  • Finasteride is a 5-alpha-reductase inhibitor that blocks conversion of testosterone to dihydrotestosterone (DHT) — the primary hormonal driver of androgenetic alopecia. GHK-Cu does not address the DHT pathway. Published GHK-Cu research has not documented direct anti-androgen activity.
  • The mechanistic gap means GHK-Cu does not replace finasteride's role in addressing the hormonal component of pattern hair loss. It targets the follicle microenvironment rather than the hormonal trigger.
