Hawaiian Silky works fantastic with KCCC for me as well! Another leave-in that works well for me to use instead of KCKT is As I Am Leave-in Conditioner. I can easily go through a bottle of KCKT in a week. The As I Am is actually more watery than KCKT, but I need way
less of it to get through all my hair. It does contain some glycerin, but my hair definitely gets moisture from it.
The As I Am Jelly is a decent alternative for the KCCC for me, and it's not at crunchy. (It doesn't hold as long, though.)
