Why you should do it: Exfoliating provides all the same benefits for your hair and scalp as it does for your face. It can help remove any product build up at your roots from hair spray, gels, and pomades that can weigh hair down. The extra stimulation can help increase circulation, which can increase hair growth. And if you have dandruff, a quick scalp scrub can help eliminate flakes.
How you can do it: You can mix up a simple scalp scrub using brown sugar and olive oil. In order to make sure the product gets to your roots, part the scalp into four or more sections then apply at the parted areas. Massage gently in circular motions. Then shampoo and condition normally. You can also get a chemical exfoliation with a product such as Keune Careline Derma Exfoliating Treatment ($15.75). Either way, a happier scalp is just a shampoo away.
