Overview
Hair loss treatment with proven medications has never been more accessible. Finasteride (blocks DHT, the primary driver of male pattern baldness) and minoxidil (extends the growth phase of hair follicles) are the two FDA-approved treatments with the strongest evidence base. Online clinics have made prescription-strength formulations available at a fraction of in-person dermatology prices.
Top Hair Loss Treatment clinics: quick comparison
What you need to know
Finasteride vs minoxidil: finasteride addresses the hormonal cause of hair loss; minoxidil stimulates growth. Most effective when combined.
Topical vs oral: topical finasteride reduces systemic DHT absorption and sexual side effects compared to oral. Available at Happy Head, Strut, and others.
Ketoconazole shampoo: anti-fungal that also reduces scalp DHT. Keeps is the only major clinic that includes it in a standard plan.
Dutasteride: stronger than finasteride, inhibits more DHT pathways. Available at Happy Head. Not FDA-approved for hair loss but prescribed off-label.
Women's hair loss: different medications than men (spironolactone, minoxidil). Hers and Happy Head have specific women's protocols.

Frequently asked questions
Does finasteride actually work?
Yes. Finasteride has strong clinical evidence for male pattern baldness (androgenetic alopecia). Studies show it stops progression in ~86% of men and produces regrowth in ~65% over two years. It works by blocking the conversion of testosterone to DHT, which shrinks hair follicles. Results take 3–6 months to become visible, and maximum benefit at 12 months. It only works while you're taking it — stopping leads to resumption of hair loss within 6–12 months.
What are finasteride's side effects?
Sexual side effects (reduced libido, erectile dysfunction, ejaculation changes) occur in approximately 2–4% of men on oral finasteride at the 1mg dose. These are reversible in almost all cases after stopping. Topical finasteride produces significantly lower systemic DHT reduction (by design) and appears to have a lower rate of sexual side effects, though data is still emerging. Post-finasteride syndrome (persistent side effects after stopping) is reported but its prevalence and mechanism remain debated.
How long does it take to see results?
Hair loss stabilization (stopping further loss) can be seen within 3 months. Visible regrowth typically takes 6–12 months. If you haven't seen results after 12 months of consistent use, the treatment may not work for your specific pattern of loss. Consistency is critical — skipping doses significantly reduces effectiveness.
