I second the ABBA Nourishing Leave-in! It's my favorite! I find it a little easier to distribute than the Elucence, which would probably be my second choice.

In desperation (running low on ABBA), I've even used Suave Coconut as a leave-in. Not as good as the ABBA, though, but it worked for a few days.
3b/c normally, 3a/b in the winter
