How does minoxidil work?

Oral minoxidil

Minoxidil works by promoting hair growth and slowing hair loss through several mechanisms:

Vasodilation: Minoxidil widens blood vessels, increasing blood flow to hair follicles. This enhanced blood supply delivers more oxygen and nutrients, stimulating hair growth.
Follicle Stimulation: Minoxidil extends the anagen (growth) phase of hair follicles, allowing them to produce longer and thicker hair strands. It also shortens the telogen (resting) phase, encouraging dormant hair follicles to enter the growth phase sooner.
Potassium Channels Activation: Minoxidil opens potassium channels in cells, which is believed to play a role in promoting hair follicle activity and growth.

Overall, these effects combine to enhance hair density, reduce hair shedding, and support the health and function of hair follicles.
