Deck 4 Flashcards
The natural coloring pigment found in the cortex layer of the hair is:
melanin
Hair texture is determined by the diameter of individual hair:
strands
Fine hair takes color faster and can look darker because the melanin granules are grouped:
more tightly
The hair type with a large diameter that can take longer to process hair color is:
coarse-textured hair
The ability of the hair to absorb liquids is referred to as:
porosity
When the cuticle of the hair is lifted and the hair is overly porous and absorbs color quickly, the hair porosity is defined as:
high
The melanin that gives black and brown color to hair is:
eumelanin
The system used by colorists to analyze the lightness or darkness of a hair color is:
the level system
The darkest hair colors in the level system are identified as being a level:
1
The system used for understanding color relationships is the:
law of color
Fundamental or pure colors that cannot be achieved from a mixture are:
primary colors
The primary color that brings depth or darkness to any color is:
blue
A color obtained by mixing equal parts of two primary colors is a:
secondary
A color achieved by mixing equal parts of a secondary color and its neighboring primary color on the color wheel is a:
tertiary color
Primary and secondary colors that are positioned opposite each on the color wheel are:
complementary colors
The hue or balance of color seen in the hair is referred to as:
tone
Tones can be described as cool, warm, or:
neutral
Colors that can look deeper than their actual level are:
cool tones
Neutral base colors are often used to cover:
gray hair
All hair coloring products require a patch test with the exception of:
temporary colors
As part of their composition, all permanent hair coloring products and lighteners contain both a developer and a(n):
alkalizing ingredient
Coloring products that have a coating action on the hair and are removed by shampooing are:
temporary colors
Demipermanent colors are also known as:
no-lift deposit-only colors
The coloring products that are regarded as the best for covering gray hair are:
permanent haircoloring
Dye precursors that combine with hydrogen peroxide to form larger, permanent dye molecules are called:
aniline derivatives
Natural, vegetable, and metallic hair colors are also known as:
gradual colors
Hair coloring products that change color gradually by progressive buildup and exposure to air contain:
metal salts
The most commonly used developer in hair color is:
hydrogen peroxide
The standard volume of hydrogen peroxide used to achieve most results with permanent hair color is:
20 volume
Chemical compounds that lighten hair by dispersing, dissolving, and decolorizing the natural pigment are:
hair lighteners
The process where the hair is prelightened and then toned is:
double-process application
Decolorizing the hair’s natural pigment allows the colorist to create the exact degree of:
contributing pigment
Hair coloring products that are used primarily on prelightened hair to achieve pale and delicate colors are:
toners
During the process of decolorizing, natural hair can go through as many as:
10 stages
The most critical part of a color service is the:
haircolor consultation
Clients with hair in questionable condition who request chemical services should be required to sign a:
release statement
When applying color using the brush-and-bowl method, the mixing bowl should be:
nonmetallic
Before performing a coloring service with an aniline derivative product, the client must have a(n):
patch test
The U.S. Federal Food, Drug and Cosmetic Act prescribes that a predisposition test be given:
24 to 48 hours prior to application
A predisposition test is generally conducted behind the ear or:
inside the elbow
The process that lightens hair and deposits color in one application is a:
single-process hair coloring
Examples of single-process permanent coloring applications are virgin color applications and:
color retouch applications
Overlapping hair color on previously tinted hair can cause breakage and create a visible line of:
demarcation
When applying color for a single-process retouch application, the color should be applied to the new growth using:
1/4-inch partings
Lighteners that have a thicker consistency and give more control during scalp application are:
cream lighteners
Powdered persulfate salts added to hair color to increase its lightening ability are:
activators
The part of the hair shaft between the scalp and the hair that has been previously colored is the:
new growth
The coloring technique that involves coloring some strands of hair lighter than the natural color is:
highlighting
The technique of coloring strands of hair darker than the natural color is:
lowlighting
In the weaving technique, selected strands are picked up from a narrow section of hair with a:
zigzag motion
The technique using a free-form of painting hair lightener directly on clean, styled hair is:
baliage
The process of treating gray or very resistant hair to allow for better penetration of color is:
presoftening
You should NEVER apply hair color to a client if the scalp has any obvious signs of:
abrasions
