This hair lotion contains a combination of drugs with complementary modes of action. Firstly, 5% Minoxidil appears to work by gradually enlarging and lengthening hair follicles that that have been gradually shrinking. Secondly Azelaic acid, a potent inhibitor of 5-alpha-reductase has been included to prevent the formation of DHT, which prevents further hair loss by addressing the cause of the problem. Finally, Arginine is also included which helps increase nitric oxide production which is used by the hair follicle to maintain and promote new hair growth. This triple action lotion is more effective than the single ingredient treatments currently on the market. The lotion (1ml) must be used morning and night for 2 to 4 months to see evidence of new growth and up to 6 months to get a proper estimate of weather it will work for you. It must be continually used to be effective. Once treatment has ended the hair will return to its original state in about 3 months.
