Topical dutasteride is suggested as a low side-effect treatment for hair loss, with a proposed dose of 0.025% 1ml/day. It is considered better than finasteride due to its even inhibition of DHT isoforms and lower systemic absorption.
Pyrilutamide is believed to be more effective than RU58841 and 1 mg finasteride in treating hair loss, with no systemic hormonal effects and the potential to block more than 31% of scalp DHT. It may also antagonize scalp testosterone due to its action as an androgen receptor antagonist.
A new hair loss treatment, PP405, showed promising Phase 2a results with 31% of patients experiencing over 20% hair density increase without systemic absorption, avoiding hormonal side effects. The treatment is expected to be expensive, with Phase 3 trials starting mid-2026, and there is skepticism about the data's strength.
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.
Finasteride can increase estrogen levels, causing dizziness and nausea. Users discuss adjusting treatment and diet, and explore alternatives for hair loss management.
