Finasteride vs minoxidil: which should I start with?

Short answer

• For most men with male-pattern hair loss, start finasteride (oral) plus topical minoxidil for the best chance to stop loss and regrow hair.
• If you’re worried about systemic side effects or prefer topical-only treatment, start with minoxidil alone.
• For women, topical minoxidil is the usual first choice; finasteride is generally avoided in women of childbearing potential and used only under specialist supervision (sometimes in postmenopausal women).

Why: how they work and what to expect

• Finasteride (1 mg/day; brand: Propecia or generic finasteride) blocks DHT, the hormone that drives male-pattern baldness. It’s more effective than minoxidil at halting progression and producing meaningful regrowth in the crown/mid-scalp. Effects typically start at 3–6 months and maximize by ~12 months. It requires a prescription.
• Minoxidil (topical; brand: Rogaine — 5% foam for men; 2% solution or 5% foam for women — or cheaper generics like Kirkland) is a topical that stimulates hair growth and prolongs the growth phase. It can take 3–6 months to see results. It’s over‑the‑counter.

Key safety points

• Finasteride: possible sexual side effects (decreased libido, erectile dysfunction), mood effects in a small number of men; can lower PSA (important for prostate cancer screening interpretation). Not safe in pregnancy — women who are or may become pregnant must not handle crushed tablets. Discuss risks with your prescriber.
• Minoxidil: generally well tolerated; scalp irritation possible. If you stop either treatment, gained hair is usually lost within months.

Practical recommendations (based on common practice)

• If you want the most effective, evidence-backed approach and are an adult man: see a clinician to get a prescription for finasteride (generic finasteride or Propecia) and buy topical minoxidil (Rogaine 5% foam or generic). Use both—studies and clinical practice show they work better together.
• If you prefer to avoid oral meds or are trying treatment first: start minoxidil (Rogaine or generics).
• If you’re a woman: start topical minoxidil (Rogaine 2% or 5% foam for women). Don’t take finasteride if pregnant or planning pregnancy; discuss options (e.g., spironolactone, referral to dermatologist) if minoxidil is insufficient.

Where to get them

• Prescription finasteride: ask your PCP or dermatologist, or use telemedicine providers (examples: Roman, Hims, Keeps) that prescribe and deliver generic finasteride. Compare price and follow‑up services.
• Minoxidil: over the counter at pharmacies (Rogaine) or online (Amazon, Walmart, Costco/Kirkland) or at the telemedicine companies above.

Next steps

1. Decide if you’re comfortable trying an oral medication.
2. Book a visit with your PCP or a dermatologist (in-person or telemedicine) to discuss finasteride risks, get a prescription if appropriate, and set a monitoring plan.
3. Start minoxidil now if you want to begin treatment immediately (it’s OTC).
4. Expect to wait 3–6 months to see effects; continue treatment to maintain results.

If you tell me your sex, age, whether you’re concerned about side effects, or whether you prefer in‑person or telemedicine for prescriptions, I can give a tailored recommendation and suggest specific product options and dosing.
