Results can vary from person to person. Studies have shown that a person's hair loss can continue if they stop using minoxidil products such as ScalpMED. As a result, ScalpMED recommends using its hair products continuously. ScalpMED writes that some products should be used twice a day. After 12 months of use, a person may be able to use ScalpMED once per day. Individuals should follow the company's instructions before starting treatment.
