Abstract

Abstract This invention concerns a treatment which may be applied on practically all hair and which substantially improves the cosmetic properties thereof. More particularly, it contemplates a novel hair grooming aid to beautify hair, particularly living hair, which includes as a necessary ingredient a solid phase of finely divided fibrillatable polytetrafluoroethylene (hereinafter referred to as "PTFE") resin. The invention includes a process of grooming hair comprising applying the grooming aid to hair and brushing the hair at a temperature above the transition temperature at which PTFE fibriliates to form microscopic and submicroscopic fibers, in an amount sufficient to give the hair a natural appearance and to maintain its set for a long time.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 71 words
A method of grooming hair comprising: a. introducing particles of fibrillatable polytetrafluoroethylene resin into and throughout the hair, and b. fibrillating the resin by combing, brushing or rubbing at a temperature substantially above the temperature at which the resin fibrillates, but below the temperature at which the hair would be damaged, to form a network of fibers, invisible to the naked eye, throughout the hair effective to hold it in place.
Claim 2
Independent Claim 71 words
A method of grooming hair comprising: a. introducing particles of fibrillatable polytetrafluoroethylene resin into and throughout the hair, and b. fibrillating the resin by combing, brushing or rubbing at a temperature substantially above the temperature at which the resin fibrillates, but below the temperature at which the hair would be damaged, to form a network of fibers, invisible to the naked eye, throughout the hair effective to hold it in place.
Claim 3
Dependent Claim 16 words
The method of grooming according to claim 1 wherein the fibrillation temperature is above 20° C.
Claim 4
Dependent Claim 25 words
The method of grooming according to claim 2 wherein the resin is fibrillated at a temperature of between about 40° C. and about 60° C.
Claim 5
Dependent Claim 24 words
The method of claim 1 wherein the resin is present before fibrillation, in an excess of that required to hold the hair in place.
Claim 6
Dependent Claim 23 words
The method of claim 4 wherein the resin, after fibrillation, is present in an amount of less than 1% by weight of hair.
Claim 7
Dependent Claim 22 words
The method of claim 4 wherein the resin is present in an effective amount of less than 0.05% by weight of hair.
