Whether you have a dry, itchy scalp or just want to prolong time between getting your hair dyed, finding the right cleanser for your tresses can make all the difference. Thankfully, the best sulfate-free shampoos can help you get your hair clean, without irritating your scalp or stripping away color.
You might be wondering what sulfates even are—and you’re not alone. “Sulfates refer to certain cleansing ingredients that are emulsifiers and are known to create a foaming lather when applied,” explains Marisa Garshick, M.D., F.A.A.D., board-certified dermatologist at MDCS in NYC and an assistant clinical professor of dermatology at Cornell - New York Presbyterian Medical Center. “Some people may opt for sulfate-free shampoos as they are thought to be more gentle on the scalp and hair, making them less likely to strip moisture or remove color from the hair.”
“While all shampoos are intended to cleanse the hair, shampoos that contain sulfates strip the color of the hair much more [rapidly] than a non-sulfate shampoo, as a Colourist this is extremely important,” explains Bianca Hillier, celebrity hair colorist.
According to Hillier, you’ll want to avoid parabens as much as possible, too. “Parabens and sulfates are the chemicals in most shampoos and conditioners that strip the color out of the hair,” she says. “They aggressively can cause a number of problems for your hair including drying, irritating your scalp, fading your color, and even in some cases hair loss.”
If you’re thinking of trying a sulfate-free shampoo, it’s important to note that these types of cleansers might not create as much of a lather. But Dr. Garshick says not to worry, it’s still cleaning your locks. “As sulfate-free shampoos don’t create as much of a foaming lather, they may initially not feel like you are getting as deep of a clean, but they are still effective at shampooing the scalp.”
