Sounds like you have a Moisture problem.You need to do a deep treatment (no protein), and when you apply your moisturizer you need to apply a sealant over it too. Sealant for example can be natural Shea butter that you may see at the chinese Beauty Supply stores. It could be that you have too much protein in your hair which is making it dry. Also, you use tresemme which is usually not good for 4 type hair, and you need something that is creme based.Now using it for a detangler is fine but tresemme can cause major flakes and dryness. hope I helped a little bit?
