The only thing I've tried is the deep cond you mentioned and I really like it too. The on.y negative foe me was that I didn't get immediate slip with this and when I did get slip, it was after adding oil. It really works well as a dc though.
My hair: thick, medium/coarse, high porosity in the crown naturally, normal porosity everywhere else.
