The effect of tripeptide-copper complex on human hair growth in vitro
H. K. Pyo, and colleagues · 2007 · Archives of Pharmacal Research. 2007;30(7):834–839.
Reported findings and study design
Donated human hair follicles ex vivo and cultured dermal papilla cells; not volunteers receiving treatment.
| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Follicle elongation and cell proliferation | Increased in ex vivo / in vitro models | |
| Apoptotic dermal papilla cells | Decrease was not statistically significant |
This study tested AHK-Cu, not GHK-Cu. Human follicle culture does not establish scalp hair regrowth in people.
