I found Giovanni conditioners to have pretty good slip, at least the ones that I tried. I wouldn't even bother with Curly Hair Solutions conditioner- it had no slip and no real moisturizing quality at all. I like several of their products, but not that one. Check the other Garnier Fructis conditioners. I know some have cones, but last I checked, there were two (including Pure Clean) that had no cones and two with only water soluble cones.
