A hair extension halo is a type of hairpiece worn around the head, designed to add volume and length to natural hair without the use of glue, clips, or tapes. It consists of a wire or band with extensions attached to it, and is often made with human or synthetic hair.
Hair extensions have been used for centuries, with ancient Egyptians using wigs and extensions made from human hair, wool, and vegetable fiber. In modern times, hair extensions became popular in the 1960s, when synthetic fibers were developed that could imitate the look and feel of human hair.
