These little roller clips don't look like they do much, but they are amazing. When I need volume on the days I don't wash my hair, I will put a few in my hair where I want volume and go on with my morning routine. By the time I'm ready to brush my hair, I take them out and WOW! The volume they give looks like I just had my hair done at the salon. Needless to say, I love them and highly recommend them!
