Simply amazing! I've tried other swimmers' shampoos/conditioners, and none compare to Malibu C Swimmers Wellness. I use it for all three of my daughters. They swim every day in the summer and their hair is soft and manageable thanks to Swimmers Wellness. Two of my girls have blond hair and Swimmers Wellness keeps their perfectly blond. They used to get a green tint to their hair from the pool water - no more now that we use Swimmers Wellness.
