A significant factor in the product selection used
in the application of color is the client's hair:
Structure
The natural coloring pigment found in the cortex
layer of the hair is:
Melanin
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 hair:
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 predominant melanin that gives black and
brown color to hair is:
Eumelanin
Pheomelanin is the predominant melanin found
in what color hair?
Red
The pigment that lies under the natural hair color is:
Contributing pigment (under tone)
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
1
The highlight or the hue of color seen in
the hair is referred to as:
Tones
Colors that absorb more light and can look
darker than their actual level are:
Cool tones
Colors with a predominance of red are considered:
Warm Tones
Tones can be described as cool, warm, and:
Neutral
Artificial hair colors are developed from the
primary and secondary colors that form:
Base colors
A violet base color will deliver cool results
and will minimize unwanted:
Yellow tones
In hair color, a blue base color will provide
the coolest results and minimize( complementary):
Orange tones
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 provides the most
depth or darkness is:
Blue
Adding the primary color red to yellow colors
will cause them to appear:
Darker
Equal parts of red and blue mixed together
always make:
Violet
A color obtained by mixing equal parts
of two primary colors is a:
Secondary color
The secondary color created with an equal
combination of blue and yellow is:
Green
A color achieved by mixing equal parts of a
secondary color and its neighboring primary color
on the color wheel is a:
Tertiary color
Natural looking hair color is made up of a
combination of primary and:
Secondary colors
Primary and secondary colors that are
positioned opposite each on the color wheel are:
Complementary colors
All hair coloring products require a patch test
with the exception of:
Temporary colors
Hair coloring products fall into one
of how many categories?
Four
The chemical process involving the diffusion
of natural color pigment or artificial color from the hair is:
Hair lightening
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
Hair coloring products that partially penetrate the
hair shaft and stain the cuticle layer are:
Semipermanent colors
Demipermanent colors are also known as:
Deposit-only colors
The coloring products that are regarded as the
best for covering gray hair are:
Permanent hair coloring
Dye precursors that combine with hydrogen peroxide to form larger, permanent tint molecules are also referred to as:
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 creating a dull appearance contain:
Metallic salts
The most commonly used developer in hair color is:
Hydrogen peroxide
The measure of the potential oxidation of varying
strengths of hydrogen peroxide is called:
Volume
When less lightening is desired to enhance a client's
natural hair color, the standard volume used wth
permanent hair color is:
20 volume
Chemical compounds that lighten hair by dispersing,
dissolving, and decolorizing the natural pigment are:
Hair lighteners / Decolorization
In a one-step color service, 40 volume
hydrogen peroxide is used to provide:
Maximum lift
Hydrogen peroxide mixed into a lightener
formula creates a chemical process called:
Oxidation
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:

Hair Color Consultation

in a questionable condition should be required to sign a:
Release statement
When applying color using the brush-and-bowl method, the mixing bowl should be:
nonmetallic

prescribes that a predisposition test be given:
24 to 48 hours prior to application
To ensure successful results when performing hair
coloring services, the colorist must follow a:

A preliminary test performed to determine
how hair will react to a color formula is a(n):
Strand test
