Minoxidil is effective at treating hair loss. In some, but not all, men, it may cause hair regrowth.
Common side effects include irritation and itching of the scalp where the medication is applied.
The exact mechanism of action of minoxidil is not completely understood but it is known to increase blood flow, lengthen the growing phase of hair follicles (anagen), and increase the size of hair follicles.
