What is the best (water-based) Leave-In Conditioner for African-American Natural Hair?

I already use Cantu Shea Butter leave in but I discovered that even that renowned leave in for Naturals has lanolin in it, which I was told that wasn't a good ingredient also and should be avoided. I would like to use a real, natural leave-in to out into my natural hair as it is very delicate and fine. There doesn't seem to be a leave in without all the unnecessary chemicals and artificial fillers... I looked up so many and most are just not good in the long run for many others.
