I've been trying to get used to using leave-ins since my BC, and of all the ones I've tried (some of the ones you've mentioned), my favorite is SCurl activator no drip spray. The first day after a wash when applied to damp hair, it doesn't seem to do much. But if I spray it to dry hair the following day, my 4A/B hair turns out really nice and soft and feels oh so moisturized. It doesn't stay wet either, like my friend's hair seems to do. And my coils are very nicely defined. It's part of why I'm not sulking about the unplanned BC.
