I absolutely love Malibu C Un-Do-Goo Shampoo. It works like nothing else I have ever experienced before. I used it when I first tried to get rid of silicones and to my surprise, it really almost instantly got rid of what was realistically years of buildup. I still like to keep a bottle around for when I swim in a chlorine pool, or if I accidentally use a product that builds up. Thank youf for creating such a great product that is sulfate-free!
