Personally, I find the Deva NoPoo very drying. It also has a polyquat. While they aren't supposed to build up, I have issues with them coating my hair and needing a strong surfactant to remove them.
I'd try clarifying with a strong surfactant, change to a different cleanser--and see if your YT Carrots works. You could also add some of the other YT Conditioners and rotate them for something a little different.
