What's your scalp type? Pick which description best fits you, then use these tips and products to get to the root of your problems.
Oily
The Strategy
1. Shampoo and massage your scalp daily, says Marc Zollicoffer, a global educator for Aveda.
2. An oily scalp can become prone to folliculitis (breakouts) near your period. Lather up twice in the shower during that week.
3. If you have dandruff, use an anti-dandruff shampoo.

Normal
The Strategy
1. When seasons change, adjust your shampoo.
2. Try a monthly massage with pure jojoba oil to balance skin: Leave on 10 minutes, then wash.
3. If you see powdery-fine flakes but don't itch, get rid of the product buildup with a weekly clarifier.
