A lot of people do a coconut oil pre-poo. I've been soaking my hair overnight in coconut oil before I low poo in the morning. I like it, especially since the dew points are getting really low here.

Tresemme Natural I find to be light, and it's great at detangling. A trim would definitely help you out. CJ Repair Me is also excellent if you haven't tried that out already.

I too have problem with polyquats and took me 2 sulfate washes to get it out. That stuff is gross.
