These rollers are very small and compact. They are just perfect for travelling. I have very thin, fine hair and I can't seem to get these rollers to stay in my hair without falling out. I believe they would work well for someone who has a little more hair. This kit contains four small rollers that are too small and eight medium rollers that are just about the right size for someone with shoulder length hair; however, you will need about twice as many. If you have very long hair, this kit will not work for you.
