Home remedies. Your baby may have something called cradle cap or seborrheic dermatitis. This is a very common condition and is easily treated with simple remedies. Use an anti-dandruff shampoo once a day and gently massage with a soft brush or rough washcloth. If your child's scalp is very crusty, put some baby oil or olive oil on the scalp 1 hour before washing to soften the crust.
Several ways. Do not over wash. Wash only when needed with a mild soap like dove, but mostly use warm water. Use a good moisturizer like eucerin, aquaphor or cetaphil. If it continues, see your pediatrician as a low dose Hydrocortisone may be needed.
Daily washing. This is likely to be seborrheic dermatitis. They usually outgrow it. For severe cases we can use ketoconazole cream. Mild cases do do not anything apart from daily bathes. For the head putting some cream or baby oil could soften it before bathtime and gentle circular motion while bathing will help remove them. Sometimes using a soft comb can help remove it after it is softened.
