Abstract
Abstract An apparatus and method for isolating certain hair sections from other hair sections which are to be treated with hair waving, straightening, bleaching, or dyeing materials. In a hair waving application, each free end portion of a hair section to be protected from the waving solution is rolled onto a conventional curling rod. A sheet of fluid impermeable material is rolled onto the rod with the outer hair turns. A split sleeve is pressed onto the assembly of rolled up hair and sheet, and this seals the rolled up hair from intrusion of the waving solution. The inner end of the hair section can then be rolled onto the sleeve for treatment with the waving solution in the usual manner. In a hair straightening procedure the inner end of the hair section would not be wound onto the sleeve, but would instead be treated with the hair straightening solution. Hair frosting and reverse frosting procedures are performed by separating certain hair tresses and rolling them up in the manner described, thereby isolating such tresses from exposure to the hair frosting or reverse frosting materials.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
An apparatus for isolating sections of hair from hair treatment materials, said apparatus comprising: an elongated winding member on which a hair section is adapted to be wound; a sheet of material impermeable to said hair treatment materials and adapted to overlie said hair section for winding onto said winding member with said hair section; and a sealing member adapted for fitting onto said winding member in overlying relation to the wound up hair section and said sheet and operative to press upon and seal said hair section and said sheet from hair treatment materials.
Claim 2
Independent Claim
95 words
An apparatus for isolating sections of hair from hair treatment materials, said apparatus comprising: an elongated winding member on which a hair section is adapted to be wound; a sheet of material impermeable to said hair treatment materials and adapted to overlie said hair section for winding onto said winding member with said hair section; and a sealing member adapted for fitting onto said winding member in overlying relation to the wound up hair section and said sheet and operative to press upon and seal said hair section and said sheet from hair treatment materials.
Claim 3
Dependent Claim
38 words
An apparatus according to claim 1 wherein said sealing member is an elongated split sleeve made of resilient material whereby said sleeve is adapted to be sprung apart at the split for said fitting onto said winding member.
Claim 4
Dependent Claim
29 words
An apparatus according to claim 2 wherein the margins of said sleeve defining said split are each tapered to a thickness less than the wall thickness of said sleeve.
Claim 5
Dependent Claim
130 words
A hair treatment method characterized by isolation of portions of hair from the hair treatment materials, said method comprising the steps of: winding the free end portion of a hair section onto an elongated winding member; placing a sheet of material adjacent the mid portion of said hair section, said sheet of material being impermeable to the hair treatment material to be used; winding said mid portion of said hair section and said sheet together onto said winding member; placing sealing means on said winding member in overlying close fitting relation to the wound up end portion, mid portion and sheet for sealing the same against the hair treatment materials; repeating the foregoing steps on other hair sections to be isolated; and applying hair treatment materials to unisolated hair sections.
Claim 6
Dependent Claim
130 words
A hair treatment method characterized by isolation of portions of hair from the hair treatment materials, said method comprising the steps of: winding the free end portion of a hair section onto an elongated winding member; placing a sheet of material adjacent the mid portion of said hair section, said sheet of material being impermeable to the hair treatment material to be used; winding said mid portion of said hair section and said sheet together onto said winding member; placing sealing means on said winding member in overlying close fitting relation to the wound up end portion, mid portion and sheet for sealing the same against the hair treatment materials; repeating the foregoing steps on other hair sections to be isolated; and applying hair treatment materials to unisolated hair sections.
Claim 7
Dependent Claim
92 words
A hair treatment method according to claim 4 wherein the hair treatment method is for curling the scalp end portions of hair sections whose free end portions and mid portions were previously curled, and including the steps of: taking the scalp end portion of each hair section sealed by said sealing means and winding said scalp end portion upon said sealing means; retaining the wound up hair portions and sheet in wound condition on said winding member and sealing means; and applying hair curling material to the wound said scalp end portions.
Claim 8
Dependent Claim
59 words
A hair treatment method according to claim 4 wherein the hair treatment method is for straightening the scalp end portions of hair sections whose free end portions and mid portions were previously straightened, and including the steps of: taking the scalp end portion of each hair section sealed by said sealing means and applying hair straightening material to it.
Claim 9
Dependent Claim
171 words
A hair treatment method characterized by isolation of sections of hair from the hair treatment materials, said method comprising the steps of: weaving a tool in and out of a section of hair to provide adjacent first and second hair portions each constituted of alternate hair strands from said section; winding the free extremity of one of said first hair portions onto an elongated winding member; placing a sheet of material adjacent the scalp extremity of said first hair portion, said sheet of material being impermeable to the hair treatment material to be used; winding all of said first portion and said sheet together onto said winding member; placing sealing means on said winding member in overlying, close fitting relation to said wound up first portion and said sheet for sealing the same against the hair treatment materials, and simultaneously placing under said adjacent second hair portion a protective sheet; repeating the foregoing steps on other first and second hair portions; and applying hair treatment materials to said second hair portions.
Claim 10
Dependent Claim
171 words
A hair treatment method characterized by isolation of sections of hair from the hair treatment materials, said method comprising the steps of: weaving a tool in and out of a section of hair to provide adjacent first and second hair portions each constituted of alternate hair strands from said section; winding the free extremity of one of said first hair portions onto an elongated winding member; placing a sheet of material adjacent the scalp extremity of said first hair portion, said sheet of material being impermeable to the hair treatment material to be used; winding all of said first portion and said sheet together onto said winding member; placing sealing means on said winding member in overlying, close fitting relation to said wound up first portion and said sheet for sealing the same against the hair treatment materials, and simultaneously placing under said adjacent second hair portion a protective sheet; repeating the foregoing steps on other first and second hair portions; and applying hair treatment materials to said second hair portions.
Claim 11
Dependent Claim
30 words
A hair treatment method according to claim 7 wherein the hair treatment materials applied in said last step comprise bleaching materials whereby said hair treatment constitutes a hair frosting procedure.
Claim 12
Dependent Claim
30 words
A hair treatment method according to claim 7 wherein the hair treatment materials applied in said last step comprise dyeing materials whereby said hair treatment constitutes a reverse frosting procedure.
