The process involves applying a specialized exfoliating product to the skin on the head, usually with gentle massage. The purpose is to remove buildup of dead skin cells, excess oil, and product residue that can accumulate over time. For example, one would apply a small amount of the product to the scalp, massage it in circular motions for a few minutes, and then rinse thoroughly.
This practice promotes a healthier scalp environment by unclogging hair follicles and stimulating blood circulation. Improved circulation can, in turn, potentially encourage hair growth and overall hair health. Historically, methods of scalp exfoliation have been practiced using natural ingredients like salt or sugar to achieve similar cleansing effects.
