I use conditioners with cones and even a couple deep conditioners with them and some without. I go about two weeks without using my sulfate free shampoo. I don't get build up from using the cones and I don't see any negative side effects, my hair is very soft and healthy. I use some non cone products and some with cones and it works well for me.
