Minoxidil Drug Information
Available without a prescription, minoxidil (Rogaine®) is a medicine used to treat androgenetic alopecia, commonly called male or female pattern hair loss. This medication comes in the form of a liquid solution or foam, and is applied to the affected areas of the scalp twice daily. It is only approved for use in adults age 18 and older.
Although it is not exactly clear how minoxidil works, it is thought to cause hair growth by stimulating resting hair follicles to enter into an active growth phase.
Most people tolerate this medicine well; however, it can cause side effects, including unwanted facial hair and a dry, itchy, and flaky scalp. Also, make sure your healthcare provider has information about other drugs you are taking before using minoxidil.
