I am not sure if I am sentive to proteins or not? I am not on CG, I wash my hair every day. Right now I am using a Natures Gate Poo. Basically what I think is happening with the condtioners is that they cause me frizz. I think it could be perhaps they are too much moisture? My hairdid real well with the Deva, I got great chunky curls but fly away frizz that does not seem to happen with other stuff.
