The prescription-strength standard for male-pattern hair loss — now prescribed online, reviewed by licensed providers, and shipped discreetly from U.S. pharmacies.
Finasteride blocks 5-alpha-reductase, lowering DHT — the hormone that shrinks hair follicles. It is FDA-approved for male-pattern hair loss and is the most clinically established medication for stopping the thinning process.
By lowering DHT, finasteride removes the pressure that shrinks follicles over time — treating the cause, not just the symptom.
One of the most prescribed and studied hair-loss medications in the world, with a well-characterized profile.
Choose a once-daily tablet or a topical formulation — your provider helps you decide which fits your routine.
For most men, finasteride halts further thinning and, with time, can help thicken and regrow hair at the crown and hairline.
Finasteride inhibits 5-alpha-reductase, the enzyme that converts testosterone into DHT — the hormone that drives male-pattern hair loss.
With less DHT, hair follicles stop shrinking. The thinning process that shortens each hair's growth cycle is halted at the source.
Over months of consistent use, protected follicles produce thicker, healthier hair — helping maintain and, for many men, regrow it.
Finasteride is an FDA-approved 5-alpha-reductase inhibitor — the prescription standard for male-pattern hair loss. It lowers DHT, the androgen hormone responsible for shrinking hair follicles at the crown and hairline.
It's taken once daily, either as an oral tablet or a topical formulation. Because it works by removing the hormonal signal that thins hair, consistent daily use is what protects your results over time.
Start your visit →Finasteride is intended for men with male-pattern thinning at the crown and hairline. It's most effective when started early, before follicles are permanently lost. Your provider confirms it's appropriate based on your health history.
Finasteride is a daily medication — consistency is what makes it work. Results build gradually and effects reverse if you stop.
Your provider selects the right form and dose:
Finasteride can harm a developing male fetus. Women who are pregnant or may become pregnant should not take finasteride or handle crushed or broken tablets. Keep it stored safely away from others in the household.
Most men tolerate finasteride well. Uncommon sexual side effects — such as reduced libido or difficulty with erections — occur in a small percentage of men and are 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.
