Short answer
- For most adult men with male-pattern hair loss, the best starting approach is finasteride (oral 1 mg daily) plus topical minoxidil (usually 5% once daily or foam as directed). The combination gives the best chance to stop progression and regrow hair.
- If you’re worried about systemic side effects or are female (especially of childbearing potential), start with topical minoxidil alone.
- Talk with a clinician first — finasteride needs a prescription and isn’t safe in pregnancy.
Why (simple comparison)
- Finasteride (oral 1 mg, brand: Propecia; also widely available as generic finasteride): blocks conversion of testosterone to DHT, which is the main driver of male-pattern hair loss. It’s generally better at stopping progression and promoting regrowth than minoxidil for many men. Effects often begin at 3–6 months, with best results at ~12 months. Main risks: sexual side effects (lower libido, erectile dysfunction), possible mood effects; rare but important.
- Minoxidil (topical, brands: Rogaine; cost-effective generics/Kirkland also common): a vasodilator that increases hair size and growth phase. Available OTC, safe for many people. Side effects are mostly local (scalp irritation, unwanted facial hair) and you can see temporary “shedding” early on. You must keep using it — hair is lost if stopped.
When to pick which
- Adult men comfortable with small risk of systemic side effects and wanting the strongest result: finasteride + minoxidil.
- Men who refuse oral meds or want to avoid sexual side-effect risk: start minoxidil alone (or consider topical finasteride through a dermatologist/compound pharmacy, though evidence and availability vary).
- Women (especially of childbearing potential): start with topical minoxidil (Rogaine for Women). Do not take finasteride if pregnant or trying to conceive; finasteride is generally not recommended for women of childbearing potential.
- Teens: hair-loss meds are usually for adults — see a doctor.
Practical notes and brands/services
- Prescription finasteride: brand Propecia or generic finasteride; for convenience many people use telemedicine hair services such as Keeps, Hims, or Roman for consults and refills (they connect you with clinicians and handle prescriptions). You can also see a dermatologist or your PCP.
- Minoxidil OTC: Rogaine (5% foam for men, 2% or 5% formulations for women), or generic/Kirkland for cheaper options.
- Topical finasteride products exist (compounded or some commercial formulations) — talk with a dermatologist if you want to minimize systemic exposure.
Follow-up and expectations
- Give either treatment several months to work (expect initial signs by 3–6 months; full benefit ~12 months). Continue long-term or benefits reverse.
- If you start finasteride, discuss baseline concerns and monitor side effects; stop and contact your clinician if you develop sexual dysfunction or mood changes.
- If your hair loss is sudden, patchy, or you have other symptoms (weight changes, irregular periods, anemia), get medical evaluation — it might not be pattern hair loss.
If you want, tell me: your sex, age, whether you might try pregnancy, and how you feel about oral meds/side effects — I can give a specific starter plan and suggest exact products or help find a telemedicine option.
