Minoxidil is one of the most popular types of hair loss treatments. When this drug was originally created, researchers intended it to be a blood pressure medication. Their subjects, however, ended up with an unexpected side effect: hair growth!

Researchers couldn’t resist exploring the unexpected side effect minoxidil had caused. By the 1980s, large-scale clinical trials were able to confirm the safety and effectiveness of this drug. Although it’s not fully established, minoxidil is thought to work by increasing blood flow to your scalp. This can help stimulate the follicles in your scalp and prompt them to produce more hair.

Minoxidil has become available in different concentrations (2 and 5 percent) and can be purchased as either a serum or a foam. It’s also sometimes administered in conjunction with other hair loss treatments, like finasteride or microneedling.
