A few private questions, then a licensed provider reviews your answers.
Finasteride is a 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, treating the cause of thinning rather than just its symptoms.
It's taken once daily, either as an oral tablet or a topical formulation applied to the scalp. Because it works by removing the hormonal signal that thins hair, consistent daily use is what protects your results over time — one of the most studied and prescribed hair-loss medications in the world.
Your provider recommends the right form and dose based on your intake and health history during your online visit — the oral tablet with decades of evidence, or a topical formulation that some men prefer.
Male-pattern hair loss is driven by DHT — a hormone your body makes from testosterone that gradually shrinks follicles at the crown and hairline. Over time, each affected follicle produces thinner, shorter hairs until it stops growing altogether. It's the most common cause of hair loss in men, it's genetic and progressive, and finasteride works by lowering the DHT that drives it.
Male-pattern loss is progressive — untreated, follicles keep shrinking and the thinning tends to advance rather than resolve on its own.
Finasteride works on active follicles, so treating early — before follicles are permanently lost — protects the most hair. Sooner is better than later.
The short answer: DHT-blocking shampoos only touch the surface, over-the-counter minoxidil stimulates growth without addressing the hormone, and prescription finasteride blocks the DHT that shrinks follicles in the first place.
| DHT shampoo (OTC) | Minoxidil (OTC) | Finasteride (Rx) | |
|---|---|---|---|
| What it targets | Surface scalp, mild shedding | Blood flow to follicles | The DHT that shrinks follicles |
| How it works | Cleanses, may slow shedding slightly | Stimulates growth, doesn't block DHT | Blocks DHT at the source |
| Addresses the cause | No | No — stimulates, doesn't block | Yes — lowers the hormone driving loss |
| Provider involved | No | No | Yes — reviews your health history first |
| Best for | Very early, mild shedding | Regrowth stimulation | Stopping male-pattern loss |
Many men try shampoos and OTC minoxidil first, find they only slow shedding or stimulate growth without stopping the cause, and move to a prescription. Finasteride is the step that treats the hormone driving loss — with a provider in the loop and a form chosen to fit your routine.
It works by lowering DHT — inhibiting the enzyme that converts testosterone into the hormone that shrinks follicles, so the thinning process is halted at its source and protected follicles can grow thicker hair again.
Finasteride inhibits 5-alpha-reductase, the enzyme that converts testosterone into DHT — the hormone that drives male-pattern hair loss.
With less DHT, follicles stop shrinking. The thinning 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.
It's for men with male-pattern thinning at the crown or a receding hairline — and it's most effective when started early, before follicles are permanently lost.
Men noticing male-pattern thinning at the crown or a receding hairline — the loss finasteride is built to treat.
Finasteride works best on active follicles, so starting sooner protects the most hair. Earlier is better than later.
For most men it halts further thinning and, with time, can help thicken and regrow hair at the crown and hairline.
A once-daily tablet or topical that builds into your day — with automatic refills so you never miss a dose.
Finasteride is not for women who are or may become pregnant — it can harm a developing male fetus, and crushed or broken tablets should not be handled. If your goal is purely to stimulate regrowth rather than block DHT, Minoxidil may be a better fit. And if you have scalp infection, unusual shedding, or undiagnosed symptoms, mention them in your visit for evaluation first.
You complete a private online visit, a licensed provider reviews it, and — if appropriate — your prescription ships to your door. No insurance required, no in-person appointment, no waiting room.
A short intake about your hair loss and health history, on your own time.

Your finasteride ships from a U.S. pharmacy in plain, unmarked packaging to all 50 states. Automatic refills available, and you can message your care team anytime.
Pricing is shown at checkout — no insurance needed, no hidden fees.
You take finasteride once daily — oral or topical — and consistency is what makes it work. Results build gradually over 3–6 months, and your provider sets the right form and dose for you.
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 occur in a small percentage of men and are usually reversible after stopping. Possible side effects include:
Tell your provider about all medications and conditions before starting. Seek care for any persistent or concerning symptoms, including breast lumps or changes, and message your care team if side effects don't resolve — they can adjust or pause your treatment.

| Treatment | What it is | Focus | Form | For | Rx required |
|---|---|---|---|---|---|
| Finasteride Popular | A DHT-blocker (5-ARI) | Stops loss | Oral / topical | Men | Yes |
| Minoxidil | A topical or oral vasodilator | Stimulates regrowth | Topical / oral | Men & women | Yes |
| Finasteride + Minoxidil | Combination therapy | Stop loss + regrow | Topical / oral | Men | Yes |
| Dutasteride | A stronger dual 5-ARI | Blocks more DHT | Oral | Men | Yes |
Yes — finasteride is one of the most clinically established hair-loss treatments. By lowering DHT, it stops further thinning in the large majority of men, and many also see regrowth at the crown and hairline over time. It works best when started early and taken consistently.
Oral finasteride is the classic once-daily tablet with decades of evidence. Topical finasteride is applied to the scalp and may lower the amount absorbed systemically, which some men prefer. Both target DHT; your provider helps you choose the form that best fits your goals and tolerance.
Most men tolerate finasteride well. A small percentage report sexual side effects — such as reduced libido or difficulty with erections — which are usually reversible after stopping. Women who are or may become pregnant should not take finasteride or handle broken tablets. Discuss your history with your provider.
Most men notice a difference in 3–6 months, with continued improvement up to a year. Hair grows slowly, so patience and consistent daily use are key. Many providers suggest before-and-after photos to track progress objectively.
Yes — finasteride and minoxidil are commonly stacked because they work through different pathways. Finasteride blocks DHT to stop loss, while minoxidil boosts blood flow to stimulate growth. Together they're one of the most effective combinations for male-pattern hair loss.
Finasteride is not approved for use in women and is not recommended for women who are or may become pregnant, as it can harm a developing male fetus. Women should not handle crushed or broken tablets. Women experiencing hair loss should talk with a provider about options intended for them.
