- Minoxidil is a potassium channel opener that primarily increases blood flow to hair follicles and extends the anagen growth phase through vasodilation. It does not directly address dermal papilla cell signaling or follicle stem cell activity.
- GHK-Cu operates through different pathways — DPC proliferation, TGF-beta1 suppression, stem cell recovery, and broad gene expression modulation. Published research describes these as complementary rather than competing mechanisms. The non-overlapping pathways are why community protocols commonly describe combining copper peptide topicals with minoxidil rather than substituting one for the other.
