This isn't a leave-in, you wash it out. But it shampoo's and conditions! I have very thick, straight hair. If I use too much it makes it too soft to do anything with and gets greasier faster, and you have to you A LOT if you have a lot of hair. But if I use the right amount, my hair looks great! It's hard to find a happy medium. So I only use it every so often when my hair needs it.
