Copper-binding tripeptide (alanine-histidine-lysine)

How it works
Delivers copper into tissue and upregulates VEGF, increasing follicular blood supply and extending the anagen growth phase in follicle models.
What research has shown
Follicle culture studies report increased dermal papilla cell proliferation and prolonged anagen phase compared with untreated controls.
