The Topstyler has even been used by stylists in movies and TV shows to create luscious curls and waves. This system is supposed to be less damaging to your hair, and the shells hold your curls in place until the shells completely cool, giving your hair extra volume as well. The shells are heated after you plug the shell holder into an outlet. Once heated, you can wrap your hair using one of a few techniques, then allow the shells to cool completely on your hair.
"Using the TOPSTYLER couldn't be easier. It's just a few simple steps to get unbelievable curls, waves and volume. Simply wrap hair around fingers into the shape of a curl. Use small wraps for tight curls, or more loose wraps for larger curls or sexy volume. Then apply the C-Shell over the curl formed. Let hair cool inside the C-Shell to set the style for a short time, then allow hair to drop gently from the C-Shell revealing amazing curl and body. It's that simple!" - TopStyler.com
You can find the TopStyler for around $100 at ULTA, QVC, Macy's, Bed Bath and Beyond, Kohl's and other retailers that carry hair tools.
