What is Finasteride?
Finasteride is a 5-alpha reductase inhibitor that blocks the conversion of testosterone to dihydrotestosterone (DHT) — the primary hormone responsible for male pattern baldness. FDA-approved at 1mg for hair loss (Propecia) and 5mg for benign prostatic hyperplasia. Generic finasteride is available online for a fraction of brand-name prices.
How it works
Taken once daily orally. Reduces scalp and serum DHT by approximately 60-70%. Works best for crown and mid-scalp hair loss; less effective for hairline recession. Takes 3-6 months to see initial results, 12 months for maximum benefit. Hair loss resumes within 6-12 months of stopping.
Clinics that offer finasteride online
What does finasteride cost online?
Generic oral finasteride starts at $17/mo online through Hims and Ro. Happy Head and Strut Health offer topical finasteride (often combined with minoxidil) at $40-80/mo. True annual cost ranges from $204/yr to $960/yr. Bundling with minoxidil is typically more effective than either alone.
Side effects and safety
Sexual side effects (reduced libido, erectile dysfunction, ejaculation changes) occur in approximately 2-4% of users — all clinically reversible in the vast majority after stopping. Topical finasteride reduces systemic DHT absorption and appears to have a lower rate of sexual side effects. Post-finasteride syndrome (persistent effects after stopping) is reported but rare.
Frequently asked questions
Does finasteride actually work for hair loss?
Yes — finasteride has strong clinical evidence. Studies show it stops progression in about 86% of men and produces visible regrowth in about 65% over two years. It is the only FDA-approved oral medication for male pattern baldness. Results require consistent daily use.
What is the difference between topical and oral finasteride?
Oral finasteride (1mg daily) reduces systemic and scalp DHT by ~60-70%. Topical finasteride delivers the drug directly to the scalp, reducing local DHT with less systemic absorption — lower blood levels mean fewer potential systemic side effects. Clinical efficacy appears comparable for scalp DHT reduction, though long-term head-to-head data is limited.
Can I get finasteride online without a prescription?
Finasteride is a prescription medication in the US. Online telehealth clinics (Hims, Ro, Happy Head, Keeps, Strut) provide a quick virtual consultation and prescription. The process typically takes 10-15 minutes online and medication ships within 3-5 business days.
Should I take finasteride with minoxidil?
Combining finasteride and minoxidil is significantly more effective than either alone — they work via different mechanisms (finasteride blocks DHT production; minoxidil extends the growth phase). Most hair loss clinics offer combination formulas. Happy Head specializes in custom compounded topical combinations.
