Abstract
A system and method for curling a lock of hair. A hair curling assembly contains a bi-stable ribbon spring. The ribbon spring is biased into a coiled configuration. The ribbon spring has positional stability in both its coiled configuration and its linear configuration. The ribbon spring is manipulated into its linear configuration within the hair curling assembly. The hair curling assembly is then positioned proximate the lock of hair to be curled. The ribbon spring is triggered back to its coiled configuration. The lock of hair winds with the ribbon spring into its coiled configuration, therein forming a curl in the lock of hair.
