Crusty, oily, scaly patches on baby's head or face are called cradle cap. About half of all babies get it in their first few months. The condition, caused by overactive oil glands under the hair and skin, doesn't itch, but it doesn't look pretty, either. The solution is to wash baby's head with mild baby shampoo every few days. You can also rub in a little baby oil, then brush or wash it off. Go easy on baby's soft spot, but rest assured that his little head can handle gentle cleaning.
