When my hair is curly, I use Suave coconut conditioner. It's not a leave-in, but I use it like one. It is so light and really brings out my hair's curl. A lot of leave-ins are too heavy, but this one is just perfect. When it's straight, I love Frederick Fekkai Tech Shampoo & Conditioner and their Olive Oil glossing cream.
