If a flaky scalp is bothering you, medicated shampoo may do the trick. But lifestyle changes also can help prevent dandruff.
The Mayo Clinic suggests:
* Keep stress in check.
* If your hair is oily, shampoo each day.
* Enjoy limited time in the sun. Sunlight may appear to help dandruff, but its ultraviolet light increases your risk of skin cancer. Apply sunscreen on any exposed skin.
