The majority of the damage has been cut off of my hair, although it's very possible my hair is still high porosity. I've only straightened my hair once since the cut, I don't plan to do it very often. Any recommendations for protein treatments?

My scalp doesn't seem to mind sulfates, although the rest of my hair may not like them. I tried organix coconut milk shampoo that didn't have sulfates, my scalp didn't seem to like that at all. :/ Maybe it was just that shampoo, I'll definitely try another one.
