My grandchildren ages 7 and 9 we're swimming daily at summer camp. By the beginning of August they hair looked like straw. No shampoo or conditioner seemed to help. It always seemed like there was a build up in their hair. I saw this product mentioned on the NBC today show and immediately bought it. My daughter called to tell me it had worked wonders on the sun and chlorine damaged hair off my granddaughter and grandson. We will be buying this again!
