Improper care can lead to issues like itchiness and inflammation. The state of your hair can <\/span><a href=\"https:\/\/www.everydayhealth.com\/skin-and-beauty-pictures\/things-your-hair-says-about-your-health.aspx\"><span style=\"font-weight: 400;\">also offer a window<\/span><\/a><span style=\"font-weight: 400;\"> into other conditions, like anemia or thyroid disease.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To prevent certain issues and catch other signs and symptoms, you want to make sure you\u2019re caring for <a href=\"https:\/\/www.zocdoc.com\/blog\/guides\/can-you-fix-major-hair-loss\/\">your hair<\/a> to the best of your ability. That can feel like a big ask, even to someone who pays close attention to their crowning glory. One trip to the hair care aisle or a scroll down the ads on Instagram can bombard you with confusing terms and far-fetched claims. We asked <a href=\"https:\/\/www.zocdoc.com\/blog\/guides\/when-should-you-really-see-a-dermatologist\/\">doctors<\/a> to weigh in on the best shampoo for your \u2018do.\u00a0<\/span><\/p>\n<hr \/>\n<h3>Shampoo 101<\/h3>\n<p><span style=\"font-weight: 400;\">Shampoo is basically <\/span><a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/shampoo\"><span style=\"font-weight: 400;\">soap for your head<\/span><\/a><span style=\"font-weight: 400;\">. It cleanses the scalp and hair by removing unwanted oil, dirt and product buildup that water alone can\u2019t. \u201cThe scalp is an extension of the body, and in that sense, it\u2019s no different in terms of needing a cleanser,\u201d says Los Angeles dermatologist Dr. Sanusi Umar, head of the UCLA Hair and Scalp Disorder Clinic. \u201cIf no shampoo is used, then debris, bacteria and oil can build up on the scalp and hair.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But choosing a shampoo isn\u2019t easy. \u201cThe marketing claims on shampoos and other hair products are very challenging for consumers to navigate,\u201d says Dr. Erum Ilyas, a dermatologist in Philadelphia. \u201cThere\u2019s not a \u2018user manual\u2019 to understand the claims.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are, however, some blanket rules about what ingredients you should steer clear of. Experts say to avoid shampoos that contain formaldehyde, phthalates, parabens, imidazolidinyl, toluene and alcohol.\u00a0 Frequency is another parameter to understand when shopping for hair products. If you have curly hair, a daily shampooing will likely wreck your look, no matter how much you condition after.<\/span><\/p>\n<hr \/>\n<h3>Sulfate-free shampoo<\/h3>\n<p><span style=\"font-weight: 400;\">Sulfates are salts that help lift oil and other residue from hair shafts, allowing it to be rinsed out without leaving a film. Sulfates are also behind the soapy lather your shampoo creates. Many of the sulfates found in personal care products are <\/span><a href=\"https:\/\/www.ema.europa.eu\/en\/documents\/report\/background-review-sodium-laurilsulfate-used-excipient-context-revision-guideline-excipients-label_en.pdf\"><span style=\"font-weight: 400;\">derived from petroleum<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One reason you find sulfates in so many shampoos is that they\u2019re great at cleaning hair.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But on the flip side, they can clean a little too harshly, stripping hair of its natural oils and <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4458934\/\"><span style=\"font-weight: 400;\">leading to strands<\/span><\/a><span style=\"font-weight: 400;\"> that are rough, frizzy and prone to tangling. Sulfates can also<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4651417\/\"><span style=\"font-weight: 400;\"> irritate<\/span><\/a><span style=\"font-weight: 400;\"> your eyes, skin and lungs.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sulfate-free shampoos won\u2019t lather, but some experts say they\u2019re better for certain hair types.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cSulfate-free shampoos are beneficial to people who have sensitive skin, or those who have certain skin conditions, like <\/span><a href=\"https:\/\/www.zocdoc.com\/blog\/your-acne-might-actually-be-rosacea\/\"><span style=\"font-weight: 400;\">rosacea<\/span><\/a><span style=\"font-weight: 400;\">,\u201d says Dr. Anna Chacon, a Miami-based dermatologist. \u201cThey\u2019re generally milder, so they\u2019re best for color-treated hair, and also dry and frizzy hair.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some say sulfates aren\u2019t as bad as the beauty industry claims. \u201cSulfates are something everyone loves to hate,\u201d says Ilyas. \u201cThey\u2019re strong and cheap, so they\u2019re an easy thing to add to products to enhance their ability to clean. It\u2019s true that they\u2019re likely too strong for daily shampoo use, because they can leave hair feeling excessively stripped of natural oils, but they\u2019ve been mislabeled as \u2018bad.\u2019\u201d\u00a0<\/span><\/p>\n<hr \/>\n<h3>Apple cider vinegar<\/h3>\n<p><span style=\"font-weight: 400;\">Deserved or not, apple cider vinegar has achieved near-panacea status in the wellness world. When it comes to hair care, its proponents may actually be onto something. The ideal pH balance of hair is between 4 and 5, and many shampoos <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4158629\/\"><span style=\"font-weight: 400;\">have a high pH<\/span><\/a><span style=\"font-weight: 400;\">, which can increase tangling and frizz.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In theory, an acid like apple cider vinegar can bring an alkaline environment into a more neutral pH, which marketing pros might call \u201crestoring balance.\u201d What\u2019s more, ACV has <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC8369171\/\"><span style=\"font-weight: 400;\">demonstrated antimicrobial effects<\/span><\/a><span style=\"font-weight: 400;\">, which could help kill any fungus or bacteria that might be causing issues.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cApple cider vinegar does contain high acidic content and antibacterial and antifungal properties, which may be helpful for conditions like dandruff or a scalp bacterial infection,\u201d says Umar. \u201cIt also helps keep your hair in a state of acidity, which is good for hair.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, ACV contains acetic acids, <\/span><a href=\"https:\/\/www.jaad.org\/article\/S0190-9622(11)02243-2\/fulltext\"><span style=\"font-weight: 400;\">which can burn your skin<\/span><\/a><span style=\"font-weight: 400;\">, so be sure to dilute it and avoid contact with your eyes.\u00a0<\/span><\/p>\n<hr \/>\n<h3>Off-the-shelf dandruff shampoo<\/h3>\n<p><span style=\"font-weight: 400;\">Dandruff, which causes the skin of the scalp to flake, is an eyesore. It has a <\/span><a href=\"https:\/\/www.mayoclinic.org\/diseases-conditions\/dandruff\/symptoms-causes\/syc-20353850#:~:text=Dry%20skin,such%20as%20psoriasis%20and%20eczema\"><span style=\"font-weight: 400;\">number of causes<\/span><\/a><span style=\"font-weight: 400;\">, including dry skin, a yeast-like fungus and conditions like psoriasis and eczema.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Traditional dandruff shampoo can treat some dandruff caused by these conditions. These shampoos <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5788265\/\"><span style=\"font-weight: 400;\">contain antimicrobial ingredients<\/span><\/a><span style=\"font-weight: 400;\"> (ciclopirox and zinc pyrithione are biggies) to relieve itching and flaking, buildup and excess oil.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cIf you have mild dandruff, an off-the-shelf shampoo may work just fine for you,\u201d says Chacon. \u201cThese shampoos do have active ingredients, but in much lower concentrations compared to prescription-strength dandruff shampoos.\u201d<\/span><\/p>\n<hr \/>\n<h3>Prescription shampoo<\/h3>\n<p><span style=\"font-weight: 400;\">A doctor might prescribe a shampoo to<\/span> <span style=\"font-weight: 400;\">treat more serious hair and scalp conditions, such as scalp psoriasis or extreme dandruff. It may contain the same active ingredients as off-the-shelf dandruff shampoo in higher concentrations, or other active ingredients only found in prescription products. \u201cThe three main types of prescription shampoos are antifungal, anti-inflammatory, and anti-scaling shampoos,\u201d says Ilyas.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While these products are helpful for treating specific conditions, they can be damaging in the long term. \u201cDue to their powerful ingredients, which can be harsh on the hair, prescription shampoos are usually prescribed for temporary use until a patient\u2019s condition improves,\u201d says Umar.\u00a0<\/span><\/p>\n<hr \/>\n<h3>Clarifying shampoo<\/h3>\n<p><span style=\"font-weight: 400;\">As the name suggests, clarifying shampoos are formulated to clear up residue that has accumulated on the scalp. To do this, they have higher concentrations of surfactants \u2014 a soap-like substance that includes sulfates \u2014 which help provide the deepest cleanse. \u201cClarifying shampoos have a much higher surfactant content than regular shampoo, so they do a better job of cleansing hair of excess oils and product buildup,\u201d says Umar.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These shampoos can be great for getting rid of stuff that regular shampoo can\u2019t, but they should be used sparingly, Umar says, or you risk stripping the hair of too much of its essential protective oils.\u00a0<\/span><\/p>\n<hr \/>\n<h3>Shampoo for color-treated hair<\/h3>\n<p><span style=\"font-weight: 400;\">Because of the way hair dyes bond to our hair, color-treated tresses need extra gentle cleansers. Ilyas explains that hair dyes work by opening up the hair follicle and depositing the artificial pigment inside the follicle, where it then enlarges so that it\u2019s too big to come out on its own. If the pH of your hair changes, it causes the follicle to open up once again, letting the pigment out (and thus causing your color to fade). The goal of shampoo for color-treated hair, then, is to help your hair maintain its pH balance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This means that shampoos for color-treated hair are free of harsh chemicals, especially sulfates. They may also contain color-protecting ingredients, like <\/span><a href=\"https:\/\/www.researchgate.net\/publication\/5350727_UV_protection_of_artificially_coloured_hair_using_a_leave-on_formulation\"><span style=\"font-weight: 400;\">UV protection<\/span><\/a><span style=\"font-weight: 400;\">, and moisturizing ingredients that help rehydrate color-treated hair. Your hair doesn\u2019t need to be dyed to benefit from a formula like that.<\/span><\/p>\n<hr \/>\n<h1 style=\"text-align: center;\">Ready to book an appointment with a <a href=\"https:\/\/book.zocdoc.com\/get-started\/dermatologists\">dermatologist<\/a>?
