Patchy scaling or thick crusts on the scalp
Oily or dry skin covered with flaky white or yellow scales
Skin flakes
Possibly mild redness
 Similar scales may also be present on the ears, eyelids, nose and groin. Cradle cap is common in newborns. It usually isn't itchy. Cradle cap is the common term for infantile seborrheic dermatitis. It's sometimes confused with another skin condition, atopic dermatitis. A major difference between these conditions is that atopic dermatitis usually causes significant itching.
