    GlossaryNonsteroidal Inhibitors

    compounds that block biological processes without using steroids

    Nonsteroidal inhibitors are compounds that block specific biological processes without using steroid structures. In the context of hair and alopecia, these inhibitors can target enzymes or pathways involved in hair loss, such as 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT), a hormone linked to hair thinning and loss.

Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.

      Pyrilutamide did not show effectiveness in regrowing hair compared to a placebo, but it may still help maintain existing hair by preventing DHT from causing follicle miniaturization. Some users believe it could be beneficial when used with other treatments like minoxidil, finasteride, and dutasteride.
