Short answer
- If you are an adult man with male-pattern (androgenetic) hair loss and you’re comfortable taking a prescription medicine, start finasteride (oral) — it’s the most reliable medicine to stop progression and often regrow hair. Many clinicians combine it with minoxidil for added benefit.
- If you are a woman, are planning pregnancy, or want to avoid systemic drugs, start with topical minoxidil (OTC Rogaine or generic equivalents).
- If you’re unsure or want convenience, use a telehealth service (Hims, Roman, Keeps) or see a dermatologist/PCP to get personalized advice and a prescription.
Why (brief)
- Finasteride (Propecia or generic finasteride 1 mg) blocks DHT, the hormone that causes male-pattern hair loss. It’s the single most effective oral therapy for men to stop hair loss and can produce regrowth over months.
- Minoxidil (Rogaine; generic 5% foam or 2% solution) is a topical vasodilator that stimulates hair growth and can thicken hairs. It’s OTC, safe for many people, and useful alone or combined with finasteride.
- Combination therapy (finasteride + minoxidil) often gives the best results because they work by different mechanisms.
Practical points
- Onset: Expect 3–6 months to see changes; best results often require 6–12 months. Continue treatment long term — stopping reverses benefit.
- Side effects:
- Finasteride: small risk of sexual side effects (reduced libido, erectile dysfunction) in a minority; discuss risks with your clinician. Not for women who are or may become pregnant (can cause fetal abnormalities).
- Minoxidil: scalp irritation, itching, or unwanted facial hair growth; generally well tolerated.
- Cost/brands: Generic finasteride is inexpensive versus brand Propecia. For minoxidil, Rogaine is the brand; Kirkland (Costco), Equate (Walmart) and other generics are cheaper and effective.
- Monitoring: Talk to your prescriber about baseline questions (sexual side effects, fertility plans). Men getting PSA tests should tell their clinician if they are taking finasteride because it lowers PSA levels.
- Access: Telehealth companies (Hims, Roman, Keeps) offer online consults, prescriptions and mail delivery for finasteride and minoxidil if you want convenience. For complex cases, receding hairline, scarring alopecia, or if unsure of diagnosis, see a dermatologist.
Suggested starting plans (depending on situation)
- Adult man comfortable with a prescription: start oral finasteride 1 mg daily (generic or Propecia) and add topical minoxidil 5% foam daily or every other day as tolerated.
- Man who prefers to avoid systemic meds or want to try OTC first: start minoxidil 5% foam (Rogaine or generic) and reassess at 4–6 months; consider switching/adding finasteride if progression continues.
- Woman (not pregnant / not planning pregnancy): discuss with a dermatologist; many women use minoxidil 2% or 5% (foam) first. Finasteride is not routinely recommended for women of childbearing potential.
If you want, tell me:
- your sex/age,
- how long you’ve had hair loss and a short description (receding hairline, thinning at crown, diffuse thinning), and I’ll recommend a specific starter plan and walk you through how to get prescriptions or OTC products.
