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.

Loved by our beauty community
“I lost a lot of hair from being on Ozempic for years now. I started using this product from samples I received roughly 3 months ago, and it has transformed my hairline. I have about an inch and a half of growth all the way around and I am growing new hair across my entire head.” - Tammy, 51
Published AHK-Cu Research
Growth begins beneath the strand.
AHK-Cu has been studied for its influence on living human hair follicles and dermal papilla cells, the specialized cells involved in regulating follicle growth.
Studied Range
10⁻¹²–10⁻⁹ M
Active Concentration Range
The range associated with increased follicle elongation and dermal papilla-cell proliferation.
Follicle Response
p < 0.001
Follicle Elongation
A statistically significant response reported in isolated human follicles.
Cell-Survival Marker
42.7%
Lower Cleaved Caspase-3
A reduction observed in a marker associated with programmed cell death in cultured dermal papilla cells.
Cell-Survival Marker
77.5%
Lower Cleaved PARP
A reduction observed in another apoptosis-associated marker in cultured dermal papilla cells.
What the research suggests
Extend
Supported elongation of living human follicles maintained outside the body.
Multiply
Stimulated proliferation of cultured human dermal papilla cells.
Preserve
Shifted several measured markers toward a more cell-survival-favorable profile.
Support
Supports the rationale for a follicle-focused signaling treatment.
Study Context
Results were observed in isolated human hair follicles and cultured dermal papilla cells. The study did not evaluate the finished AHK Hair & Scalp Serum, establish a human hair-growth percentage, or measure topical consumer results.
