Cradle cap is usually produced from an overproduction of sebum mixed with dead skin cells. It is harmless but often unsightly.
To treat, slowly loosen the scales by massaging with baby oil but be careful not to cause the scalp to bleed. Repeat every couple of days until it is gone. Regularly rough up the area using a fine comb or washer before washing with a baby shampoo. Cradle cap may take several weeks to clear, but if you are concerned, you should consult your healthcare professional.
