Mechanism of action

Minoxidil opens ATP-sensitive potassium channels in vascular smooth muscle, increasing vasodilation and blood flow to the scalp. This enhanced perfusion delivers more oxygen and nutrients to hair follicles, stimulating them to transition from the telogen (resting) phase to the anagen (active growth) phase, thereby promoting hair regrowth and slowing hair loss.
