An accidental discovery
Minoxidil emerged in the 1960s–70s as a potent vasodilator for hard-to-treat hypertension. Physicians saw patients growing hair — hypertrichosis — and researchers began investigating a topical application for hair loss.
Key milestones
| Year | Milestone (US) |
|---|---|
| 1979 | Oral Minoxidil approved for hypertension |
| 1988 | Topical 2% approved (prescription) for men |
| 1991 | Approval extended to women |
| 1996 | Over-the-counter status |
| 1997 | 5% solution for men OTC |
| 2006+ | 5% foam introduced; later labeled for women |
Where it stands today
Topical Minoxidil is sold worldwide by many brands, including FOLIGAIN, Rogaine®/Regaine® and store brands. Research continues on formulations, adjuncts and delivery. FOLIGAIN pairs Minoxidil products with cosmetic scalp and hair care such as TRIOXIDIL® formulas, which are cosmetics and not drug treatments.
