Abstract
Abstract Hair is implanted in skin by stitching the hair in a manner to form loops which pass through the subcutaneous tissue and to leave a length of hair protruding from each point of entry of the hair into the skin and a length of hair protruding from each exit point of the hair from the skin. A length of hair from one such stitch is tied to a length of hair from a second such stitch. A novel frame comprising a plurality of spaced posts is suggested for holding loops of hair during the stitching. A novel needle has a diameter of about 0.003-0.006 inches and is provided with a hole for threading at its pointed end.

Claim 1
Independent Claim
113 words
A method of implanting hair in living skin which comprises the steps of: a. inserting a plurality of lengths of hair into living skin by passing lengths of hair into the skin at an entry point, then into the subcutaneous layer, and then out of the skin at an exit point to form a plurality of stitches and leave at least one length of hair protruding from each said entry and exit point; and b. tying knots close to the skin in a plurality of pairs of such hair lengths wherein each such knot joins a length of hair from one such stitch to a length of hair from a second such stitch.
Claim 2
Independent Claim
113 words
A method of implanting hair in living skin which comprises the steps of: a. inserting a plurality of lengths of hair into living skin by passing lengths of hair into the skin at an entry point, then into the subcutaneous layer, and then out of the skin at an exit point to form a plurality of stitches and leave at least one length of hair protruding from each said entry and exit point; and b. tying knots close to the skin in a plurality of pairs of such hair lengths wherein each such knot joins a length of hair from one such stitch to a length of hair from a second such stitch.
Claim 3
Dependent Claim
50 words
The method as defined in claim 1 including the step of forming said stitches as a part of a single continuous piece of hair, and following said stitching, cutting each length at a point intermediate the exit point of one stitch and the entry point of the next succeeding stitch.

Dependent Claim
25 words
The method as defined in claim 1 including the step of leaving only one length of hair protruding from each said entry and exit point.
Claim 5
Dependent Claim

The method as defined in claim 1 including the step of leaving two such lengths of hair protruding from each said entry and exit point.
Claim 6
Dependent Claim
61 words
The method as defined in claim 2 including the step of forming said stitches in a first substantially straight line and then in a second substantially straight line which is spaced from and substantially parallel to said first line, and wherein cut lengths of hair from said first line are, respectively, tied to cut lengths of hair from said second line.
Claim 7
Dependent Claim
20 words
The method as defined in claim 2 including the step of forming each stitch substantially parallel to the preceding stitch.
Claim 8
Dependent Claim
38 words
The method as defined in claim 2 including the prior step of forming loops of hair between successive stitches positioned in an orderly array such that individual hair can be more easily identified during the subsequent cutting thereof.
