A more powerful DHT-blocker for men who don't respond enough to finasteride — dutasteride inhibits both types of the DHT-forming enzyme, prescribed online and shipped discreetly from U.S. pharmacies.
Dutasteride inhibits both types of 5-alpha-reductase — the enzyme that converts testosterone into DHT. Because it blocks more of the enzyme than finasteride, it produces a deeper reduction in DHT and is often chosen for men who don't respond enough to finasteride alone.
Dutasteride blocks both type I and type II 5-alpha-reductase — finasteride blocks only one — for a stronger drop in DHT.
A logical next step for men whose thinning continues despite consistent finasteride use.
A once-daily oral capsule that fits easily into your routine — consistency does the rest.
By deeply lowering DHT, it halts thinning at the source and can help thicken and regrow hair over time.
Dutasteride inhibits both type I and type II 5-alpha-reductase, the enzymes that convert testosterone into DHT — a broader block than finasteride.
With both enzyme types inhibited, DHT falls further than with finasteride, relieving more of the pressure that shrinks follicles.
Over months of consistent use, protected follicles can produce thicker, healthier hair — helping maintain and, for many men, regrow it.
Dutasteride is an oral dual 5-alpha-reductase inhibitor used for male-pattern hair loss. It blocks both types of the enzyme that forms DHT, producing a stronger reduction in the hormone than finasteride — which is why it's often chosen for men who need more.
It's taken as a low-dose oral capsule, usually once daily. Because it works by removing the hormonal signal that thins hair, consistent daily use is what protects your results over time.
Start your visit →Dutasteride is intended for men with male-pattern thinning — especially those who haven't seen enough benefit from finasteride. It's a stronger option, so your provider confirms it's appropriate based on your health history and goals.
Dutasteride is a daily medication — consistency is what makes it work. Results build gradually and effects reverse if you stop.
Your provider selects the right dose and cadence:
Dutasteride can harm a developing male fetus. Women who are pregnant or may become pregnant should not take dutasteride or handle the capsules, as it can be absorbed through the skin. Keep it stored safely away from others in the household.
Most men tolerate dutasteride well. Because it lowers DHT more than finasteride, sexual side effects may be somewhat more likely, though they are still uncommon and usually reversible after stopping.
Tell your provider about all medications and conditions. Seek care for any persistent or concerning symptoms, including breast lumps or changes.
