    Glossary 5α-reductase inhibitory activity

    blocks enzyme converting testosterone to hair-loss-linked DHT

    5α-reductase inhibitory activity refers to the ability of a substance to block the action of the enzyme 5α-reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), a hormone linked to hair loss and conditions like benign prostatic hyperplasia. By inhibiting 5α-reductase, these substances can help reduce DHT levels, potentially preventing hair loss and treating related conditions.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 2 years ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

      community Does caffeine inhibit 5-α-reductase?

       4 upvotes 6 years ago
      Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

      community Sugar and Hair loss connections

      in Research/Science  41 upvotes 1 year ago
      High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.

      • Does Procapil block DHT without affecting hormones? What the evidence shows Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.
