Common signs and symptoms of seborrheic (seb-o-REE-ik) dermatitis include:

  • Patchy scaling or thick crusts on the scalp
  • Yellow or white scales that may attach to the hair shaft
  • Red, greasy skin covered with flaky white or yellow scales
  • Itching or soreness
  • Skin flakes or dandruff

Seborrheic dermatitis is often found on oily areas of the body, such as the face, upper chest and back. Seborrheic dermatitis can also appear on the scalp as stubborn, itchy dandruff. For infants, it's known as cradle cap.
