What the research examined
A 2007 experiment examined AHK-Cu in cultured dermal papilla cells and isolated human hair follicles. Researchers reported follicle elongation and cell-proliferation changes. One measure of reduced apoptotic cells did not reach statistical significance, an important qualification to the broader mechanistic interpretation.
How to interpret the findings
Human-derived cells and isolated follicles are laboratory models. This was not a clinical trial establishing hair growth in people, and it does not establish the performance of a commercial preparation.
