Inhibitory Activities of Puerariae Flos Against Testosterone 5α-Reductase and Its Hair Growth Promotion Activities

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

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.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

The conversation discusses alternatives to RU58841 for hair loss treatment, with suggestions including topical spironolactone, peppermint and rosemary oils, and saw palmetto. The user also considers ordering RU58841 from China but finds it too expensive.

The conversation discusses using a multimodal approach to treat androgenic alopecia, including substances like gamma-linolenic acid, DHA, sulforaphane, melatonin, cetirizine, astaxanthin, fisetin, apigenin, curcumin, limonene, genistein, and berberine. Users also mention using ketoconazole, minoxidil, and low-level laser therapy (LLLT) as part of their hair loss treatment regimens.

A person experienced hair regrowth after reducing testosterone levels and using saw palmetto tincture and Alpecin shampoo. Other users suggested treatments like Nizoral shampoo, Aldactone, and supplements for hair loss.
