Seborrheic (seb-o-REE-ik) dermatitis is a common skin condition that mainly affects your scalp. It causes scaly patches, red skin and stubborn dandruff. Seborrheic dermatitis can also affect oily areas of the body, such as the face, upper chest and back.

Seborrheic dermatitis doesn't affect your overall health, but it can be uncomfortable and cause embarrassment. It isn't contagious, and it's not a sign of poor personal hygiene.

Seborrheic dermatitis is usually a long-term condition. You may need many repeated treatments before the symptoms go away. And they may return later. You may be able to manage flare-ups by recognizing seborrheic dermatitis symptoms and using a combination of self-care steps and medications.

Seborrheic dermatitis is also called dandruff, seborrheic eczema and seborrheic psoriasis. For infants, it's known as cradle cap.
