Stronger Roots. Fuller Hair. At the Source.

The Blass Beauty Hair Serum is a targeted scalp treatment built around two of the most studied active ingredients in hair loss science — Minoxidil and Finasteride — alongside a supporting cast of botanical and conditioning ingredients including Saw Palmetto Extract, Biotin, Keratin, and Green Tea. Applied directly to the scalp, it delivers active support exactly where hair care begins: at the root.

Who It Is For: For adults experiencing hair thinning, hair loss, or reduced scalp density who want an active, clinically studied treatment.
