Abstract: A hair frosting device consisting of a container which is hinged on one side and snapped latched on the other so that it can be opened for placing a strand of hair therein. An opening at one end thereof is notched on one part of the container with cooperating notches on the other part for pulling the hair strand through and positioning it after which the container is filled with a hair treating liquid and closed. This allows the isolated treatment of one or more strands of hair without the problem of treating adjacent strands which are not desired to be treated.
