The user has been using finasteride for almost a year, starting at age 18, and added tretinoin and 5% topical minoxidil 1-2 months ago. They are concerned about hair receding again despite the treatments.
Reducing sebum can indirectly lower DHT levels, with treatments like accutane, tretinoin, and green tea extract acting as DHT blockers. Accutane can lower DHT levels by reducing 5α-reductase activity, but its impact on hair varies.
A user suggests making a potent sulforaphane topical to degrade DHT and promote hair growth. Another user notes that sulforaphane's low molecular weight might also lower systemic DHT.
The user is experiencing increased hair shedding after one year of using oral dutasteride. They are seeking opinions on their DHT test results, which show levels below baseline.
