Tip: Sometimes dandruff can be caused by a buildup of natural oils and dead skin cells on the surface of the scalp, which is probably the case if you see oatmeal-sized flakes. The solution: exfoliate your scalp. Before you shampoo, treat yourself to a head massage.
"Pull yourself up to your vanity rather than holding your arms up over your head, cup your scalp with your hands, and knead in a circular motion with the ball of your fingers," said Phillips. "It's going to help any debris that's sitting on the surface of the skin get dislodged."
