The exact way that Rogaine works is not known. It is possible that it dilates blood vessels in the scalp, which may improve hair follicle function and stimulate hair growth.
Rogaine is used to treat male pattern baldness in patients who are experiencing gradually thinning hair on the top of the head.
Rogaine may also be used for purposes other than those listed in this medication guide.
Do not use Rogaine if the skin on your scalp is damaged, irritated, or sunburned. This may allow more of the medication to be absorbed by your body, which could be dangerous.
Do not use Rogaine on any part of your body other than your scalp. Application to other body parts can be dangerous.
Do not use other topical products on your scalp during treatment with Rogaine, unless otherwise directed by your doctor.
