What finasteride does
Finasteride reduces the body's production of DHT, the hormone that gradually shrinks hair follicles in pattern hair loss. By lowering DHT, it slows the loss and, for many men, helps regrow some hair over time. It targets the underlying hormonal driver rather than just supporting growth.
What to realistically expect
For many men, finasteride helps slow or stop hair loss and can lead to some regrowth, though results vary from person to person. It tends to work best when started early, before significant loss. It's a maintenance treatment: benefits are sustained with continued use and generally fade if you stop.

Some early shedding as the hair cycle resets is normal. Read more on the hair-loss treatment timeline.
Oral vs topical finasteride
Finasteride comes as an oral tablet and, increasingly, as a topical applied to the scalp - sometimes blended with minoxidil. Topical formulas aim to limit how much of the medicine reaches the rest of the body. Providers like Happy Head offer customizable topical options, while Maximus offers oral finasteride and dutasteride plus a compounded topical.
Is it right for you?
Finasteride is generally used by men and isn't recommended for most women, especially during pregnancy. A licensed clinician can confirm whether it fits your situation and monitor you over time. This article is general information, not medical advice.
