According to the American Hair Loss Association, two clinically proven hair loss treatments are finasteroid, an orally ingested medication which has proven to significantly reduce the progression of hair loss, and minoxidill, a proven male pattern treatment for those that do not respond to finasteroid. However surgical hair restoration of follicle grafts are proven to be the most effective for those with significant hair loss. The hair is transplanted by harvesting hair from the back of the scalp, which is then transplanted into the areas of baldness.
