I know L'Oreal has some sulfate free shampoos. The evercurl forumla is sulfate free, but I think it has some cones. However the shampoo should be sufficient to avoid cone buildup. That formula also has a cleansing conditioner that appears to be cone free for the US version (blue bottle with a pump on top) if you prefer that over using a low poo and separate rinse out conditioner. I know the Suave Naturals conditioners are usually cone free, so you could use that for your rinse out and even a little bit for leave in since it's so light.
