I don't remember that. I just skimmed it. What they say is "don't load it up." I have fine/low porosity hair and use all of the above. Just use them in minute amounts, except for protein. I do at least one PT a week and use a lot of products with protein.
On nc.com, they have something about low porosity hair and avoiding protein.
