumps. However, because our body hair is so thin, this does not have a big effect in keeping us warm.</p> <p>Our head hair can prevent some heat loss from the head, but again this is limited.</p> <p>When it’s cold, heat can still be lost through the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4667044/#:%7E:text=The%20body%20hair%20is%20advantageous,heat%20removal%20during%20heat%20stress.">skin of the head</a> regardless of your hairstyle.</p> <p>The scalp also has only a very thin layer of fat compared to the rest of our skin, so our head has less insulation to protect against the cold.</p> <p>A warm hat or beanie is the only way to prevent too much heat lost from the head.</p> <h2>In a nutshell</h2> <p>Our head and body hair, or lack of it, does have a small role in how you maintain your body temperature.</p> <p>But overall, your hairstyle does not influence whether you feel warm or cool.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/201380/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Embrace grey hair with our simple healthy hair tips

<p>While in the past going grey may have been seen as a negative of the ageing process, today women are embracing this as a stamp of wisdom. And why not? It’s en vogue and can look really attractive too. Thank goodness the days of “having” to hide your natural colour are gone! But just because you’re going natural, doesn’t mean there’s no effort involved. Knowing how to care for and style your grey locks is key and can make all the difference between “stylish and sixty-plus” and “stuffy and sixty-plus”. Read on for our top tips and tricks for healthy, happy hair.</p> <p><strong>Focus on your cut</strong> – A great cut is essential for any hair colour but especially for grey hair. Chances are good that you may have been dyeing your hair in the months/years leading up to embracing grey… so a decent chop may increase the health and vitality of your locks. Speak to your hairdresser about a style that suits both your face shape and lifestyle.</p> <p><strong>Swap your shampoo</strong> – Grey hair is far more prone to breakage and can also become quite dry and coarse. Ensuring that you’re using a moisturising shampoo at every wash can help keep strands in good condition.</p> <p><strong>Condition well</strong> – If you’ve been wary of conditioner in the past due to your hair being on the oily side, now is the time to become friendly again. Conditioning with a moisturising formula is essential after every shampoo. If you’re still nervous about hair becoming oily, you can try a shampoo for “normal” hair, which will nourish without weighing hair down.</p> <p><strong>Treat yourself to an at-home treatment</strong> – Once a fortnight, treat your hair with a shampoo specifically formulated for grey hair. After washing and conditioning, apply a clear colour glaze or gloss which is designed to coat the cuticle, boosting shine and general vitality.</p> <p><strong>Take care when styling</strong> – As it’s prone to dryness and breakage, applying a thermal protectant to your hair before heat styling is a great way to prevent damage from occurring. Simply comb through hair and style as normal. It’s also a good idea to try and have a day or two off a week from using your hairdryer/hot implements to give hair a good break.</p> <p><em>Images: Getty</em></p>
