That is my exact problem..the bane of my hair existence!! I don't have the answer either. I notice that I get a lot less of it if I have the time to do a Spritz & Condish before washing (which isn't often enough) and let my hair air dry. I get more the more I scrunch and if I diffuse. But the tradeoff is then that my roots are flatter
BRHG does seem to help a lot for me, along with LI in the winter only.
