dandruff

A popular term for pityriasis capitis. The condition features scaliness of the scalp from flakes of dead skin. Some loss of surface skin cells is normal, but excessive scaliness may be due to infection with the fungus Malassezia furfur that causes PITYRIASIS VERSICOLOR. Dandruff responds well to medicated shampoos, especially those containing selenium and lithium. Also known as pityriasis furfuracea.
