Hmm..not sure about that but I'm extremely protein sensitive. Anything with protein, amino acids, even coconut and jojoba oils make my hair like straw. I've read up on it before and apparently, coconut and jojoba oils act like protein. I just avoid all of those ingredients all together because my hair will become a huge mess and take weeks to get back to normal. I've been trying to find protein free lo-poos and conditioners but it is pretty difficult.
Medium texture, medium porosity, and extremely protein sensitive.
Moderate CG? No harsh sulfates, limited 'cones.
