Finasteride: cost, evidence, and the honest comparison
Finasteride reduces conversion of testosterone to DHT, the hormone most implicated in male pattern hair loss. It works by slowing the driver of the process, which is why consistency matters more than intensity.
What it's approved for
Male pattern hair loss at 1 mg; benign prostatic hyperplasia at 5 mg under a different brand. Not approved for women, and contraindicated in pregnancy.
What the research actually shows
Along with topical minoxidil, oral finasteride has the strongest evidence base in androgenetic alopecia — which is why our hair coverage puts natural alternatives beside it rather than in front of it.

Side effects, stated plainly
Sexual side effects are reported by a minority of users in trials and remain the subject of ongoing debate and research regarding persistence after discontinuation. This is a genuine prescriber conversation, not a footnote.
What it costs
Itemised generic pricing shows the medication in a $25-a-month subscription costs about $0.83 a month to make. Delivered cash prices run about $5 to $11 a month; subscriptions charge two to four times that, largely for the prescriber and auto-refill.

Common questions
What is the cheapest legitimate finasteride?
With a prescription in hand, flat-rate generic programmes and itemised-pricing pharmacies land around $5 to $11 a month delivered. Subscription brands bundle the prescriber, which is the honest trade-off — our table shows both.
