Scalp Nourishing Serum is the perfect maintenance product for anyone plagued by dry scalp. We recommend that it be used as a “leave-in” scalp nourisher. With the natural hybrid safflower base, you need only a small amount, applied sparingly, to see great results. Ylang ylang and cedar extract reduces fungus and bacteria while the sunflower oil works to soothe the scalp and restore it back to good health. Scalp Nourishing Serum is 100% natural.
