Finasteride vs minoxidil: which should I start with?

Short answer

• If you are a man with classic male-pattern hair loss and are comfortable taking a prescription: start finasteride (oral 1 mg) as the foundation — it’s the best single medicine for stopping loss and regrowing hair on the crown — and add topical minoxidil for extra regrowth.
• If you are a woman, pregnant/planning pregnancy, or don’t want a prescription/possible sexual side effects: start topical minoxidil (OTC).
• If you’re uncertain, a safe first step is topical minoxidil while you discuss finasteride with your clinician.

Why (mechanisms and effect)

• Finasteride (oral 1 mg, brand Propecia or generic finasteride) blocks DHT, the hormone that causes follicle miniaturization. It’s especially effective at preventing further loss and regrowing hair on the vertex. Results usually begin at ~3–6 months, better at 6–12 months.
• Minoxidil (topical, brand Rogaine or generics like Kirkland) is a vasodilator that directly stimulates follicles. It can thicken hair and promote regrowth but tends to be less powerful than finasteride for male-pattern baldness. Works for men and women. Expect 3–6 months to see changes, up to a year for full effect.

Side effects and safety

• Finasteride: possible decreased libido, erectile dysfunction, mood changes, and teratogenic risk (must not be used by pregnant women). Discuss with your doctor; effects often reverse after stopping but can persist rarely. It requires a prescription and sometimes baseline discussion about PSA if you’re older.
• Minoxidil: scalp irritation, itching, unwanted facial/body hair (with excess application). OTC and widely tolerated.

Practical recommendations (brands and services)

• Finasteride: Propecia (brand) or generic finasteride 1 mg (cheaper, same active ingredient). Telehealth services that prescribe and ship finasteride include Keeps, Hims, Roman, and Nurx — convenient if you don’t have a local clinician.
• Minoxidil: Rogaine (5% foam for men; 5% or 2% formulations for women), or cost-effective generics like Kirkland Minoxidil 5% solution/foam. Use consistently; don’t expect immediate results.
• If you want combination products or topical finasteride, some compounding pharmacies and clinics offer topical-finasteride formulations and combo minoxidil/topical finasteride products — discuss with a dermatologist.

Combination therapy

• Using both finasteride (oral) and topical minoxidil usually gives better results than either alone and is a common approach for men who tolerate finasteride.

How long to try before judging

• Give any of these treatments at least 6 months (ideally 12 months) to judge effectiveness. Stopping them typically leads to loss of the newly gained hair over months.

Next steps

• If you’re male and okay with prescription meds: talk to your primary care doctor or use a reputable telehealth service (Keeps, Hims, Roman) to get finasteride 1 mg and start topical minoxidil concurrently.
• If you’re female, pregnant, or want to avoid systemic meds: start topical minoxidil (Rogaine Women 5% foam or a generic) and see a dermatologist if you don’t respond.
• If you want personalized advice or have health conditions (low libido, depression history, fertility concerns, or PSA monitoring needs), see your doctor or a dermatologist before starting finasteride.

If you tell me your sex, age, any medical history, and whether you’re open to a prescription, I can give a specific starter plan (dosage and product suggestions).
