Yes, scalp scrubs are good for your hair. Scalp scrubs help improve the follicle quality and boost healthy scalp and hair. Your regular shampoo might not be effective in removing excess oil, dirt, dust, dead skin cells, and other impurities completely from your scalp. This is where a scalp or hair scrub comes to the rescue and helps thoroughly exfoliate the impurities, build-up, and pollutants from the scalp. L’Oréal Professionnel Rebalancing Scalp Scrub is a professional scalp scrub for dandruff that instantly exfoliates pollutants, and impurities from the scalp and gives you a soothing and purifying experience.
