How does Minoxidil work?

Minoxidil works as a vasodilator, widening blood vessels in your scalp to encourage blood flow to the area.
This encourages more nutrients and oxygen to reach the scalp, helping to support hair follicles to return to health. In this way, Minoxidil works to “reset” the life cycle of your follicles, meaning that their growth phase is longer and the resulting hair thicker and healthier.

This, of course, means hair regrowth.
