Cradle cap on light skin
Cradle cap is characterized by scaly patches on a baby's scalp. You may notice thick, yellow patches of skin. The patches may be crusty or greasy.
Cradle cap on dark skin
Cradle cap appears as patchy scaling or thick crusts on the scalp and greasy skin covered with flaky white or yellow scales. Cradle cap usually doesn't bother the infant.
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 weeks or a few months. Home care measures include washing your baby's scalp daily with a mild shampoo. This can help you 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.

When to see a doctor
See your baby's doctor if:
- You've tried treating it at home without success
- The patches spread to your baby's face or body
The cause of cradle cap isn't known. One contributing factor may be hormones that pass from the mother to the baby before birth. These hormones can cause too much production of oil (sebum) in the oil glands and hair follicles.
Another factor may be a yeast (fungus) called malassezia (mal-uh-SEE-zhuh) that grows in the sebum along with bacteria. Antifungal treatments, such as ketoconazole, are often effective, supporting the idea that yeast is a contributing factor.
Cradle cap isn't contagious, and it's not caused by poor hygiene.
Shampooing your baby's hair every few days can help prevent cradle cap. Stick with a mild baby shampoo unless your baby's doctor recommends something stronger.
