Her whole site is full of great info on curly hair! If you didn't do a last sulfate wash, you probably have some kind of silicone buildup in your hair. This could be making it lose volume, because Cowashing can't get rid of silicones. the cones just coat your hair, making it weird and trapping moisture out (why your hair seems dry!!). It's important to do a last sulfate wash without any silicones in it, and then not use any products with cones after without clarifying. So before you change anything else, I'd try washing with a cone free sulfate shampoo and seeing if that makes a difference!
