Dutasteride

Dutasteride is a powerful dual 5-alpha reductase inhibitor that blocks both Type I and Type II enzymes, reducing DHT levels by up to 90%—compared to finasteride's 70%. This makes dutasteride particularly effective for men with moderate to advanced hair loss or those who haven't achieved sufficient results with finasteride alone.

Studies show dutasteride produces significantly greater hair count increases compared to finasteride at 24 months. At hi-doctor.ai, our doctors may recommend dutasteride for patients who need a more aggressive treatment approach.

Dutasteride inhibits both Type I and Type II 5-alpha reductase enzymes, providing more comprehensive DHT suppression than finasteride. By blocking 90%+ of DHT production, it maximizes the potential for follicle recovery and regrowth.

Side effect profile is similar to finasteride but slightly higher in incidence: decreased libido (3-5%), erectile difficulty (2-4%), ejaculation disorders (1-2%). Effects are reversible. Dutasteride has a longer half-life (5 weeks) so effects take longer to clear after stopping.
