Women can use products with 5 percent minoxidil, such as Rogaine, to treat hair thinning or complete hair loss on the front of the scalp. One benefit of the 5 percent product is that it causes the hair to thicken, claims MedicineNet.
Minoxidil generally comes in two varieties: 2 percent and 5 percent, WebMD claims. The 5 percent is stronger because it has a higher concentration of minoxidil. A benefit of the 5 percent product is that it works 2.5 times as well as the 2 percent product.
Another use of minoxidil is to treat high blood pressure, according to Healthline. It should only be used under close supervision of a doctor.
