Control GX is the first and only shampoo smart enough to gradually reduce greys by slowly bringing them back to their natural shade while it cleanses and conditions your hair. You get an extremely natural look - just by shampooing as you normally do. Just use it instead of your usual shampoo until you like what you see. Then use it in rotation with your usual shampoo to maintain the look you like. There's 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'll start to see a subtle reduction in the amount of gray.
