What is minoxidil?
Minoxidil - often sold under the brand name Rogaine - is a topical medication used to treat male pattern baldness and promote hair growth. Minoxidil is also effective in treating thinning hair in women. It is an over-the-counter medication that does not require a prescription.
Minoxidil is most effective when taken to slow the progress of pattern baldness. It is not generally used to treat other types of hair loss, like receding hairlines. If you are experiencing unexplained hair loss and do not have a family history of pattern baldness, contact your doctor. This could be a sign of a more serious medical condition beyond the scope of minoxidil.
