You need to check the conditioner ingredients for silicones which coat the hair cause buildup if not properly removed. When I was new and cowashing every day I liked to use Aussie moist because it has amazing slip but by my second or third cowash my hair was dry and wouldn't absorb no matter how much moisture I put in it. The only remedy was to shampoo for a clean slate. I don't suggest anyone who cowashes as much as you do uses cones every time unless they plan to shampoo more than once a week. How often do you shampoo or clarify?
Do you use a leave in? Do you ever deep condition?
