AHK-Cu is the signal. The formula around it is what makes the signal count.

A lightweight copper peptide scalp serum designed to support fuller-looking hair, stronger-looking roots, and a healthier scalp environment without oil, residue, or hormonal actives.

At 0.25%, AHK-Cu anchors a three-peptide system supported by research in human hair follicles and dermal papilla cells. Acetyl Tetrapeptide-3 supports the structural matrix associated with anchoring hair at the root, while Biotinoyl Tripeptide-1 adds a second follicle-directed peptide for fuller, denser, stronger-looking hair.

L-Histidine is the delivery intelligence. Used in a near-equimolar relationship to copper, it helps coordinate copper and support its handoff within the formula. Sodium PCA, Sodium Lactate, Serine and Glycine form an NMF-based matrix that binds water at the scalp surface, helping create a more favorable diffusion environment for water-soluble actives.

Niacinamide, Panthenol and Allantoin support barrier resilience, helping keep the scalp in condition for consistent daily treatment.

Not a hydrating scalp serum with peptides added. A follicle-directed copper system engineered around signaling, anchoring, copper coordination and delivery.

Designed for daily use without changing your wash schedule.
Water-light. Lipid-free. No oily finish. No sticky root residue.
