Short answer
- If you are a man with typical male-pattern (androgenetic) hair loss: the most effective approach is usually finasteride plus topical minoxidil. If you must pick one first, finasteride (oral 1 mg daily) is generally better at stopping progression and producing regrowth; minoxidil is a good alternative if you want an OTC topical or prefer to avoid systemic drugs.
- If you are a woman: start with topical minoxidil. Oral finasteride is usually avoided in women of childbearing potential (teratogenic) and considered only in select, closely supervised cases (often postmenopausal women).
- If your hair loss is sudden, patchy, inflamed, or accompanied by other symptoms, see a doctor first — it may not be androgenetic alopecia.
How they work and what to expect
- Finasteride (oral, typical dose 1 mg/day — brand: Propecia; generics widely available): blocks conversion of testosterone to DHT, the hormone that drives male-pattern hair loss. Benefits: often better at halting progression and producing thicker regrowth on the crown. Onset: you may notice stabilization by 3–6 months, more regrowth by 6–12 months. Side effects: sexual side effects (reduced libido, erectile dysfunction) in a minority, possible mood effects; it lowers PSA levels (tell your clinician before prostate testing). Avoid in pregnancy and handle tablets carefully around pregnant women.
- Minoxidil (topical 2% or 5% solution/foam — brands: Rogaine; cheaper generics or retailer brands like Kirkland): a vasodilator applied to the scalp that can thicken hair and promote regrowth. Benefits: OTC, few systemic effects. Onset: expect 3–6 months to see benefit; may cause initial increased shedding as follicles cycle. Side effects: scalp irritation, unwanted facial/body hair if it spreads. 5% foam once daily is common for men; women usually start with 2% or 5% foam depending on tolerance and doctor’s advice.
Combination therapy
- Using both oral finasteride and topical minoxidil gives better results than either alone for many men. Dermatologists commonly recommend the combination when appropriate.
Practical points
- Access: minoxidil is OTC; finasteride requires a prescription (Propecia or generic finasteride). Some people try topical finasteride formulations to reduce systemic exposure — discuss with your dermatologist.
- Duration: you must continue treatment to maintain benefit. Stopping either will typically lead to reversal of gains within months.
- Monitoring: discuss sexual side effects and mood changes with your prescriber; men on finasteride should inform clinicians before PSA testing.
- If you have other medical conditions or take medications, check with your clinician before starting finasteride.
Brand recommendations (examples)
- Minoxidil: Rogaine (well-known), Kirkland Signature (cost-effective generic OTC), Rogaine foam 5% (men), Rogaine 2% solution or 5% foam (women per doctor’s advice).
- Finasteride: Propecia (brand 1 mg tablet) or generic finasteride 1 mg (usually less expensive). See a prescriber to discuss suitability.
Recommendation for you
- If you’re a man and comfortable with a prescription: consider starting both oral finasteride (1 mg daily) and topical minoxidil (5% foam or solution) after talking with your doctor.
- If you prefer to avoid systemic medication or want to try an OTC first: start minoxidil now and reassess after 3–6 months; consider adding finasteride if results are limited.
- If you’re a woman: start topical minoxidil and see a dermatologist for evaluation before considering oral finasteride.
