Hair and Scalp Serum 3-Pack

9.0 oz / 255 g

We were tired of pricey treatments, harsh ingredients, and sticky serums—so we made something better. Hair and Scalp Serum is a clean, concentrated serum with 5% Capixyl®, a clinically studied peptide complex shown to enhance hair density over time.* No toxins, no scary side effects—just real results powered by proven ingredients like caffeine, biotin, rosemary, and saw palmetto.

This non-sticky, non-greasy serum glides on with a breezy, cooling finish that’s easy to apply and doesn’t weigh hair down.
