Seborrheic dermatitis

Seborrheic dermatitis is a common chronic or recurrent skin condition that causes red patches covered with large, greasy, flaking yellow-gray scales, and persistent itch.

Seborrheic dermatitis occurs most often on areas of the body with oil-producing (sebaceous) glands, including the scalp, face (especially on and around the nose, eyebrows, and eyelids), ears, upper chest, and back.
