What causes cradle cap?

It's not clear what causes cradle cap, although it 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 their birth. These hormones may make the baby's glands produce more sebum.

Cradle cap isn't contagious and it isn't caused by poor hygiene or an allergy . It doesn't mean the baby isn't being looked after properly or has an infection.

Babies with cradle cap may be more likely to develop dandruff , which is another type of seborrhoeic dermatitis, when they're older.
