What is dandruff?

Dandruff, also called seborrheic dermatitis, is an inflammatory condition that forms on oily areas of the skin, particularly on the scalp or inside the ear. The inflammation results in flaking scales that range in color from white to yellow. In infants, this condition is called cradle cap.

Dandruff is a chronic, lifelong disorder that is usually manageable with ongoing treatment and can disappear completely between flare-ups. Although it can cause embarrassment or social stress in some cases, it is not contagious and is rarely severe.

Dandruff can be emotionally taxing in severe cases, but it is not a life-threatening condition. Left untreated, it can lead to secondary bacterial or fungal infections. Seek prompt medical care if you are being treated for dandruff and any skin patches form crusts, exude pus, or become very red or painful.
