I agree with the recommendation for Knot Today (which I still think is the most amazing potion ever created), and recently I'm thrilled with Miss Jessie's Pillow Soft Curls, also sold at Target. The Pillow Soft says it's a styling lotion, but I use it as a leave-in at night after my wash, cover with my silk sleep scarf, and in the morning my hair has hardly any tangles. The Pillow Soft comes in a huge tube, and you only need a couple of tablespoons at a time, so it's long-lasting. (I go through Knot Today in a week sometimes).
