ABSTRACT:
A method is disclosed for implanting hair into human skin comprising the steps of tieing a knot into a hair with the knot defining an interstice through which skin tissue may subsequently grow thereby anchoring the hair firmly in place, loading a needle by placing the hair knot in a hollow end of the needle and extending the hair from the knot through a notch formed in a surface of the needle end, inserting the loaded needle into the skin, and extracting the needle from the skin.
Apparatus is also disclosed for implanting hair having a bulbous end into human skin which apparatus comprises a tubular needle having a beveled end providing a pointed tip for piercing the skin and a notch formed in the beveled end through which the hair may extend with the bulbous hair end held within the tubular needle in engagement with an inner surface of the needle adjacent the beveled end notch.
A method is further described for determining an optimum size of an interstice defined by a knot on a hair to be implanted into human skin. The method comprises the steps of tieing a knot defining a spacial interstice of determined size in each of a plurality of hairs with the size of each knot interstice differing substantially from that of the interstices of the other knots; implanting each of the hair knots into the skin of a human; and subsequently exerting an extraction force on each hair and observing which hair required the greatest extraction force to be extracted without hair breakage.
