Hair Growth

Analog mouse data, Wnt/beta-catenin signaling, and what remains unproven in humans

Copper and the Hair Follicle

A 2023 mouse study showed a GHK-Cu analog entering the hair growth phase (anagen) in 6 days compared with 9 days for minoxidil 5%. That result is hypothesis-generating, not proof that GHK-Cu itself beats minoxidil in humans. The broader hair story combines Wnt/beta-catenin and dermal papilla data with copper-linked anti-androgen hypotheses, but clean human efficacy evidence is still missing.
