Minoxidil, otherwise known as Rogaine, is a topical medication that is used to increase hair growth. Minoxidil has been proven to stimulate hair growth on the bald spot located on the back of men's heads.

How to use Minoxidil
This medication must be applied to the scalp at least twice a day for four months, once in the morning and once again in the evening, before any noticeable change appears. It must be applied to a dry scalp and left untouched for four hours in order to ensure proper absorption (no swimming, no shampooing, etc.). Once you notice results, you must continue to use the product to maintain hair growth.

The negative side to Minoxidil
- Minoxidil is not as effective on patients who are old, have large areas of baldness or who have been bald for a long period of time.
- The oral form of minoxidil can increase heart rate, cause fluid retention and weight gain and can cause a decrease in blood pressure. Therefore, patients with significant coronary problems should not use this medication.
- The high alcohol base in Minoxidil can cause irritation to the eyes.
- The side effects of Minoxidil include skin irritation, hives, itchiness, swelling and sensitivity.
- The use of Minoxidil may cause a temporary increase in hair loss during the first few weeks of treatment. This shedding period, however, is a natural part of the hair growth cycle.

Minoxidil can only be purchased by prescription.
