Topical vs oral finasteride
Medically reviewed byClay Buchanan, MD·Last reviewed September 2026
Oral finasteride is a once-daily pill; topical finasteride is applied to the scalp and may lower systemic exposure. Both aim to slow hair loss. A clinician helps you weigh side-effect profiles and choose, sometimes in combination with minoxidil.
The trade-off
Oral is simple and well studied. Topical may reduce systemic exposure for people concerned about side effects, though it can still be absorbed.
How long until you see anything?
Plan on 3–6 months of consistent use before reassessing. Individual results vary.
