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.
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.
Sulforaphane shows potential for hair regrowth, with users reporting reduced shedding and regrowth. Some users combine it with Minoxidil and finasteride for better results.
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.
