We live on well water and have sediment rich water. My 3-year-old daughter has blonde hair and it was looking as if I did a bayalage color on it, because the top was very dull and dark. I tried the Malibu C Hard Water Wellness Remedy on her and her hair was instantly brighter, and the color was back to being even from root to tip. Her hair looks amazing after the repair. I just ordered the Malibu C Hard Water Wellness Shampoo to try regularly to see if we can maintain the results! Thank you, Malibu C!
