Why hello there.
Maybe the 365 is too conditioning for you for this purpose. I don't think that slip or thickness is necessarily an indicator of how much moisture is being imparted to the hair. Glycerin and panthenol are moisture stuff.
It could also be adjustment.
But if you are mostly a 2, CG does say shampoo once in a while, just find some gentler stuff to use.
My own hair slurps up moisture and bangs its fork on the table for more, but I do have a lot of color treatment porosity. If you're a 2 with decently healthy hair, this product may be too moisturizing to co-wash with. And/or, you may want to use a non-sulfate shampoo every once in a while as per CG.
