Hair Replacement Systems, often times called Hair Systems for Men, mens hairpiece or mens toupees is a wearable collection of human or synthetic hair, that is hand-tied into a mesh or light vinyl base, for the purpose of covering an area of the head that through chemotherapy, injury or heredity, has lost its source of hair. Once attached by glues, tapes or clips, the hair can be washed, cut, styled and trimmed, so that it blends naturally with the hair color of natural source.
