The Color Wheel
These are pure or fundamental colors that cannot be created by combining other colors
What are primary colors
These tones reflect more light, making them look lighter than their actual level
What are warm tones?
These are non-oxidative colors that make only physical change- not chemical change on the hair shaft and have large pigment molecules that are deposited only on the cortex
What are temporary haircolors?
These come in clear and liquid forms; their pH is between 2.5 and 4.5; it's a combination of hydrogen peroxide and buffering agents; they can go by different names; they open the cuticle and shift the natural level.
What are developer or catalysts?
This is the two step process in which hair is decolorized with a lightener and then a toner is applied.
What is double-process haircoloring?
This is a system of understanding color relationships
What is the law of color?
These tones absorb more light, making them look deeper than their actual level
What are cool tones?
This type of haircolor is meant to deepen or change the tone of natural color; they are good to use when you are trying to avoid damage; they come in two forms (acidic and alkaline); you can freshen ends, tine highlights, blend gray, and perform corrections.
What are demipermanent haircolors?
This is an oxidizing agent that are in developers or catalysts.
What is hydrogen peroxide?
This is the visible line separating colored hair from new growth.
What is the line of demarcation?
Is a color obtained by mixing equal parts of two primary colors
What are secondary colors?
These tones are neither cool nor warm and can be tan or sandy.
What are neutral tones?
These are deposit only haircolors that are not mixed with a developer; can last several shampoos; depending on the hair's porosity and the pigment concentration; are great when doing fashion colors.
What are semipermanent haircolors?
This measures the concentration and strength of hydrogen peroxide.
What is volume?
This is a technique of coloring strands of hair darker than the natural color.
What is lowlighting?
Primary and secondary colors that are positioned directly opposite each other on the color wheel that neutralize each other
What are complementary colors?
This is the predominant tone of a color
What is base color?
This kind of haircolor can lighten and deposit color simultaneously; they are alkaline and are mixed with a developer; they can cover gray; they change the color of the hair in the cortex.
What are permanent haircolors?
This is added to haircolor to create alkalinity (raises the pH) to help with the oxidation process and help dye enter the cortex?
What is ammonia or ammonia substitute?
This is the process when your client presents with natural color and lightener is applied to the midshaft, ends, and scalp.
What is virgin lightener process?
Is an intermediate color achieved by mixing equal amounts of a secondary color and its neighboring primary color on the color wheel
What are tertiary colors?
What is cool tone?
This is also known as progressive haircolor; cause buildup on the hair shaft; they contain aniline derivatives and metallic salts.
What are metallic haircolors?
This is considered the "standard" volume of developer.
What is 20 volume?
This preliminary test determines how the hair will react to haircolor formula and how long the formula should be left on.
What is a strand test?
