My favorite leave in is It's A 10 Miracle Leave In. It's pricey, but it's the best leave in I have found thus far. Plus it helps with strengthening my hair as well.

I do also own Giovanni Direct Leave In as well. As that's what I had been using on and off before purchasing It's A10. I still do use it sometimes. It's an all natural product made with a lot of organic ingredients with in it. And, with this product a little bit really does go a long way.
