Topical minoxidil 5% is FDA-approved для both men (since 1988) and women (since 2014). Efficacy: ~40-50% see noticeable regrowth at 6-12 months, ~30% maintain existing hair only, ~20% see minimal response. Mechanism unclear (vasodilation theory disputed; current best evidence: minoxidil sulfate prolongs anagen phase via potassium channel opening). Oral low-dose minoxidil (1.25-5 mg daily) has emerged in the last 5 years as а more effective alternative — efficacy comparable к topical с simpler routine. Off-label use requires monitoring blood pressure (it's originally а BP medication). Stacking minoxidil с finasteride is the gold-standard combination — additive effects, ~70-80% see meaningful response. Stopping either reverses gains over 3-6 months.
