Where do I find Flex Balsam & Protein Extra Body shampoo and conditioner?”
It is available through Amazon from third-party sellers. Just put “Flex shampoo” in the search box and choose the products you like. I, personally, get it from www.drugstore.com Drugstore.com has free shipping on orders over $49, and I purchase lots of other things, too, usually on a monthly basis. Their service is just as good as Amazon’s.
