Dandruff is a common scalp condition characterized by flaking and, sometimes, mild itchiness. It can be due to several factors, including dry skin, sensitivity to hair products (contact dermatitis), oily skin associated with seborrheic dermatitis, or the overgrowth of a yeast-like fungus called Malassezia. Dandruff isn't contagious or serious, but it can be embarrassing and sometimes difficult to treat.
