Cradle cap is a form of dermatitis affecting babies in their first few months of life. It looks like a bad case of dandruff or psoriasis - it's in fact a form of seborrhoeic dermatitis that shows up as a greasy, scaly yellow crust on the scalp. Cradle cap is not usually itchy and does not bother your child. Mild cases of cradle cap are extremely common. Cradle cap usually occurs in newborn babies. After around six months, babies grow out of cradle cap and don't seem to get it again.

The medical community doesn't actually agree on what causes cradle cap. It's not a bacterial infection, it's not an allergy and it's not a result of poor hygiene. It is an inflammatory condition, which may be a fungal infection or overactive sebaceous glands. A fungal infection may have occurred if mother or child received a dose of antibiotics just before or after birth. Antibiotics will destroy both the bad and the good bacteria - the friendly bacteria being the kind that help keep fungal infections at bay. Overactive sebaceous glands are the result of the mother's hormones remaining in the baby's body after birth. Babies in utero are surrounded by amniotic fluid and active sebaceous glands are what keep their skin waterproof. After birth, if your baby is producing too much sebum, old skin cells will stick to the scalp instead of drying and falling off.
Mild cases of cradle cap usually fixes itself within 6-12 months, so you don't really need to do anything. But there are a few things you can try to help normalise the sebaceous glands and keep fungal infections at bay.
Another theory is a deficiency in B-vitamins or Biotin. Pregnant mothers can sometimes become deficient in biotin, and supplementing nursing mothers is thought to help treat cradle cap. It's not uncommon for cradle cap to spread to the eyebrows or behind the ears, but see your doctor if the condition becomes inflamed or starts to spread to other areas of the baby's face and body or whether fungal conditions like thrush develop.
As it's not known what exactly causes cradle cap, prevention is really a best effort scenario.
