Getting Frustrated - Do I need a leave in?

I haven't had good luck with leave-ins. I am beginning to think its because it had either glycerin or loaded with proteins.

Someone has been kind enough to send me a [buylink=]KCCC[/buylink] sample, and I was wondering about [buylink=]KCKT[/buylink]. Does it work as a leave in well enough on its own? If not, what are other recommendations.

I tried KBB nectar as a leave in, but it only works as a rinse out for me.
