I agree that you need to impart more moisture into your hair, but you need to maintain a certain level of protein so long as you have relaxed ends, or you'll start to get breakage at the line of demarcation. Why don't you buy 16oz of both the Dry Remedy and the Damage Remedy rather than going all out for just one? Who have two types of hair on your head, and they have different needs. And if you're going to flat iron your hair regularly, then you definitely need to make sure that you have sufficient protein in it, else you run the risk of breaking off the relaxed hair and damaging the natural hair.

Why don't you try alternating conditioners for a while and see how your hair responds, and go from there? Good luck.
