AHK-Cu vs PTD-DBM
Copper-peptide hair research vs Wnt-pathway hair peptide.
| Attribute | AHK-Cu Alanine-Histidine-Lysine copper | PTD-DBM Wnt pathway hair peptide |
|---|---|---|
| Category | Skin, Hair & Beauty | Skin, Hair & Beauty |
| Best known for | Hair growth research | Wnt-pathway hair regrowth research peptide |
| In plain English | AHK-Cu is GHK-Cu's hair-focused cousin. Same copper-peptide concept, slightly different sequence with stronger research-interest in follicle stimulation. | It is the 'unblock the hair growth signal' peptide — releasing a brake on Wnt signaling so dormant hair follicles get the regrowth message. |
| How it works | Stimulates dermal papilla cells and VEGF expression in research models, encouraging hair follicle activity. | Disrupts CXXC5-DVL interaction, releasing inhibition of the Wnt/β-catenin pathway critical for hair follicle anagen entry. |
| Researchers study | Androgenetic alopecia, hair follicle stimulation, and hair shaft thickening. | Hair follicle regeneration, comparison with minoxidil, wound healing, dermal papilla cell research. |
| Internet discussion | Discussed alongside minoxidil and microneedling. | Heavily discussed in hair-loss communities as a frontier alternative to finasteride and minoxidil. |
AHK-Cu
Hair growth research
AHK-Cu is GHK-Cu's hair-focused cousin. Same copper-peptide concept, slightly different sequence with stronger research-interest in follicle stimulation.
Stimulates dermal papilla cells and VEGF expression in research models, encouraging hair follicle activity.
Androgenetic alopecia, hair follicle stimulation, and hair shaft thickening.
Discussed alongside minoxidil and microneedling.
AHK-Cu is a copper peptide specifically researched for hair follicle stimulation.
PTD-DBM
Wnt-pathway hair regrowth research peptide
It is the 'unblock the hair growth signal' peptide — releasing a brake on Wnt signaling so dormant hair follicles get the regrowth message.
Disrupts CXXC5-DVL interaction, releasing inhibition of the Wnt/β-catenin pathway critical for hair follicle anagen entry.
Hair follicle regeneration, comparison with minoxidil, wound healing, dermal papilla cell research.
Heavily discussed in hair-loss communities as a frontier alternative to finasteride and minoxidil.
PTD-DBM is a cell-permeable peptide studied for hair regrowth by enhancing Wnt/β-catenin signaling.
