Caddle Cap

Cradle cap is a patchy, greasy, scaly and crusty skin rash that occurs on the scalp of recently born babies. Cradle cap is infantile seborrhoeic dermatitis that is confined to the scalp. Infantile seborrhoeic dermatitis may also affect other areas of the body such as behind the ears, in the creases of the neck, armpits and diaper area.
The cause of cradle cap is not clearly defined but it is not caused by infection, allergy or poor hygiene. Possibly it has to do with overactive sebaceous glands in the skin of newborn babies, due to the mother’s hormones still in the baby’s circulation. The glands release a greasy substance that makes old skin cells attach to the scalp as they try to dry and fall off. There may be a relationship with skin yeasts (malassezia).
No particular baby is more at risk than any other. Cradle cap is a very common condition that usually appears within the first 6 weeks of life. In some cases the condition will slowly resolve itself over a few weeks whilst in others it may continue for 6 to 9 months, and sometimes much longer.
Cradle cap is characterised by greasy, yellow scaly patches over the scalp. In some cases a thick scaly layer may cover the whole scalp. Over time the scales may become flaky and rub off easily. The condition is usually not itchy and in most cases babies are unaware of the problem.
Treatment of cradle cap is with mild baby shampoos. The scalp should be washed regularly and this along with soft brushing should help to remove the scales. Some people advocate the use of a baby oil or mineral oil (but not olive oil as this encourages proliferation of malassezia). Small amounts rubbed on the affected areas may help to soften the scales, which can then be more easily removed.
If the cradle cap doesn’t improve with frequent washing or if the rash spreads to other areas, your doctor may prescribe a medicated shampoo containing ketoconazole, and hydrocortisone cream for any inflamed or reddened areas.
Cradle cap is not a serious condition and is only temporary. It usually clears up by the time the child is six to twelve months old but may occasionally persist for longer. Seborrhoeic dermatitis may then occur again after the child reaches puberty. A different form of dermatitis, atopic dermatitis (infantile eczema), often develops as the cradle cap is improving. Atopic dermatitis generally continues for several years and is very itchy.
