Abstract
Abstract A method of applying hair in which individual suture loops are sewn into the scalp and wefts of hair are anchored between or along the sutures. The ends of each suture are secured together by intertwining the end portions and sewing a thin thread through and around the end portions. The suture is a thread made from a synthetic polymer which is impregnated or coated with an inert substance such polytetrafluoroethylene or a silicone. Alternatively, at least the portion of the suture which is embedded in the scalp and is made of any flexible material, is encased in a sleeve in which the suture may slide without irritating the subcutaneous area of the scalp.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
The method of applying hair wefts to a portion of a scalp which comprises inserting synthetic polymeric sutures below the dermis of the scalp leaving the ends of the sutures exposed above scalp, each suture being inserted once in the scalp; for each such suture, intertwining its exposed end portions together and sewing a thin thread through and around said end portions, comprising passing said thread through and around said interwinded suture at several spaced places between the points of entry and exit of the suture from the dermis and knotting said thread at each such place, and affixing hair wefts to the exposed portion of said sutures.
Claim 2
Independent Claim
108 words
The method of applying hair wefts to a portion of a scalp which comprises inserting synthetic polymeric sutures below the dermis of the scalp leaving the ends of the sutures exposed above scalp, each suture being inserted once in the scalp; for each such suture, intertwining its exposed end portions together and sewing a thin thread through and around said end portions, comprising passing said thread through and around said interwinded suture at several spaced places between the points of entry and exit of the suture from the dermis and knotting said thread at each such place, and affixing hair wefts to the exposed portion of said sutures.
Claim 3
Dependent Claim
19 words
The method of claim 1 comprising removing any excess suture substantially beyond that between said entry and exit point.
Claim 4
