I live in a community where well water is the norm. I color my hair frequently, and after normal shampooing with other brand shampoos, I would lose shine and color, and the quality of my hair would look dry. After finding and using Malibu C Hard Water Wellness Shampoo and conditioner, my hair color is lasting normally. The texture and shine has improved! I am recommending the products to all of my customers, especially with our well water situation!
