Finasteride vs minoxidil — which is right for me?
Short answer
Finasteride lowers DHT systemically; minoxidil extends the anagen growth phase locally. They have different mechanisms and are commonly combined for additive effect.

Full answer
Finasteride and minoxidil treat androgenetic alopecia through different mechanisms. Finasteride is a systemic 5-alpha-reductase inhibitor that lowers DHT and addresses the underlying androgenic driver. Minoxidil is a topical (or low-dose oral) vasodilator that extends the anagen phase and increases follicle size. Combination therapy is common and additive. Within oMeds review, modality selection follows pattern of loss, patient preference, prior response, and side-effect tolerance.
