Topical Minoxidil
Hair-growth topical, often compounded with finasteride or other agents.
What it does
What Topical Minoxidil is and why doctors prescribe it.
Minoxidil is FDA-approved for androgenetic alopecia (male and female pattern hair loss). Compounded minoxidil is prescribed at strengths and combinations not in the OTC supply — for example, with topical finasteride, with retinoids, or at higher concentrations the prescribing doctor selects.
How it works
Mechanism in plain English.
Minoxidil's mechanism in hair growth involves potassium-channel opening in scalp follicles, vasodilation, and prolongation of the anagen (growth) phase. Topical finasteride combinations add 5-alpha-reductase inhibition at the scalp without systemic exposure of oral finasteride.
How long it's been studied
Research history.
Topical minoxidil received FDA approval for hair growth in 1988. Decades of clinical use and research inform contemporary prescribing. Compounded combinations are dispensed under 503A.
Dosing
Clinical context for the prescribing doctor.
Doctor-prescribed. Compounded minoxidil is commonly dispensed at 5%, 7%, or 10%, applied topically once or twice daily to dry scalp. Combination preparations include topical finasteride at 0.1–0.25%. Your doctor selects strength and combination.
This page is informational, not a dispensing aid. Topical Minoxidil is dispensed only on a patient-specific prescription written by a licensed doctor for an identified patient. Compounded drugs are not FDA-approved and should not be evaluated using branded-drug trial data. Availability varies by state and prescribed medication.
