I'm not totally CG (i tried to co wash once and absolutely hated it, so I just cut out cones) so I still use Lush's shampoos and conditioners. I'm not sure how different their SLS is compared (sometimes it's listed cetearyl alcohol & SLS) to others but it seems less harsh. As long as I don't use them twice in a row or a day apart, I do fine (I alternate with Burt's Bees). Although they FINALLY have a SLS free conditioner AND it's solid! It's called Big and I am in love with it. I didn't like the new gentle, non-stripping shampoo at all. I did like Fair Trade Honey shampoo, it's 50% honey which makes it really moisturizing and humectant.
