Every girl wants smooth facial skin, but you may not realize that a smooth scalp is important, too. As dead scalp skin cells slough off, they may flake and cause dandruff or clog hair follicles. An exfoliating massage will remove the dead cells as well as improve circulation. Forget making an appointment for a costly hair treatment, though -- you can exfoliate your scalp yourself in the comfort of your own home if the skin issues are caused by dandruff or clogged follicles and not a medical condition. An all-natural, homemade exfoliator is your ticket to a smoother scalp.
