After moving to a house with well water, my natural blonde hair with added blonde highlights turned dull, brassy and straw-like. My hairstylist even asked me what I was doing to my hair because the color seemed so off. She gave me a Malibu MakeOver at the salon (which did the trick), however; my hair kept reverting back to a horrible brassy blonde. I began using the Malibu C Hard Water Wellness Collection Kit (shampoo, conditioner and treatment) and my hair is back to its old self...great color, texture and manageability. I use the Hard Water Wellness Shampoo and Conditioner daily and the Wellness Remedy treatment once per month.
