Health A to Z
Cradle cap is the greasy, yellow scaly patches that sometimes appear on the scalps of young babies.
It is common, harmless and doesn't usually itch or cause discomfort. Do not pick at the scales as this can cause an infection.
Cradle cap is not contagious and is not caused by poor hygiene or an allergy.
It usually appears in babies in the first two months and clears up without treatment within weeks to a few months.
Cradle cap is easy to recognise by the large, greasy, yellow or brown scales on your baby's scalp.
The scales flake and may make the affected skin look red. Sometimes the hair will come away with the flakes, but it will grow back.
It usually occurs on the scalp but can also affect the face, ears, neck, nappy area and armpits, and behind the knees.
Most cases of cradle cap clear up on their own without the need for treatment within weeks to a few months.
Tips to help reduce the build-up of scales on the scalp:

You can buy special shampoo for cradle cap from a pharmacy. Always read the instruction leaflet to check it's safe to use on your child.
Avoid getting the shampoo in your baby's eyes. If you're unsure about using it, speak to a pharmacist for advice.
If these home treatments don't lead to any improvement, your doctor may recommend an antifungal cream.
A mild steroid cream may also be recommended in some cases where the baby has a nappy rash.
