Dandruff, or seborrheic dermatitis, causes oily, scaly, flaking skin on the scalp and other areas. The condition is caused by overactive oil glands (sebaceous glands). The condition may result in yellow or white skin flakes shedding from the affected area. Although it may be unsightly and uncomfortable, dandruff is not dangerous. Treatment consists of the use of special shampoos that contain dandruff-fighting ingredients including salicylic acid, selenium sulfide, pyrithione zinc, tar, and ketoconazole.
