I've been using Malibu C Color Wellness Shampoo for the past 3 1/2 months and love how clean my hair is, and no buildup. Last weekend, my stylist redid my color and instead of using the Olaplex, she used a Malibu C Miracle Repair after the shampoo and it was awesome! My hair was far softer and shinier than when she used the Olaplex in a previous visit. And as of today, it has been almost five days since my hair was done and it STILL looks and feels great! I'm really pleased with Malibu C products!
