Washing the baby's hair with mild shampoo daily and brushing the scalp with a soft-bristle brush help treat cradle cap, according to Mayo Clinic. Petroleum jelly or mineral oil rubbed gently into the scalp several minutes before washing and brushing helps loosen stubborn scales.
Cradle cap often clears up on its own and doesn't harm the baby, notes WebMD. Mild home treatments help speed up the process of clearing the oil and skin cells caused by the condition. Gentle massage of the scalp may work to loosen the scales instead of brushing. A fine-tooth comb is another option, as long as the teeth don't scratch or irritate the baby's scalp. Doctors can prescribe special shampoos, but these shampoos can cause irritation.
