If dandruff keeps returning no matter what supermarket shampoo promises, a medicated one is the logical next step. Antifungal shampoos containing ketoconazole target the yeast behind most dandruff and seborrhoeic dermatitis, while coal tar formulas calm scaling and itching in conditions like scalp psoriasis. Used as directed – typically a couple of times a week – most people see real improvement within two to four weeks.
