Is DHT actually the cause of male pattern hair loss or just a correlating factor? Why I think the research is more complicated than we're told and why I've been looking into GHK-Cu
    5/7/2026

    From the encyclopedia
    Finasteride →

    Popular 5-alpha reductase inhibitor that lowers DHT, taken as a pill or used topically

    Minoxidil →

    Vasodilator used on the scalp and, at low doses, as a tablet

    GHK-Cu →

    Copper peptide used in skin and hair cosmetics

    At a glance
    In this research discussion post, the primary subjects mentioned are
    💊 Finasteride (oral) 2 years
    💧 Minoxidil (topical) 2 years
    • GHK-Cu (subcutaneous injection) 3mg daily 7 weeks
    the tone is 😐 neutral with increased scalp density, new short hairs results.

    Other terms

    DHT is not the only cause of male pattern hair loss; genetic sensitivity, inflammation, and fibrosis also contribute. GHK-Cu, a copper peptide, is being explored as an alternative treatment to finasteride and minoxidil, showing potential in improving follicle health.
