Finasteride and minoxidil are the two hair-loss drugs with years of placebo-controlled trials behind them. Both work for many men with pattern hair loss, finasteride slightly better over a year, and they can be combined. Finasteride carries sexual and mood side-effect warnings you should read first. Supplements like biotin and saw palmetto are far weaker.
Keeps is a US telehealth service that sells generic finasteride and minoxidil after an online consult. Those are the two hair-loss drugs with strong trial evidence, and its prices are reasonable. The drugs are the point; the service adds convenience. Read the finasteride side-effect evidence first, and note it does not serve the UK.
