  • Spring hair comb
    Publication number: 20090065015
    Abstract: The spring hair comb consisted of the handle and the compression spring. The teeth of the comb are made of the coils of the compression spring. The thickness and spaces of the teeth depend on the size of the compression spring. This comb combs through hair smoothly with minimal friction and no pain to the scalp due to its round coils and its larger contact surface than the small and pointed teeth of other combs.
