We started using Malibu C Swimmers Wellness Shampoo and Conditioner years and years ago for my son who loved his hair but hated the effect water polo and swim team had on it.  Swimmers Wellness Shampoo can change a swimmer's life!!! In the summer, all of us use it because we spend a lot of time in pools. It keeps my daughter's long waist-length hair full of moisture and free of the green tint and split ends. It's great! We love it! There is no comparison! I sang the praises of Malibu C at many a swim meet and water polo game and the Hard Water Wellness Shampoo works just as good for plain old hard water as well. The results are dramatic.
