What it is
Regulatory status: Nonprescription topical minoxidil products are FDA-regulated for labelled pattern-hair-loss populations and scalp areas; labels differ by concentration and sex.
Evidence basis: Human clinical evidence
Topical minoxidil is converted in hair follicles to minoxidil sulfate and can prolong the anagen growth phase and enlarge miniaturized follicles. Response varies, takes months and generally requires continued use to maintain gains.

Contraindications, interactions and clinical cautions from reviewed sources.
Common effects include scalp irritation, dryness and unwanted facial or body hair; temporary early shedding can occur. Stop and seek care for chest pain, faintness, rapid heartbeat, swelling or unexplained weight gain. Keep away from children and pets because minoxidil is highly toxic to cats, and avoid broken skin or unlabelled application sites.
