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

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
