Abstract
A hair styling article comprises a spring strip having an open state and a closed state. In the open state the strip has a linear shape and high energy, while in the closed state it has a coiled shape and a low energy. The article also comprises a second strip which is flexible and approximately equal in length to the spring strip. The second strip is preferably a spring strip also. A method of styling hair using the article comprises placing a portion of the hair between the two strips while the strips are in their open states and then coiling them such that they release energy and enter low energy states corresponding to a coiled shape. In a preferred embodiment, the article comprises two strips of carbon spring steel flexibly attached to each other at one end and coated with a material having a textured surface to help prevent hair from slipping.
