Peptide Hair & Scalp Support
AHK-Cu is a targeted copper tripeptide with hair-specific research behind it, studied in human follicle and dermal papilla cell models for its connection to follicle vitality, scalp resilience, and the visible appearance of fuller, stronger, healthier-looking hair.
That is why AHK-Cu sits at the center of this lightweight, leave-on scalp serum: targeted copper peptide care for a healthier-feeling scalp and fuller, denser-looking hair.
This is not a basic hydrating scalp serum. It is a peptide-focused root treatment designed to support the scalp environment where healthy-looking hair begins.
Powered by AHK-Cu, acetyl tetrapeptide-3, biotinoyl tripeptide-1, niacinamide, caffeine, pro-vitamin B5 panthenol, glycerin, and hyaluronic acid, this formula helps create the look and feel of a more supported scalp and stronger, healthier-looking roots.
The lightweight texture absorbs without greasiness, buildup, or root heaviness, making it easy to use daily on the scalp, along the part line, at the temples, or anywhere hair looks sparse, fragile, or less dense than you want it to.
Use consistently as a daily scalp ritual for refreshed roots, hydrated scalp comfort, and the appearance of fuller, denser, more resilient-looking hair over time.
Best for: scalp support, sparse-looking areas, fragile-looking hair, reduced density appearance, dry or tight-feeling scalp, and roots that need lightweight peptide care.

Finish: refreshed, balanced, non-greasy
Fragrance: none
Product Material: UV-Coated Glass
