- Finasteride works hormonally, blocking conversion of testosterone to DHT (dihydrotestosterone). Since DHT causes follicle miniaturization in androgenetic alopecia, reducing it helps maintain existing hair. The approach works well for many men but carries significant hormonal side effects including sexual dysfunction.
- GHK-Cu is non-hormonal. It doesn't block DHT, affect testosterone levels, or alter hormone balance. This makes it suitable for those who can't tolerate finasteride's side effects or prefer non-hormonal approaches. One user reported: "I have used GHK-cu injectable and topical and found no effect on E2 or DHT."
- The tradeoff is that GHK-Cu doesn't address the underlying hormonal cause of androgenetic alopecia. For hormone-driven hair loss, combining GHK-Cu with DHT-blocking treatments may produce superior results than either alone. The peptide supports follicle health while the anti-androgen protects against hormone-mediated damage.
