Abstract
A method for joining hair includes the steps of winding joining hair around and loosely knotting the same to a rod member, which is provided on one end thereof with a loop portion having flexibility, unit by unit, at predetermined intervals, withdrawing the joining hair wound around and loosely knotted to the rod member, unit by unit, through the loop portion after a strand of natural hair on the scalp of a person's head is inserted into the loop portion, and tightly knotting a knot portion of the joining hair thus withdrawn, by pulling opposite ends of the joining hair so that the joining hair is tied to the natural hair strand at the knot portion. A hair-joining device used in this method comprises a rod member provided on one end thereof with a loop portion having flexibility, and the rod member having joining hair which is wound around and loosely knotted to the rod member, unit by unit, at predetermined intervals. It is very advantageous if the hair-joining device comprises an inner rod member provided on one end thereof with a loop portion, the inner rod member having joining hair which is wound around and loosely knotted to the inner rod member, unit by unit, at predetermined intervals, and an outer cylindrical member for receiving therein the inner rod member having the joining hair. According to the invention, joining hair can be firmly tied to natural hair on the scalp of a person's head in an efficient manner, using a loop portion normally having a constant dimension.
