How each one works
Finasteride is an oral prescription that lowers DHT, the hormone behind pattern hair loss, tackling the root cause. Minoxidil works differently - applied to the scalp (or taken orally by prescription), it supports the growth phase of the hair cycle. Because they act through separate mechanisms, they're frequently used together.
The key differences
Finasteride is prescription-only and generally used by men (it isn't recommended for most women, especially during pregnancy). Minoxidil is available over the counter at 5% and, by prescription, at higher strengths or combined with other actives - and certain minoxidil formulas are used by women. Finasteride is a daily tablet; minoxidil is usually a topical you apply to the scalp.

Physician-prescribed finasteride and a 3-in-1 topical (minoxidil, finasteride, ketoconazole) for men's hair lossCan you use them together?
Yes - many effective plans combine finasteride and minoxidil, and some providers offer formulas that blend multiple actives into a single topical. A clinician can advise whether a combination is right for you and at what strengths. See how leading providers approach this in our provider rankings.
Side effects to know
Both treatments are generally well tolerated, but each can have side effects. Finasteride can, in a minority of men, cause sexual side effects; minoxidil can cause scalp irritation or unwanted facial hair with topical use. A licensed provider reviews your history and helps weigh the benefits and risks for your situation.
Which should you choose?
There's no single right answer - it depends on your goals, whether you prefer oral or topical, and a clinician's assessment. Many people start with both. If you want a tailored plan, providers like Happy Head build personalized topical formulas, while Maximus offers a broad set of oral and topical prescription options.
