Here are some of our favorites. Formulated with coal tar extract, which controls itchiness and flakiness, Neutrogena T/Gel Therapeutic Shampoo can combat different scalp conditions. It tackles seborrheic dermatitis and psoriasis, the culprits behind irritated, scaly scalps, and fights off common dandruff. The gentle cleanser is safe to incorporate into your daily grooming routine and starts working after one use, slowing down the overproduction of skin cells that leads to flakes. This one-size-fits-all shampoo is designed to treat different hair textures and styles, including perms and color treated locks. It helps fight itchiness and flakes with a formula made from 1% Selenium Sulfide, a medication that targets dandruff and seborrheic dermatitis. What’s more, the shampoo contains menthol, which offers a cooling sensation for the scalp and leaves behind a refreshing, minty scent. Tough on dandruff? Check. Smells like a heavenly combination of coconut and sweet lime? Check. Gives a hydration boost? Check. Dove DermaCare Shampoo puts in all the legwork of regular dandruff shampoos, thanks to its antifungal ingredient Pyrithione Zinc, while also promising to nourish dehydrated hair for softer, healthier strands. Nizoral has a tough, fast-acting formula. The secret? The 1 percent Ketoconazole, an antifungal ingredient that fights off dandruff. Safe for chemically processed hair, Nizoral starts improving scalp health after one use and—unlike other dandruff shampoos—you only have to apply it twice a week.
