My hair was so heavy and waxy feeling and I could not figure out why. I was doing some research and saw Malibu C Un-Do-Goo Shampoo and Hard Water Wellness Shampoo and used them from my local salon. SO much buildup came out of my hair, even after rinsing the shampoo out, I still had foam my hair was releasing from all of the buildup. I have well water and it's very hard and changes the color of my highlights. Malibu C Hard Water Wellness Shampoo really toned them down and now they look much more natural! My hair feels light and airy vs. waxy and heavy.
