Dandruff: Dandruff is a rash on the scalp that produces lots of flaking skin. It is not a dry scalp, and using pomades and oils may hide the scaling, but also may make it worse. Get dandruff shampoos like selsun and head and shoulders, and do a deep, lathering shampoo of her head and scalp, using each, every other day. You can also buy Hydrocortisone lotion 1% and rub it into the scalp and face.
