A Risk-Benefit Assessment of Treatment with Finasteride in Benign Prostatic Hyperplasia

How Finasteride and Dutasteride help reduce hair loss by reducing the amount of DHT in scalp areas, as well as discussing factors such as sensitivity to DHT, 5α-reductase expression in different parts of the hair follicle, and scalp tension.

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 natural DHT blockers like rice bran oil, which may reduce 5α-reductase activity similarly to Minoxidil and Dutasteride. One user argues that finasteride is more reliable and effective than natural alternatives.

Topical finasteride can effectively reduce scalp DHT by targeting local enzymes, despite less systemic impact compared to oral forms. Combining oral dutasteride with topical finasteride and minoxidil may enhance hair loss prevention, though evidence of its effectiveness is limited.

Dutasteride reduces DHT more effectively than finasteride, but finasteride is more commonly used and approved for hair loss. Users have mixed opinions on dutasteride's effectiveness, with some experiencing better results and others facing side effects or no improvement.

The conversation concludes that finasteride, a 5α-Reductase inhibitor used for hair loss, does not impair cognition either short-term or long-term. It suggests "brain fog" is not caused by the medication.
