Seborrheic Dermatitis

Seborrheic dermatitis, also known as seborrhea, is a common non-contagious condition of skin areas rich in oil glands (the face, scalp, and upper trunk). Seborrheic dermatitis is marked by flaking (overproduction of skin cells) and sometimes redness and itching (inflammation) of the skin, and it varies in severity from mild dandruff of the scalp to scaly, red patches on the skin.
