5α-Reductase Type 2 Gene Variant Associations with Prostate Cancer Risk, Circulating Hormone Levels, and Androgenetic Alopecia

Sugary beverages increase the risk of pattern hair loss in men by 57%, and type 2 diabetes is linked to female pattern hair loss. Reducing sugar intake and using treatments like finasteride and minoxidil may help manage hair loss.

Dutasteride raises scalp testosterone by 99%, which may not be ideal for those sensitive to all androgens. Some argue finasteride's balancing act might be better, while others believe dutasteride is superior for hair regrowth.

Finasteride may affect neurosteroids, impacting mood and sexual function, with varied user experiences. Some report side effects like depression and sexual dysfunction, while others find it effective for hair retention or prefer alternatives like Dutasteride or topical treatments.

Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.

Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.

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.
