Comparison of Finasteride, a 5α Reductase Inhibitor, and Various Commercial Plant Extracts in In Vitro and In Vivo 5α Reductase Inhibition

Minoxidil, finasteride, and RU58841 are discussed as treatments for hair loss, with excitement around a new drug, PP405, and a reformulated oral minoxidil in trials. Concerns about cost, side effects, and long-term use are also mentioned.

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.

Finasteride is effective for treating male pattern baldness (MPB) with minimal side effects, and topical finasteride is similarly effective. Dutasteride is also effective but less understood, and Minoxidil is less effective than Finasteride.

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

OP used finasteride 1mg and 2.5mg oral minoxidil since late April, showing hair improvement despite some initial libido issues. Users discussed side effects, costs, and alternative treatments, with OP noting increased facial hair but no significant body hair growth.

A 25-year-old is using 1.25mg finasteride six times a week and 5% topical minoxidil daily for hair loss. They are experiencing reduced libido and erectile issues, possibly due to stress, and are questioning if the finasteride dosage is affecting DHT suppression.
