CHAPTER 16:HAIRCOLORING

regrowth; part of the hair shaft between the scalp and previously colored hair

Bleach/decolorizer, chemical compounds that lighten hair by dispersing, dissolving, and decolorizing the natural hair

primary and secondary color positioned directly opposite each other on the color wheel

Color achieved by mixing a secondary color and his neighboring primary color on the color wheel in equal amounts

recondition and equalize porosity on damaged hair; they condition, strengthen, help extend haircolor longevity

Color obtained by mixing equal parts of two primary colors

chart, circular, used as a tool that visually represents the relationships between colors

two-step blonding/double-process blonding coloring technique, recurring two separate procedures

System of understanding, color relationships

contain small, uncolored dyed that combine with hydrogen peroxide to form larger, permanent dye molecules with cortex

strong, fast-acting lighteners; powdered clay lighters that cannot be used directly on the scalp; oil, cream and powder

free-form technique or free-style hair painting, painting lightener( usually a powdered or clay-off-the-scalp lightener)

Common industry practice used to refresh permanent haircolor; combination of prepared permanent color mixture

tonality; refers to color balance

haircolor glaze, describes a hair color service that adds shine, warmth, and color to the hair

(One word), professional industry, coin term, referring to artificial hair, color, products, and services

takes 1/8 inch sections by making straight part at the scalp & separating select strands using tail comb going in & out

visible line separating colored hair from new growth

oxidizing agents/catalysts; have a pH between 2.5 and 4.5 when mixed with an oxidative haircolor, supplies, oxygen gas

H2O2, oxidizing agent when mixed with an oxidative hair, color supplies, necessary,oxygen gas to develop color molecules

lighters that can be used directly on the scout by mixing the Leitner with activators

equalize porosity and deposit color in 1 application; provide a uniform contributing pigment that supports desired hair

lighten and deposit color at the same time and in a single process because they are more alkaline than demipermanent

technique of coloring strands of hair, darker than the natural hair color

any technique that involves partial lightning/coloring, coloring hair strands, lighter than the natural color ,add depth

determine how the hair will react to the color formula and how long the formula should be left on the hair

hair treatment and product that contains oxidative dies in designed to add extreme shine to the hair

first step of double process haircoloring; used to lift or lighten the natural pigment before the toner application

measures the concentration and strength of hydrogen peroxide

permanent hair, color products mixed with a low volume developer, used on prelightened hair to achieve pale color

(two words)natural color of hair

boosters,protinators, or accelerators; powdered persulfate salts added to powder lightener to increase it lightening

Progressive haircolor; hair color contains metal salts that change hair color gradually by progressive buildup

The strength of color

Pure or fundamental colors(red, yellow, blue) that cannot be created by combining other colors

predominate tone of a color

Nonoxidative hair colors that make only a physical change not a chemical change on the hair shaft

formulated to deposit, but not lift (lighten) natural hair color; meant to deepen/change tone of natural color

undertone; varying degrees of warmth exposed during a permanent color or lightening process

techniques involves taking a narrow 1/8 of an inch sections by making a straight part at the scalp ,hair over the foil

Highlighting technique that involves coloring hair strands by slicing or weaving sections, placing them on foil

process that lightens or deposits color in the hair in a single application

measurement system that colorists used to determine the lightness or darkness of artificial and natural hair color

vegetable dye haircolors; colors, such as Henna, obtained from the leaves or bark of plants

deposit-only haircolor that is not mixed with a developer and is formulated to last through several shampoos
