I am CG but when I used cones all I did was make sure I used a shampoo with that ingredient and that was how I got them out. I haven't used a sulfate shampoo in Lord knows how long. I do see curlies on here telling people they have to use a sulfate to remove silicones and buildup but I don't find that to be the case. There is an old naturally curly article listing all the silicones and what it takes to remove them. Should answer your questions.
