How Rogaine (brand name is minoxidil) was discovered as a topical solution for hereditary hair loss is an interesting one. Originally introduced as a drug used for high blood pressure, side-effects of hair growth were found. Since the drug was not effective towards regulating the blood pressure, the FDA had approved it as a hair treatment for hair loss. It is now an over-the-counter topical solution that is available in a regular and stronger strength of 2 percent and 5 percent minoxidil respectively, and is available in Rogaine for Men, and Rogaine for Women.
What the drug does is to revitalize the hair follicles that had shrunken (causing thinning of hair and eventually hair loss), allowing the follicles to increase in size, although how it does that is unknown. It is also believed to increase the flow of blood towards the areas where the bald spots are, so hair growth is stimulated. With use of twice a day, the follicles can increase in size, and the growing phase for hair is extended.
For use, the solution needs to be applied on the balding area in the morning and at night. With Rogaine for men, 1 ml of the medication will need to be applied directly on the balding spot using a dropper, and then massaged thoroughly into the scalp. It can also come in foam form, which is applied onto the fingers, and then massaged into the problem area. As for Rogaine for Women, 1 ml of the 2 percent strength medication is applied with a dropper one time in the morning, and a second time at night.
So how effective is this medication? In a 16-week study program on male patients found that 85 percent of them had experienced some hair growth. On the other hand, in a 48-week study program on female patients, it was found that 60% of them had experienced hair growth by the 32nd week. Of the studies, only 6% of them experienced side effects like mild scalp itching and irritation. This indicates that the results may differ from person to person.
