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.

GLOSSARY
For the purpose of this disclosure, but consistant with the useage in the art, the following terms are defined:
Coloring: To lighten, as by bleach, or to darken, as by dye.
Strand: A bundle of individual hair shafts, all of which have roots in the same closed area of the scalp, with substantially every hair in that closed area included in the strand.
Laminar Sheaf: A special case of a strand in which the roots of the individual hair shafts are all located in a small and generally rectangular area of the scalp (1 to 5 centimeters wide by 6 to 12 centimeters long would be typical but not limiting) and in which all the hair of the laminar sheaf is combed out parallel and held under tension, as shown in FIGS. 3 and 4, so that the laminar sheaf along its length approximately retains its original width at the scalp but decreases in thickness from its original thickness at the scalp. The laminar sheaf is dense and not open; it substantially obstructs vision therethrough.
Parting: As a verb, the act of dividing the hair into portions constituting strands as defined herein. As a noun, often used in the art to describe a strand so formed. A parting can be a laminar sheaf, or it can be a coiled up bun, etc.
Face: The approximately planar exposed portions of the laminar sheaf. There is an inner face, which consists of those hair shafts which are normally closer to the scalp when the hair is in repose, and a corresponding outer face. Generally, when the hair stylist holds a sheaf from the lower part of the hair, the outer face is the nearer and visable one. But when holding up a sheaf of hear near the crown, the inner face may be the nearer and visable one. Either face may be the site of selective coloring.
Hair Treating Material: material which will color hair. It may be a solution, a visious liquid, a thixotropic liquid or a gel.
An applicator assembly for applying liquid product to the hair. The applicator assembly has an applicator that further base and multiple tines extending from the base. Opposite the tines, the base has a liquid distribution cavity. At least some of the tines have a tip at the end opposite the base, and may also have an enlarged fin section adjacent to the base. The enlarged fin sections extends to a shoulder portion located less than half way upward between the base and the tip of the tine. The tines may also have an aperature that allows fluid to be distributed from the cavity directly to the hair. The tip of the tine may be relatively flexible, while its enlarged fin section provides a more rigid lower portion.
A method for improving the dimensionality and fade resistance of oxidatively colored or lightened hair, a method for oxidatively coloring or lightening hair, a kit for use in practicing the method, and the related compositions.
