What it looks like
Greasy yellow or white scales and crusts on the scalp, sometimes flaky and dry. Usually not itchy or bothersome to the baby.
On brown and black skin, redness may look purple, grey or darker than surrounding skin; texture (raised, rough, blistered) is often the better clue.
What causes it
Not fully understood; linked to overactive oil glands and a common skin yeast. Not caused by poor hygiene.
What helps at home
- Wash the scalp with a mild baby shampoo a few times a week.
- Gently loosen scales with a soft brush after washing. Don’t pick them.
- A little baby oil or emollient before washing can soften thick crusts. Avoid peanut and olive oil.

Questions parents ask
Is cradle cap painful?
Usually not. It looks worse than it feels. If your baby seems itchy or uncomfortable, ask your pediatrician about eczema.
