I would also suggest you co-wash more often. Try it for two weeks and track your results. Also, keep track of which products you're using and see if there's a product linked to your itchy, flaky days
Prior to following my curly hair routine, I'd do the traditional shampoo & condition 1-2 times per week. Now I co-wash 4-5 times a week and low-poo once a week. My scalp isn't dry and the flakiness I'd had for so long disappeared after week one.
