Cradle cap causes crusty or oily scaly patches on a baby's scalp. The condition isn't painful or itchy. But it can cause thick white or yellow scales that aren't easy to remove.
Cradle cap usually clears up on its own in a few months. Home-care measures include washing your baby's scalp daily with a mild shampoo. This can help loosen and remove the scales. Don't scratch cradle cap.
If cradle cap persists or seems severe, your doctor may suggest a medicated shampoo, lotion or other treatment.
