Count me in with the rebellion
I do primarily use CG products, but I have a sulfate shampoo that will have to be pried out of my cold dead hands. I also have a handful of silicone products that I absolutely love.
I believe the key is to understand how these products work and make sure that we take steps to keep our hair moisturized. Even Lorraine Massey was okay with certain cones at one point-- One C used to contain amodimethicone.
