I've never heard of anyone using AOHR as a leave-in. I would guess that has something to do with the plastic feeling because it is so thick and rich.

Also, could it be possible that you used too much KCCC? The only time my hair ever feels coated from KCCC is if I use too much or if I went overboard with a gel on top of it.
