Minoxidil is an antihypertensive vasodilator medication. It also slows or stops hair loss and promotes hair regrowth in some people. Now off-patent, it is available over-the-counter for the treatment of androgenic alopecia.
Minoxidil, applied topically, is widely used for the treatment of hair loss. It is effective in helping promote hair growth in both males and females with androgenic alopecia.About 40% of men experience hair regrowth after 3-6 months. Minoxidil must be used indefinitely for continued support of existing hair follicles and the maintenance of any experienced hair regrowth. It is the only topical product that is FDA approved for androgenic hair loss.Treatments usually include a 5% concentration solution that is designed for men, and a 2% concentration solution for women.
The drug is available in the United Kingdom over-the-counter.
Its effect in people with alopecia areata is unclear.
Mechanism of action
The mechanism by which minoxidil promotes hair growth is not fully understood. Minoxidil is a potassium channel opener, causing hyperpolarization of cell membranes. Minoxidil is less effective when there is a large area of hair loss. In addition, its effectiveness has largely been demonstrated in younger men who have experienced hair loss for less than 5 years. Minoxidil use is indicated for central (vertex) hair loss only. Minoxidil is also a vasodilator.Hypothetically, by widening blood vessels and opening potassium channels, it allows more oxygen, blood, and nutrients to the follicle. This may cause follicles in the telogen phase to shed, which are then replaced by thicker hairs in a new anagen phase. Minoxidil is a pro-drug activated by sulfation via the sulfotransferase (SULT1A1). Several studies demonstrated that the activity of sulfotransferase in hair follicles predict minoxidil response in the treatment of hair loss.Two clinical studies are being conducted in the US for a medical device that may allow patients to determine if they are likely to fail minoxidil therapy.
