The Scalp Serum is made to support hair growth. This daily quick-dry, water-light serum is infused with five percent Capixyl™, clinically shown to support thicker-, fuller-, healthier-looking hair. One percent hyaluronic acid provides multi-level hydration for a dry, sensitive scalp, while vitamins B3, B5, and ApiScalp strengthen the scalp's protective barrier. The hypoallergenic, noncomedogenic, fragrance-free formula leaves no residue, is dermatologist tested, and was awarded the Seal of Acceptance by the National Eczema Association. 30 milliliters equates to a one-month supply.
