Abstract
Abstract A method of treating baldness by inserting strands of natural or synthetic hair into the scalp by suitable penetration instrument is disclosed. The method essentially involves passing a U-shaped loop of hair through the tissue beneath the scalp so that the base of the U protrudes therefrom and engaging the base of a second U-shaped strand with the first strand following which the first strand is pulled in the reverse direction so that the interengaged portions are disposed beneath the scalp in the insertion pathway. The method also includes the alternative of preforming a unit of two interlocking strands whose true ends have been joined chemically, thermally, mechanically, or electronically and inserting the units beneath the scalp with their opposed ends projecting from the penetration openings. The methods further contemplate applying a biodegradable tissue adhesive or tissue inert material at the point of interconnection of the strands or to join the free ends of the units and further contemplates the possible steps of applying similar material adjacent the perforation points where the strands were inserted into the scalp. Suitable apparatus, such as skewers having various strand carrying pockets and various configurations, are also disclosed to implement the method.
