Seborrheic dermatitis, also known as dandruff, is both uncomfortable and frustrating. There are a variety of causes of dandruff, but the key to solving the problem really is an effective anti-dandruff shampoo. That's because while "many people think that dandruff is a dry, scaling issue, but really, this is a greasy, flaky problem," says Amy McMichael, M.D., a professor and chair of the Department of Dermatology at Wake Forest Baptist Health in Winston-Salem, North Carolina. Swapping a shampoo-conditioner set with the bacteria-fighting ingredient like pyrithione zinc into your routine weekly can help treat dandruff by help eliminating debris and purifying the scalp.
In addition to combating flakes, using a dandruff shampoo can clear clogged hair follicles that lead to an itchy, flaky scalp and “stunt hair growth and affect its quality,” adds Doris Day, M.D., a dermatologist in New York City. While the Good Housekeeping Institute Beauty Lab hasn't formally tested anti-dandruff shampoos, GH Beauty Lab experts have a decades-long history of evaluating all types of shampoos both in the Lab using technical instruments as well as on consumer testers for ease of use, lather, scent, and look and feel of hair after use. Based on this expertise, our GH Beauty Lab scientists plus dermatologists and hairstylists weighed in to find the best shampoos for fighting dandruff based on active ingredients and efficacy.
