I personally think it's way overpriced for what it is. I've never used it, but have heard very mixed reviews. I tried a very similar product (RenPure) and absolutely hated it. It obviously isn't CG. Yes, it would probably be beneficial for someone who is coming off of sulfates. But will it be beneficial from someone coming off already cowashing? That's for you try and decide. If you don't like it you can always go back to CG. There's no harm experimenting. Depends how your hair reacts to cones.
