Alternatives

Minoxidil (topical or oral)

Different mechanism; works synergistically with finasteride. Topical: messy, lifelong. Oral low-dose minoxidil is increasingly common.

Dutasteride (off-label)

Stronger 5-alpha-reductase inhibition than finasteride. Greater efficacy in some studies; same side effect profile, possibly stronger.

Topical finasteride

Lower systemic absorption; growing evidence base. Compounded; not FDA-approved.

Hair transplant

Surgical solution — but most surgeons recommend continuing medical therapy after transplant to prevent further loss.
