Androgenetic alopecia is the most common of all types of hair loss. The severity of your hair loss is dependent upon certain genetic and hereditary factors. Testosterone is a hormone found primarily in males and can be seen in increasing amounts in females as they approach menopause. Testosterone itself does not have any negative effective on the hair follicles. However, when testosterone reaches the oil glands in the hair follicles, it comes in contact with the enzyme, 5-alpha-reductase. 5-alpha-reductase is directly responsible for the conversion of testosterone into dihydrotestosterone (DHT). This process is a precipitating factor for alopecia in both men and women. Newly formulated Advecia can help limit DHT production by blocking the action of 5-alpha-reductase. In addition, Advecia may increase nitric oxide production which can further promote new hair growth.
