Abstract

A method of coloring selected hair shafts with a thixotropic hair treating material, while leaving adjacent hair shafts untreated, in which a thixotropic hair treating material is laid down onto a plurality of generally parallel spaced and non-overlapping areas running along the lay of the hair; and a method of touching up hair which has been so treated, after the roots have grown out.

Claims

1. The method of treating hair which comprises the steps of:

combing the hair to cause the hair shafts to lie in a natural parallel relationship;

defining a hair parting zone, consisting of the length of all the shafts of hair which have their roots within a closed, contiguous area of the person'"'"'s scalp;

said area having a generally rectangular shape;

subjecting the hair in said parting zone to tension so as to shape said hair into a laminar sheaf between the scalp and the place where tension is applied to the hair;

said laminar sheaf presenting an exterior face formed by adjacent exposed hair shafts, which exterior face is freely accessible to treatment;

applying thixotropic treating material to the exterior face of said hair treatment zone in a plurality of generally parallel spaced treated areas running along the lay of said hair;

said spaced treated areas being separated by untreated areas running along the lay of said hair;

said application of said thixotropic treating material being applied on the whole or parts of the length of the laminar sheath;

moving through the hair from a portion closer to the scalp to a portion more remote from the scalp, the thixotropic treating material being applied in a traverse along the lay of the hair.

2. The method of treating hair in accordance with claim 1 wherein said thixotropic treating material is applied simultaneously to the exterior face of said treatment zone in a plurality of generally parallel spaced treated areas running along the layer of said hair.

3. The method of treating hair which comprises the steps of:

combining the hair to cause the hair shafts to lie in a natural parallel relationship;

defining a hair parting zone, consisting of the length of all the shafts of hair which have their roots within a closed, contiguous and corresponding area of the person'"'"'s scalp;

said area having a generally rectangular shape;

said hair parting zone being defined by combing away any overlying hair not belonging to said hair parting zone;

subjecting the hair in said hair parting zone to tension so as to shape said hair into a laminar sheaf between the scalp and the place whereat tension is applied to said hair;

said laminar sheaf being unitary and presenting an exterior face formed by adjacent exposed hair shafts, which exterior face is freely accessible to treatment;

simultaneously applying treating material to the exterior face of said hair treatment zone only in a plurality of generally parallel spaced treated areas running along the lay of said hair;

said simultaneous application of said treating material initially and simultaneously being made to the exterior face of said hair treatment zone at the portion thereof closer to the scalp and finally and simultaneously being made to the portion thereof more remote from the scalp;

said simultaneous application of said treating material being made continuously during successively spaced intervals of time between the time of said simultaneous application initially and the time of said simultaneous application finally;

while the locus of said simultaneous application continuously and correspondingly moves from said portion thereof closer to the scalp to said portion thereof more remote from the scalp;

said simultaneously application of said treating material being made in a single transverse along the lay of said exterior face of said hair parting zone;

said simultaneous application of said treating material, under manual control, being made uniformly in said treated areas along and athwart the length of said single traverse; and

similarly and sequentially applying hair treating material to other hair parting zones, selected for treatment, until all selected hair parting zones have been treated.

4. The method of claim 3 in which said application of the treating material to the exterior face of the laminar sheaf extends from substantially the roots to the tips of the hair shafts.

5. The method of claim 3 in which said application of the treating material to the exterior face of the laminar sheaf extends from a region between the roots and the tips of the hair shafts substantially to the tips of said hair shafts.

6. The method of retouching the roots of hair which have been previously treated by the method of claim 3, and in which the roots have grown out, which comprises the steps of combing the hair to cause the strands to lie in a natural overlapping parallel relationship;

identifying the hair of said hair parting zone of claim 3 by its appearance;

combing away from said identified hair parting zone and overlying hair not belonging to said identified hair parting zone;

subjecting the hair in said hair parting zone to tension so as to shape said hair into a laminar sheaf between the scalp and the place whereat tension is applied to the hair;

said laminar sheaf being unitary and presenting an exterior face formed by adjacent exposed hair shafts, which exterior face is freely accessible to treatment;

touching up selected roots of the hair of said hair parting zone by applying treating material to the untreated portion of the exterior face of said laminar sheaf, which are in alignment with the treated areas left from the prior treatment.

7. The method of claim 3 in which the plurality of hair parting zones includes a portion only of the person'"'"'s hair.

8. The method of claim 3 in which the plurality of hair parting zones includes substantially all of a person'"'"'hair.

9. The method of claim 3 in which the plurality of hair parting zones is treated, seriatim, beginning at the nape and progressing towards the crown.

10. The method of claim 3 in which the plurality of hair parting zones is treated, seriatim, beginning at one zone and progressing to other zones, sidewise around the head.

11. The method of claim 3 in which said hair parting zone is further defined by isolating said hair parting zone with barrier material from any underlying skin and from any underlying hair not belonging to said hair parting zone.

12. The method of claim 3 which includes further defining each hair parting zone by separating at least one of said hair parting zones from the underlying hair not belonging to said one hair parting zone by establishing a barrier, impenetrable to said treating material, immediately beneath the hair of said hair parting zone and immediately above the underlying hair not belonging to said hair parting zone.

13. The method of treating hair which comprises the steps of:

combing the hair to cause the hair shafts to lie in a natural parallel relationship;

defining a hair parting zone, consisting of the length of all the shafts of hair which have their roots within a closed, contiguous area of the person'"'"'s scalp;

subjecting the hair in said parting zone to tension so as to shape said hair into a laminar sheaf between the scalp and the place where tension is applied to the hair;

said laminar sheaf presenting an exterior face formed by adjacent exposed hair shafts, which exterior face is freely accessible to treatment;

applying thixotropic treating material to the exterior face of said hair treatment zone in a plurality of generally parallel spaced treated areas running along the lay of said hair;

said spaced treated areas being separated by untreated areas running along the lay of said hair;

said application of said thixotropic treating material being applied on the whole or parts of the length of the laminar sheath;

moving through the hair from a portion closer to the scalp to a portion more remote from the scalp, the thixotropic treating material being applied in a traverse along the lay of the hair.
