What Are Hair Research Peptides?
Hair research peptides are copper-binding tripeptides studied for their role in dermal-papilla-cell activity and the hair-follicle growth cycle. This collection focuses on the two copper peptides most cited in follicular and dermal literature — GHK-Cu and AHK-Cu — supplied lyophilized at high purity for laboratory research use only.
How Copper Peptides Are Studied in Follicle Models
GHK-Cu, a naturally occurring copper tripeptide, is researched for collagen synthesis, extracellular-matrix remodeling, and dermal-papilla signaling. AHK-Cu is a fully synthetic copper tripeptide developed for follicle-specific research, studied for VEGF expression and Wnt/β-catenin signaling in the telogen-to-anagen transition. The copper ion in both serves as a cofactor for matrix-remodeling enzymes such as lysyl oxidase.
GHK-Cu vs AHK-Cu
| Compound | Origin | Primary research focus |
|---|---|---|
| GHK-Cu | Naturally occurring | Collagen / ECM, dermal & follicular |
| AHK-Cu | Fully synthetic | Dermal-papilla, Wnt/β-catenin, VEGF |

Frequently Asked Questions
Which peptides are studied for hair research? The copper tripeptides GHK-Cu and AHK-Cu are the most-cited in follicle and dermal-papilla research models.
What is GHK-Cu studied for in follicle models? GHK-Cu is researched for collagen synthesis, ECM remodeling, and dermal-papilla-cell signaling. It is a research compound only.
How does AHK-Cu differ from GHK-Cu? AHK-Cu is fully synthetic and developed for follicle-specific research, with reported emphasis on Wnt/beta-catenin and VEGF pathways, whereas GHK-Cu occurs naturally and has broader dermal relevance.
What pathways do these peptides target in research? Studies focus on dermal-papilla-cell proliferation, the hair-growth cycle, VEGF expression, and copper-dependent matrix remodeling.
Are hair research peptides approved for human use? No. Both compounds are supplied strictly for laboratory research use only and are not approved for human or veterinary use.
