Turns out, marine clay can be very beneficial for hair and scalp in the same way it can be beneficial for the rest of the body: it removes toxins to leave hair clean while calming the scalp. Marine Clay Stimulating Shampoo features a unique, two-in-one formula that combines a shampoo and scalp mask to purify the scalp and regulate oil production. It gently cleanses and increases scalp microcirculation, encouraging the growth of stronger, thicker, and healthier hair. Hair is left light, the scalp is relaxed, and with regular use, the need for frequent shampooing is reduced.
