There was a thread on this a while ago and I think it honestly depends on the person and how prone they are to buildup. You should try the gentlest cleanser available first but if you're still getting buildup just go a step up. Maybe graduate from cocobetaine all the way up to say olefin sulfoconate or something. I have TJ's Tea Tree Tingle shampoo to clarify and even though I haven't tried any products with silicones since using it I'm next to certain that stuff would get it out.
