I use it as a styler. I leave conditioner in as a leave-in...smother my hair in Curlkeeper and scrunch, scrunch, scrunch. I air dry about 10 minutes and then diffuse. That's why i LOVE it, it's so easy and leaves my hair feeling and looking awesome. Some do use it on top of, or under other products, everyone is different. Some find they need gel on top...some use it as a finisher. I tried all different combos at first and decided to try it on its own, best thing I ever did. HTH.
