How to comb out cradle cap safely

Cradle cap, also called infantile seborrheic dermatitis, causes greasy or dry scales on a baby’s scalp. The skin beneath may look pink, but the condition is usually not caused by poor hygiene and is not a sign that the baby is uncomfortable. Pulling at firmly attached scales can create tiny breaks in the skin, so combing should remove only what has already loosened. Similar-looking rashes can involve the face, folds, or body and may need a different approach.

Wash your hands, then apply a small amount of a plain emollient or another clinician-recommended softener to the scalp. Leave it briefly to loosen the scale, wash it out with a mild baby shampoo, and use a soft baby brush or fine-tooth comb with light pressure. Work in the direction of hair growth and never scratch with fingernails. Do not pick at bleeding areas or leave oil sitting on the scalp for long periods. An [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) plan may help when dryness is prominent. Do not use medicated products, including [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/), unless a clinician advises it.

Contact a clinician if the scalp is very red, swollen, cracked, wet, bleeding, or covered with pus, or if the baby seems unwell or feverish. Arrange an assessment when the rash spreads widely, affects the eyes or ears, causes significant itch, or does not settle with gentle care. A clinician can distinguish cradle cap from infection, eczema, or another infant rash and choose a safe product.

Ask which softener is suitable for your baby’s age, how often to wash the scalp, and whether every scale needs to be removed. Ask what signs suggest infection, whether the rash elsewhere changes the diagnosis, and when to return if the scalp remains inflamed.
