My hair has trouble with polyquats, especially 4, 7 and 10. I'm told that they don't build up, but something stays on my hair and makes it difficult to absorb products. I get frizz when wet. Needed a strong surfactant to get my hair back to normal. Now, I stay away from them. The Set it Free has beeswax, so that could be coating your hair. And last of all, the Shea M Smoothie was just "heavy." Sat on my hair and coated it. IMHO, any of those products could be causing you problems.

I also don't understand why you say your hair is dry, but you're afraid to over condition it.

I use a lot of really rich products as my stylers. Never have to DT despite using a lot of protein. Are you doing any protein--PTs, etc.
