PROBLEM #2: Flaky scalp Your scalp can shed dead skin cells in large clumps (dandruff). The cause is unknown, but it may be from a yeast-like fungus on the scalp.
TREAT IT: Get a prescription lotion. Try a medicated shampoo. Besides preventing dandruff, an over-the-counter (OTC) dandruff shampoo may clear up your symptoms. If an OTC medicated dandruff shampoo doesn't help after a few weeks, see your dermatologist. "She can prescribe a steroid lotion or spray that can be rubbed into the scalp to decrease inflammation," says Dr. Berson.
PREVENT IT: Try a medicated shampoo. Use an over-the-counter shampoo containing pyrithione zinc or selenium sulfide. Let it sit in your hair for a few minutes before rinsing. Condition your hair. Follow with a conditioner that's labeled "protein-rich" to hydrate your hair. Turn off the hair dryer. The heat from the dryer can aggravate or lead to dandruff. Allow your hair to air-dry, or use a lower heat setting when you do blow-dry your hair.
