The same way you exfoliate your face and body, exfoliating your scalp is an absolute must for proper hair care. Hair health starts at the root, and product or oil buildup will only weaken your hair follicles over time. Keep in mind that if you have skin sensitivities like eczema, psoriasis, or acne on your scalp, an abrasive exfoliant like a scalp scrub might not be for you. But if you don’t have any of these concerns, you’re totally good to go. Trust me when I say that incorporating a scalp scrub into your hair care routine at least once a week will make a drastic difference in your hair’s overall health and shininess. (And don’t we all want healthy, shiny hair?) Below, some of the best scalp scrubs you can buy right now. To buy: $38; dermstore.com. To buy: $42; sephora.com. To buy: $38; sephora.com.
