By undergoing a first step for passing a hook portion 1a of a hair-implanting needle 1 from the surface 2a to the back 2b of a wig base 2 and passing the hook portion back onto the surface at another position, a second step for catching a loop 3b formed at the turning position of hair 3 folded, a third step for pulling the loop 3b out of the wig base 2 in a state wherein the hair is caught by the hair-implanting needle 1, a fourth step for catching one side 3a of the hair with the hook portion 1a, a fifth step for pulling the hair-implanting needle out of the loop 3b in this state, a sixth step for forming a knot by pulling one side 3a of the hair while holding the other side 3b, and a seventh step for moving the knot 3e to the back 2b of the wig base by pulling the other side 3b of the hair while holding the one side 3a of the hair, a wig wherein the knot 3e of the hair 3 is on the back 2b of the wig base is produced.

A hair material for a wig is preliminarily curled and then bound to a wig base to thereby orient the curled hair in a definite direction. A folded part (10c) of a hair material (10) is penetrated from one side of a filament (15) to the other side under a wig base (12) so that a first loop (17) is formed in the inner side of the folded part (10c). A curved part (10d) is inserted through the first loop (17) so that a second loop (19) is formed in the inner side of the curved part (10d). A part (10b) of the hair material is inserted through the second loop (19). Next, the hair material parts (10a, 10b) are pulled in directions opposite to each other and tied with the filament (15) at (20). Thus, the hair material (10) is bound to the filament (15).

By determining the total tying amount of the hair to be short hair 3 and long hair 4 to a wig base 2 to a pre-determined density, and further determining the tying ratio of short and long hairs 3 and 4 to the pre-determined ratio, after tying long hair to be short hair first to a wig base 2 in said pre-determined ratio, and cutting to a pre-determined length to make short hair 3, and next tying long hair to be long hair 4 among the tied short hair 3, and cutting to a pre-determined length to make long hair 4, short and long hairs 3 and 4 can be tied in the pre-determined hair amount, and moreover, short and long hairs 3 and 4 can be tied by controlling to the pre-determined mixing ratio, thereby a wig of a rich bulkiness owing to standing of long hair 4 supported by short hair 3 can be obtained.

In a wig 10 comprising a wig base 11 and hairs 12 tied thereon, the wig base 11 is made with a base member 14 of artificial skin and a second base member 15 made of a net member provided on its backside, hairs 12 are knotted to the second base member 15, and inserted and pulled out from the lower side of the first artificial skin base member 14 to the surface side, thereby a wig 10 is obtained in which a needle foot is not formed on the backside of a wig base, and which has such natural appearance as if the hair 12 grows from skin pores, and excels in appearance.

An apparatus comprises means for supplying artificial hairs (30) onto one surface of a base (11) and a needle (41) movable in a direction perpendicular to the surface of the base (11). The needle (41) pierces the base (11) in a stretched condition to draw out the artificial hairs (30) toward the opposite surface of the base (11). The base (11) is supplied to a top surface of a conveyor table (21) movable on a two-dimensional plane in perpendicular directions, movement thereof being controlled to be done at a predetermined pitch in a predetermined order, so that the base becomes stretched. In this stretched condition, the artificial hairs are transplanted. After hair-transplantation, the stretched condition is released. This prevents needle holes, formed by hair-transplantation, from being connected with each other to form a continuous slit.
