Reduced Prostate Cancer Risk in Patients with Androgenetic Alopecia Using 5-Alpha Reductase Inhibitors: A TriNetX Real-World Cohort Study

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.

Epristeride is a selective 5 alpha reductase type 2 inhibitor that may reduce scalp DHT similarly to finasteride, with potentially fewer side effects. It is suggested that combining epristeride with finasteride or dutasteride could enhance hair loss treatment effectiveness.

A 27-year-old male with Norwood grade 5 hair loss is using dutasteride and a hair serum with Redensyl, Anagain, Procapil, and Capilia Longa, but is hesitant to use oral minoxidil due to past allergic reactions to topical minoxidil. He plans to try dutasteride alone for 3 months before considering adding oral minoxidil.

A 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.

L. reuteri, a probiotic, is being explored for its potential benefits in treating androgenic alopecia, possibly enhancing finasteride's effects and reducing inflammation. The user combines this with finasteride, oral minoxidil, and other supplements, noting some improvement in hair loss.

A user experienced hair thinning after using tamoxifen and bupropion and is now using topical dutasteride, alfatradiol, melatonin, adenosine, and specific shampoos for improvement. They are considering using steroids and are seeking advice on whether combining oral dutasteride with TRT/PEDs would affect hair health, with mixed opinions on the impact of testosterone and DHT on hair loss.
