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
Dependent Claim 49 words
The method of claim 1 in which said suture to be inserted below the dermis is movably within a sleeve of an inert polymer and after said inserting of said suture and sleeve at least substantially removing said sleeve from the portions of said suture exposed above the scalp.
Claim 5
Dependent Claim 13 words
The method of claim 3 wherein said sleeve is a medically-compatible silicone polymer.
Claim 6
Dependent Claim 15 words
The method of claim 1 wherein the wefts comprise hair supported in strips of silicone.
