When cradle cap appears on a part of the body other than the scalp, it is known as seborrhoeic dermatitis.
What causes cradle cap?
The cause of cradle cap is not clear, but may be linked to overactive sebaceous glands.
These are glands in the skin that produce an oily substance called sebum.
Some babies are thought to retain some of their mother's hormones in their bodies for several weeks or months after the birth. These hormones may make the baby's glands more active and produce more sebum.
The excess sebum causes old skin cells to stick to the scalp, instead of drying up and falling off as they would normally do.
Cradle cap is not contagious and not caused by a lack of cleanliness. If a baby has cradle cap, it does not mean they have an infection or that they are not being looked after properly.
It is thought that a child with cradle cap may be more likely to have other types of seborrhoeic dermatitis, such as, when they are older.
How to treat cradle cap
Cradle cap requires no specific treatment and usually clears up on its own after a number of weeks or months.
However, gently washing your baby's hair and scalp with baby shampoo may help prevent a build-up of flakes.
Gently massaging a small amount of baby oil or natural oil, such as almond or olive oil, into the scalp at night can help to soften and loosen the scales. In the morning use a soft baby brush or cloth to gently remove any loose particles and then wash the hair with a baby shampoo.
You could also try washing their hair more frequently than usual (up to once a day) and brushing the scalp using a soft brush to remove any loose flakes.
It's important not to pick at the scales because it may cause an infection.
If regularly washing your baby's hair has not helped, shampoos to help loosen cradle cap are available over the counter at pharmacies. Check the patient information leaflet before using these for any ingredients your child is allergic to and follow the instructions carefully.

Shampoos that contain groundnut oil or peanut oil should be avoided in children under five years of age.
