I think there should be a hair length minimum stated when purchasing this product. With my hair, medium length, just past my shoulders and minimally layered, I had a difficult time getting all of the pieces to stay together. The directions say to roll the Wrap up-ward so the seam of the tool is in the back. I found that with my hair, it was best to wrap under with the seam in the front, that way I could pin and fix the pieces that fell out a little more easily. if your hair is anything like mine, this tool works, but you will definitely need pins and hair paste to keep everything together.
