Comparison
Finasteride and minoxidil, compared from both labels
These are the only two ingredients approved for pattern hair loss, and they are not alternatives in the usual sense: they act differently, they are obtained differently, and one of them is approved for women.

Written by us
Two different kinds of treatment
Finasteride is a prescription tablet acting on the hormone involved in follicle shrinkage. Minoxidil is applied to the scalp, sold over the counter, and its mechanism is not fully established even now.
That difference decides almost everything practical: one requires a consultation and carries hormonal warnings including those about pregnancy exposure, the other can be bought in a supermarket in several countries.
What both labels agree on
Both describe treatment as continuing rather than as a course. Neither claims a permanent change after stopping, and both describe what maintains the effect rather than what ends the condition.
Both are approved for pattern hair loss specifically, not for hair loss in general, which matters because hair loss from other causes will not respond to either and is a reason to have the cause identified rather than assumed.
Questions
- Can both be used together?
- Clinicians commonly prescribe both, but neither label describes the combination, so this page reports only what the documents cover.
- Which one works for women?
- Minoxidil holds an approval for women in its own product with its own label, shown on the minoxidil page. Finasteride's hair loss approval is for men.
- Which is cheaper?
- Both are inexpensive. Generic finasteride is a few euros a month; own-label minoxidil is comparable. The cost difference between them is smaller than the difference between brand and generic within each.
