Finasteride vs minoxidil: which should I start with?

Short answer

• If you are a man and your priority is to STOP further hair loss, finasteride (oral) is usually the single most effective starting choice. If you want to try a low‑risk, over‑the‑counter option first, start minoxidil (topical). The best results for men are usually the combination of finasteride + minoxidil.
• If you are a woman of childbearing potential, do NOT take finasteride (risk to a male fetus). Topical minoxidil is the usual first-line option for women.

Why (brief)

• Finasteride (finasteride 1 mg daily — brand: Propecia or generic finasteride) lowers scalp DHT and is the most effective medicine to stop progression of male pattern hair loss and often to regrow hair. Effects begin to show in 3–6 months, with best results around 12 months. Main risks: sexual side effects (libido, erectile dysfunction), mood changes in a small number of men, and it is teratogenic (dangerous for a pregnant woman’s male fetus).
• Minoxidil (topical 5% for men, 5% foam or 2% liquid commonly used for women — brand: Rogaine; cost‑effective generics: Kirkland, generic minoxidil) is available OTC, stimulates hair regrowth but is usually less potent than finasteride at stopping progression. Side effects are usually topical (scalp irritation, initial shedding, possible facial hair growth). Needs continuous use or hair will be lost again.

Specific brand and service suggestions

• Finasteride: Propecia (brand) or generic finasteride (cheaper). If you want an easy online prescription and follow‑up, telehealth providers that offer hair-loss care include Hims, Keeps, Roman. Compare prices (GoodRx helps with pharmacy pricing).
• Minoxidil: Rogaine (Johnson & Johnson) 5% foam for men; Women’s Rogaine 5% foam or 2% solution for women. Costco Kirkland minoxidil is a common lower‑cost generic.
• If you want an evaluation first, consider a dermatologist or a telederm/trichologist consult (many dermatologists offer virtual visits).

How to choose for yourself

• Male, comfortable with a prescription and low risk tolerance for further thinning: start finasteride (1 mg daily). Add minoxidil for faster/better regrowth.
• Male, prefer only topical/OTC or worried about systemic side effects: start minoxidil (Rogaine or generic).
• Female, especially of childbearing potential: start minoxidil (Women’s Rogaine). If post‑menopausal, a dermatologist may discuss other options.
• Rapid or patchy hair loss, scarring, redness, or other signs: see a dermatologist before starting treatment.

Monitoring and practical points

• Expect 3–6 months to see improvement; full effect 9–12 months. Continue treatment long‑term.
• If you try finasteride and notice sexual side effects or mood changes, stop and contact your clinician. Discuss baseline PSA with your doctor if you’re an older man.
• If cost is an issue, generic finasteride and generic minoxidil (Kirkland) are much cheaper than brand names.
