My hair doesn't care for polyquats. So far, it's 4, 7 and 10 that I know. Now, I steer clear of any product that has them. I was told they can't possibly "build up;" however, I did have to use a lowpoo with a stronger surfactant to "remove them." Coco b didn't do it.

Other then the polyquats, there's nothing that "jumps" out at me. If that's not what it is the only other thing I can think of is all of the plant extracts--if you're protein sensitive. If your hair likes protein, it's the polyquats.
