After many attempts of trying products to cover/rid the brassy streaks in my natural gray hair, my hairdresser finally tried your Malibu C Well Water products. After using the shampoo and conditioner, my hair was less brassy and dry. Then just yesterday, she tried the complete Malibu C Hard Water Wellness system (Hard Water Wellness Shampoo, Conditioner and Wellness Treatment) and saw amazing results! Finally the streaks are gone and my hair is shiny and manageable!
