Minoxidil (topical)

Over-the-counter foam or liquid you apply to the scalp. FDA-approved for hair loss.

Strong evidenceNo prescription

The cheapest legitimate way

Buy generic 5% minoxidil (store brands like Kirkland) in multi-month packs. Same active ingredient as the name brands.

Smart path~$4–$8/mo generic

Typical brand price~$20–$25/mo via subscription brands

Prices are estimates based on typical US cash prices. They change often, so check before you buy.

Evidence: Strong. Backed by large, well-designed studies.
How it works: Minoxidil widens blood vessels and extends the growth phase of hair. It helps hair grow but does not block DHT, so it pairs well with finasteride.
What results look like: Regrowth or thickening for many men, especially on the crown. 5% works better than 2%.
Time to results: Expect a shed in weeks 2–8 (normal). Judge results at 6 months.
Side effects and downsides: Scalp itching or flaking (more common with liquid than foam)
Initial shedding phase
Benefits stop if you stop using it
Best for: Anyone, especially if you do not want a prescription.
