Hair Coloring

Primary colors

colors that cannot be achieved from a mixture of other colors

Tertiary color

mixing equal amounts of a secondary color and its neighboring primary color on the color wheel

Complementary colors

on the color wheel, a primary and secondary color opposite each other

Secondary color

mixing equal amounts of two primary colors yields this kind of color

The colors blue, red and yellow are

primary colors

Violet, orange and green

the colors known as secondary colors

The color green is made up of equal amounts of

yellow and blue

Red and green

an example of complementary colors

Of the different hair textures, fine hair

takes color faster

Hair that takes color quickly and also tends to fade quickly generally has

high porosity

If a client's hair feels smooth when you test it between your fingers, it has

low porosity

The black and brown color in hair comes from

eumelanin

The lightness or darkness of color is measured in terms of

level

The term intensity is used to refer to

the strength of a color tone

A color's warmth or coolness is called

tone

Temporary haircolor

The type of hair color that has only a coating action on the hair

Semi-permanent color molecules are

smaller than temporary color molecules

Demi-permanent haircolors, which darken the natural hair color, deposit color but

do not lift color

A capacity to lift natural color from the hair is a feature of

permanent haircolor

The tint molecules of permanent haircolors cannot be shampooed out because they are trapped in

the cortex

The uncolored dye precursors in permanent haircolors are

aniline derivatives

The oxidizer used most often in haircoloring is

hydrogen peroxide

The measure of the potential oxidation of varying strengths of hydrogen peroxide is

volume

A haircolor product used to achieve pale and delicate colors on prelightened hair is

toner

During a client consultation for haircolor, mentioning a TV celebrity's haircolor as a possibility would likely

be helpful

Possible allergy to an aniline tine or toner is determined by a

patch test

The hair processes color more quickly

at the scalp

Unwanted orange tones can be corrected by using a haircolor with

a blue base

Specialized preparations called fillers are used to equalize porosity and

deposit a base color

Once you have mixed and used a tint, any remaining tint should

be discarded

Blue

the darkest primary color

Blue-green

a tertiary color

During hair coloring, coarse hair may

take longer to process

Low porosity

one reason why resistant hair requires more time to process

Contributing pigment is exposed when you

lighten natural hair color

The predominant tonality of an existing color is called its

base color

Bleaching or decolorizing is also called

lightening

One of the roles of the alkalizing agent in permanent haircolors and lighteners is

to raise the cuticle

A developer supplies oxygen to develop color molecules and create

a change in hair color

In a one-step color service with high-lift colors, the hydrogen peroxide is

40 volume

An example of a natural haircolor is

henna

Dispersing, dissolving, and decolorizing melanin, the natural hair pigment, is the function of

lighteners

The goal when decolorizing is to create the correct degree of

contributing pigment

The baby-blonde look is achieved by lightening the hair to pale yellow and using a toner to neutralize

the undertone

Many salons use release statements when providing chemical services to explain if hair is

in proper condition to receive color

Semipermanent haircolors will take on the hair to various degrees, depending on

the hair's porosity

After lightening the hair in a double-process application, you apply

the depositing color

Activators may be added to cream lighteners to

increase their lifting power

The fast-acting lighteners used off the scalp come in

powder form

Lightener retouch services should not be done with

powder lightener

Partings of 1/8" are taken when

applying lightner

Hair can go through up to __________ of decolorizing

10 degrees

In the technique called low-lighting, strands of hair are colored

darker than the natural color

Sometimes it is necessary to treat gray or very resistant hair to allow for better color penetration, by using a product called a

pre-softener

The foil technique is which selected strands are picked up with a zigzag motion of the comb is called

weaving

Use of a filler may be key to a successful

tint back to natural

For satisfactory results when you formulate a color filler, remember to

replace the hair's missing primary color

For a client with excessive brassiness in her tinted hair, the best solution is to

neutralize with the complementary color

Soap caps, often used in tint backs, are a combination of shampoo and

tint
