Take oral Dutasteride

Take one 0.5mg dutasteride capsule daily, prescribed off-label by a dermatologist. It is not FDA-approved for hair loss but is widely used when finasteride proves insufficient.

Why It Works

Dutasteride blocks both type I and type II 5-alpha reductase enzymes, reducing DHT levels by over 90% — compared to finasteride's 70%. Studies show it produces significantly greater hair count improvements than finasteride, making it a second-line option for non-responders.

Tips

• Higher potency means a higher risk of side effects — discuss thoroughly with your doctor
• Has a very long half-life (5 weeks), so effects persist long after stopping
• Often considered after 12+ months of inadequate response to finasteride
