Effects of the 5α-Reductase Inhibitor Finasteride on Serum Levels of Gonadal, Adrenal, and Hypophyseal Hormones and Its Clinical Significance: A Prospective Clinical Study

Finasteride helps with hair loss by lowering DHT levels in the scalp, which is more important than blood DHT levels. If finasteride is not effective, consulting a doctor or considering switching to dutasteride may be advisable.

Finasteride is the most effective treatment for reducing DHT and addressing hair loss compared to fish oil and saw palmetto. Topical treatments like RU58841 and minoxidil are also discussed, but finasteride remains the most effective option.

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.

The conversation discusses the use of 5-alpha-reductase inhibitors like finasteride and dutasteride for hair loss in transgender women, particularly in relation to testosterone suppression. The original poster has been using dutasteride and is considering stopping it due to undetectable testosterone levels.

Dutasteride may inhibit androgen receptors in addition to reducing DHT, potentially explaining its effectiveness over finasteride for hair loss. Concerns about its impact on muscle growth are debated, with some suggesting no significant effects.

The conversation discusses whether to use finasteride for hair loss, considering its role in inhibiting DHT and 5AR, which can affect brain function and mood. Some users report anxiety and depression from finasteride, while others do not experience these side effects and emphasize the importance of DHT for brain and prostate health.
