I use all sorts of things, usually switching it up now and then cause after a while I tend to feel like things stop working as well on my hair, so I switch, and then switch back. My hair is super high maintenance though. I require really intense conditioners that would probably make most people's hair seem greasy for a week, and I can go through one bottle of shampoo in the same time I go through 3 bottles of conditioner.
I like Rusk shampoos alright, and all of the Ojon products except they've recently changed their packaging and I picked a conditioner that's different from the one I used to use by accident. I don't know if they still make it anymore )=. Then the FF stuff is nice every now and then, and I had good luck with this hemp stuff that comes in brightly colored containers.
Edit: I've used living proof... it didn't work for me )=
The most effective conditioner I've ever used is Terax, but it smells really strong in a chemical kind of way and makes me feel nervous. Sure used to make my hair soft and silky though...
