How does Rogaine (Minoxidil) work?
Rogaine (Minoxidil) reactivates or revitalizes shrunken hair follicles, increasing their size. While you continue to use Rogaine, follicles gain greater volume, their growing phases become longer, and they produce longer, thicker hairs. This is counter to what people who suffer with male pattern baldness experience. Usually, as males with MPB get older their hairs slowly become thinner as their follicles shrink. Rogaine works to counteract this.
