What Is Finasteride?
Finasteride is an FDA-approved oral medication that stops hair loss by blocking DHT, the hormone that shrinks hair follicles. It's the most effective treatment for male pattern baldness, stopping loss in 90%+ of men and regrowing hair in 65%.
How It Works
Male pattern baldness is caused by DHT (dihydrotestosterone), which shrinks hair follicles until they stop producing visible hair.
Finasteride blocks the enzyme (5-alpha reductase) that converts testosterone to DHT, reducing DHT levels by about 70%. Lower DHT = follicles can recover and produce thicker hair again.
Results Timeline
DHT levels drop. Some men experience temporary shedding (weak hairs pushed out). No visible improvement yet.
Hair loss slows or stops. Some early regrowth may be visible. Take photos to track progress.
Noticeable improvement in hair density for most responders. Regrowth continues.
Maximum results typically achieved. Continued use maintains results indefinitely.
Dosage
Standard dose: 1mg daily (oral tablet)
Lower dose option: Some providers prescribe 0.5mg or 0.25mg for men concerned about side effects. Research suggests these still provide significant DHT reduction.
Topical finasteride: Applied to scalp. May reduce systemic exposure while treating hair loss. Available at Hims and some compounding pharmacies.
