Minoxidil is a medication commonly used to treat hair loss, particularly in conditions like androgenetic alopecia or male and female pattern baldness. It works by stimulating hair follicles, promoting hair growth, and slowing down hair loss. Available in topical solutions and foams, minoxidil is applied directly to the scalp, making it easy to use at home. Originally developed as a treatment for high blood pressure, minoxidil was discovered to have the side effect of hair growth. Today, it is widely used and is available over-the-counter, making it accessible for those looking to improve their hair density and overall appearance.
