Morning,
I found this at ivillage. Hope it helps.
Parents should keep in mind that this condition is not caused by poor care or poor hygiene. In fact, the cause of this condition is not completely understood.
The sebaceous glands of the skin produce oils, and the glands are stimulated by hormones. The infant is exposed to high levels of hormones in the womb, and these hormones linger for some time after he is born. It is thought that this exposure to these hormones makes it more likely to develop cradle cap in those prone to do so.
Cradle cap will eventually go away on its own, however, there are a few things you can do to help with the baby's appearance and keep the area of involvement in check. The basic strategy is to gently loosen the scales so that they may be easily removed:
If the scales are dry, rub mineral oil into the scalp prior to washing. This will help loosen the scales
Wash your child's head with a baby shampoo daily.
Massage the scalp with a toothbrush to loosen the scales.
Brush your child's hair gently to help get rid of the scales.
For the most part, the above suggestions -- plus the tincture of time -- will allow for cradle cap to subside. Some physicians and parents have suggested rubbing mineral oil into the scalp even after shampooing the hair. And some suggest using a dandruff shampoo when the cradle cap does not seem to be getting better.
If your baby's scalp seems to be significantly irritated, your physician may prescribe hydrocortisone ointment. Be sure to contact your physician if you notice any:
Redness
Irritation
If the cradle cap extends to cover the skin of the face, neck or trunk
If the condition seems to worsen, despite your best efforts
