Minoxidil is used as a hair treatment medication. Originally, it was a method to treat blood pressure. But both patients and doctors noticed a side effect – a growth of hair. After an intense research, scientists determined that minoxidil would be an excellent way to deal with baldness. Moreover, men started applying it to their beard, and the results left them extremely pleased. Now, almost everyone can grow a bushy beard with a little bit of help from minoxidil.

Minoxidil is believed to increase the amount of blood flow (and thus nutrients) to the hair follicles as well as promoting the production of hair material. However, the mechanism of action of minoxidil is only poorly understood presently.
