This is a serious problem and requires medical treatment.Cradle cap is the term used when seborrheic dermatitis affects the scalp of infants. It occurs within a week or two after birth. It is characterized by dirty, yellowish, thin or thick crusts on the top of head (vertex) with little itching and no inflammation.
