Finasteride is prescribed at 1mg because it is FDA-approved and proven effective, despite evidence that 0.2mg may similarly reduce DHT. The 1mg dose is more effective for hair growth, and lower doses are less available.
Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
Creatine may worsen hair loss in some, especially with androgenic alopecia, but evidence is mixed. Some users experience no hair loss when using creatine with minoxidil and finasteride, while others notice increased shedding.
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.
