The Proven Regrowth Treatment
Minoxidil (brand name Rogaine, plus many generics) is FDA-approved and works for both men and women. Studies consistently show it increases hair count and thickness, especially at the crown. The 5% strength is generally more effective than 2%, and it comes as a foam, a liquid solution, or — increasingly — a low-dose oral pill prescribed off-label.
How It Works
Unlike finasteride, minoxidil doesn't affect hormones. It's a vasodilator that increases blood flow to the scalp and, more importantly, extends the growth (anagen) phase of the hair cycle, so follicles stay productive longer and produce thicker strands. That's why it pairs so well with finasteride — see finasteride vs minoxidil.
The Early Shed Is Normal
Many people panic in the first 2–8 weeks when they notice more shedding. This 'dread shed' is actually a good sign: minoxidil pushes old hairs out to make room for new growth. It passes, and visible improvement typically appears around 3–4 months, with fuller results by 6–12 months.
Oral or Topical?
Topical minoxidil is available over the counter but requires a daily scalp routine. Low-dose oral minoxidil is prescription-only and more convenient, though it needs medical oversight. We break down the trade-offs in oral vs topical minoxidil. Providers like Hims and Happy Head offer both.
