Here is the big thread on grabby vs slip. It mentions lots of products along the way. Post #2 mentions a few grabby leave ins.

Not a grabby leave in, but Ecostyler Krystal is a grabby gel that magically makes my hair clump. I also like BRHG. (a blog to help new wavies, go to the how do I get started page)
