Finasteride vs minoxidil: which should I start with?

Short answer: it depends on your sex, whether you can take systemic meds, and your goals. For most men with male-pattern (androgenetic) hair loss, doctors usually recommend starting finasteride (oral) to stop progression and adding topical minoxidil if you want extra regrowth. For women—especially those who are pregnant, trying to conceive, or of childbearing potential—topical minoxidil is the usual first choice; finasteride is generally avoided.

Quick breakdown

• How they work

  • Finasteride (oral, e.g., Propecia or generic finasteride 1 mg): lowers scalp DHT and prevents further miniaturization of hair follicles. Best at halting progression.
  • Minoxidil (topical, e.g., Rogaine, Kirkland Signature): a topical stimulant that can promote hair regrowth and thicken existing hairs. Best effect at the crown; less reliable at receding front/topline.

• Typical recommendation by group

  • Men not trying to father children and without contraindications: start finasteride 1 mg daily (generic is inexpensive and widely available). Expect to wait ~3–6 months to see effect; use continuously. Add topical minoxidil (5% foam or solution such as Rogaine or cost-effective Kirkland) if you want improved regrowth.
  • Women (especially pregnant or planning pregnancy): use topical minoxidil (5% foam is effective and well tolerated). Avoid finasteride in women of childbearing potential because of potential fetal risk.
  • If you prefer to avoid systemic meds or are worried about sexual/psych effects: start with topical minoxidil alone.

• Side effects and monitoring

  • Finasteride: possible decreased libido, erectile dysfunction, mood changes in a small percentage; effects generally reversible after stopping but discuss with your clinician. Women who could be pregnant must not handle crushed tablets.
  • Minoxidil: local scalp irritation, itching, or unwanted facial hair; some users experience temporary increased shedding early on.
  • Both need continuous use—stopping reverses benefits.

• Practical brands/services

  • Finasteride brands: Propecia (brand), many inexpensive generics (finasteride 1 mg).
  • Minoxidil brands: Rogaine (brand), Kirkland Signature (Costco) and generic minoxidil solutions/foam are effective and cheaper.
  • Telemedicine services that commonly prescribe finasteride: Keeps, Hims, Roman, Nurx, Lemonaid. For complex cases or diagnostic uncertainty, see a dermatologist.

If you want a specific recommendation: tell me your sex, age, whether you’re trying for pregnancy or have concerns about sexual side effects, and whether you prefer prescription telemedicine or an in-person dermatologist. I can then suggest the best starter plan and where to get it.
