Finasteride is a 5-alpha-reductase inhibitor that reduces the conversion of testosterone into dihydrotestosterone (DHT). It is the standard pharmaceutical treatment for androgenetic hair loss in men.
Key benefits
- Slows or halts DHT-driven hair loss
- Low 1 mg dose, well studied and well tolerated
- Particularly useful for athletes on testosterone-based cycles
- Simple once-daily oral tablet
Because elevated DHT is a common cause of hair thinning during anabolic steroid use, finasteride is frequently run as supportive therapy. Note that it works only on DHT-derived hair loss and should be taken continuously for sustained results.
