The layer of the hair that gives the hair the majority of its strength and elasticity is the cortex. |
In individual hair strands, hair texture is determined by the diameter. |
If the cuticle is lifted, allowing the hair to take color quickly, the hair is said to have high porosity. |
Hair color levels are arranged on a scale from 1 to 10. |
Hair color tones can be described as warm, cool, or neutral. |
Warm tones that are described as sandy or tan are considered natural. |
Natural color will help balance orange tones in the hair. |
Pure or fundamental colors that cannot be created by combining other colors are called primary colors. |
The strongest and only primary color is blue. |
Red added to blue-based colors will cause them to appear lighter. |
A tertiary color is achieved by mixing a secondary color and its neighboring primary color. |
In traditional color theory, when all three primary colors are present in equal proportions, the resulting color is black or dark muddy gray depending on the saturation of the pigment. |
A primary and secondary color positioned directly opposite each other on the color wheel are considered complementary colors. |
Temporary haircolor pigment molecules do not penetrate the cuticle layer because they have large pigment. |
Traditional semipermanent haircolor only lasts four to six weeks depending on how frequently the hair is shampooed. |
Demipermanent haircolor is formulated to deposit but not lighten color. |
Permanent haircolor lightens and deposits color at the same time and in a single process because it is more alkaline than demipermanent colors and is usually mixed with a higher-volume developer. |
To provide maximum lift in a one-step color service, 40-volume peroxide is recommended. |
During the decolorizing process, natural hair can go through as many as ten stages. |
Overlapping color can cause breakage and create a line of demarcation. |
The three forms of hair lighteners are oil, powder, and cream. |
In weaving, selected strands are picked up from a narrow section of hair with a zigzag motion of the comb, and lightener or color is applied only to these strands. |
For clients with 80 to 100 percent gray, a blond shade haircolor is generally more flattering. |
To cover unpigmented hair on a salt-and-pepper head, the color formulation should be one to two levels lighter than the natural level. |
The process of treating grey or very resistant hair to allow for better penetration of color is known as pre-softening. |
When preforming a lightener retouch, new growth is lightened first. |
To produce a haircolor that looks natural, three primary colors must be present. |
The best way to obtain pale blond results is to use double-process blodning. |
When hair is violet, it is recommended that you use yellow to balance it. |
when hair is blue, it is recommended that you use orange to balance it. Selecting warm base colors creates brighter colors. |
Demipermanent haircolor deposits but does not lift color. |
During a haircolor consultation, you should look at the client directly. |
Traditional semipermanent, demipermanent, and permanent haircolor products that are used primarily on pre-lightened hair to achieve pale and delicate colors are toners. |
When preforming a patch test, the same color that will be used for the haircolor service, should be used. |
Hair that has previously received a color service will have a greater degree of porosity. |
Underlightened hair will appear to have more red, yellow, or orange than the intended color. |
The term tone, or hue, refers to the balance of color. |
Double-process application is a coloring technique that requires two separate procedures in which the hair is pre-lightened before the depositing color is applied. |
The melanin that gives blond and red colors to hair is called phenomelanin. |
The powdered persulfate salts added to the haircolor to increase its lightening ability are called activators. |
The technique called a soap cap refers to a combination of equal parts of a prepared permanent color mixture and shampoo used during the last five minutes of a haircolor service and worked through the hair to refresh the ends. |
Contributing pigment refers to varying degrees of warmth exposed during a permanent color or lightening process. |
Reverse highlighting is a technique of coloring strands of hair darker than the natural color. |
Level is a unit of measurement used to identify the lightness or darkness of a color. |
Predisposition test, also known as a patch test, identifies a possible allergy in a client. |
lightener is a chemical compound that lightens hair by dispersing, dissolving, and decolorizing the natural hair pigment. |
Volume measures the concentration and strength of hydrogen peroxide. |
Colors obtained from the leaves or bark of plants are called natural haircolors. |
A glaze is non-ammonia color that adds shine and tone to the hair. |
The term resistant means it is difficult for moisture or chemicals to penetrate the hair. |
Conditioner filler is used to recondition damaged, overly porous hair and equalize porosity so that the hair accepts the color evenly from strand to strand and from scalp to ends. |
Hydrogen peroxide developer is an oxidizing agent that, when mixed with an oxidation haircolor, supplies the necessary oxygen gas to develop the color molecules and create a change in natural hair color. |
A color filler is used to equalize porosity and deposit color in one application to provide a uniform contributing pigment on pre-lightened hair. |
Slicing is the process that involves taking a narrow, 1/8th inch (0.3 centimeter) section of hair by making a stright part at the scalp, positioning the hair over the foil, and applying lightening or color. |
The system for understanding color relationships is called the law of color. |
The term virgin application refers to the first time the hair is colored. |
Eumelanin lends black and brown colors to hair. |
A quick lightener, also known as an off-the-scalp lightener, is a powdered lightener. |
Haircolors containing metal salts that change hair color gradually by progressive buildup and exposure to hair, creating a dull, metallic appearance, are called progressive haircolors. |
A strand test is a test preformed to determine how the hair will react to the color formula and how long the formula should be left on the hair. |
When identifying natural levels for a haircolor service, your most valuable tool is the color wheel. |
The medium primary color is red. |

A non-oxidative toner contains no ammonia, requires no developer, and is gentle on the scalp and hair. |
Colors prepared by combing permanent haircolor, hydrogen peroxide, and shampoo are called highlighting shampoos. |
Coating compounds such as hair sprays, styling agents, and some conditioners can interfere with color penetration. |
A daily shampoo and blow-dry, and occasional permanent wave, or a few days in the pool can cause the artificial pigment in red hair to oxidize and fade. |
A creamy consistency provides the best control during the application of lightener as part of a double-process haircoloring service. |
Selecting warm base colors creates brighter colors. |
