We moved three weeks ago, and my hair immediately changed due to showering with well water. We purchase a water test kit and it tested off the scale for hardness! My previously-well-behaved hair became tangly and crunchy, and my blonde highlights dulled. I tried removing the deposits with baking soda, apple cider vinegar and multiple salon-brand clarifying shampoos, but had no luck. After just one Malibu C Hard Water Wellness Treatment, my hair's vitality was restored! The bounce was back, it was shiny again, it held a curl again, and I no longer needed half a bottle of detangler to get a brush through it. I will continue to use this product on a weekly basis to maintain the results. Thank you!
