Control GX is the first and only shampoo smart enough to gradually reduce shades of grey by slowly returning them to their natural shade as it cleanses and nourishes your hair. You get an extremely natural look - simply by regular shampooing. Simply use it instead of your usual shampoo until you like what you see. Then use it alternating with your usual shampoo to get the look you want. There has never been an easier way to control your grey. GET THE LOOK YOU WANT: Use Control GX as your daily shampoo, and after the first few washes you will begin to see a subtle reduction in the gray content. Continue to use until you reach the desired level of grey reduction (usually within 2 to 4 weeks). You can even control how gradually you get to your desired result by using it daily or every other day at the beginning. Stay with it: Once you have reached the desired level of grey reduction, you can reduce the frequency of application alternating with another shampoo. Generally, guys use it as a daily shampoo at the beginning, and when they are in "maintenance mode", they use it 3 to 4 times a week.
