How It Works
Minoxidil is a vasodilator, but how it regrows hair is not fully known. It may work by widening blood vessels in the scalp. This could improve blood flow to the hair follicles, stimulating hair growth.
How to Take It
Apply 1 mL of the solution directly to your scalp in the hair loss area. Do this two times a day using the dropper. Using more or using it more often will not make it work better. You must keep using it to increase and keep your hair regrowth, or your hair loss will start again.

What the FDA Data Shows for minoxidil topical
The FDA label for minoxidil topical (sold under brand names such as Rogaine) classifies it as an over-the-counter product in the Vasodilator (Hair Growth) class. This medicine is used to help regrow hair on the scalp. Labeling covers dosing, contraindications, and monitoring requirements derived from clinical trials.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. Interaction data is drawn directly from FDA-approved prescribing information. Acquisition-cost data is surveyed weekly by CMS and updated as manufacturers report changes.
Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions. This page summarizes public FDA data for educational purposes only and is not a substitute for professional medical advice — always consult a licensed healthcare provider before starting, stopping, or changing any medication.
