hair color Flashcards
the cuticle layer protects the cortex layer and contributes this percentage of the hairs overall strength
20 percent
the cortex of the hair gives strength and elasticity and contributes how much to the hairs overall strength
80 percent
hair texture is determined by the what of the individual hair strand
diameter
this is the number of hairs per square inch on the head
density
permed, colored, relaxed, and straightened hair will have what degree of porosity
high
this is the hairs ability to absorb moisture
porosity
the melanin that gives black/brown hair its color
eumelanin
the melanin found in red hair
pheomelanin
this is the method used to analyze the lightness or darkness of a hair color, whether natural or artificial
level system
what is the predominant tonality of an existing color referred to
base color
what system is used to understand the relationships among colors
law of color
what are considered the pure/fundamental colors and what are they called
red, blue, yellow
colors with a predominance of blue are considered what tones
cool
colors with a predominance of red are considered what tones
warm
these colors are achieved by mixing two primary colors together
secondary
equal parts of blue and yellow mixed creates what color
green
equal parts of red and yellow mixed created what color
orange
equal parts of red and blue mixed creates what colors
purple/violet
what is an intermediate color achieved by mixing a secondary color and its neighbor primary color
tertiary
primary and secondary colors that are directly opposite on the color wheel are considered what
complementary
which of the following describes the warmth/coolness of a color
tone
the strength of a color is referred to as
intensity
what product is used to raise the cuticle of the hair so that the color may penetrate into the cortex
alkalizing agent
what four categories of hair color are there
temporary, semi, demi, permanent
what type of color product uses the largest pigment molecules
temporary
colored mousses and gels are included in what color category
temporary
the color that partially penetrates the hair shaft and stains the cuticle layer, slowly fades with shampooing
semi permanent
color that is ideal for covering unpigmented hair, refreshing faded permanent color, and depositing tonal changes without lifting
demi permanent
color that remains in the hair shaft and cannot be easily shampooed out
permanent color
the tint formula in permanent color contains uncolored dye ? or aniline derivatives which are small compounds that can diffuse in the hair shaft
precursors
what product is a combination of equal parts of a permanent color mixture and shampoo that is used in the last 5 minutes of a color service
soap cap
what is an example of a natural/vegetable color
henna
metallic colors are also called what
gradual
this is an oxidizing agent that when mixed with an oxidation color, supplies the necessary gas to develop color molecules and create a change in hair color
developer
what is the most commonly used developer in color
hydrogen peroxide
the measure of the potential oxidation of varying strengths of peroxide is
volume
chemical compounds that lighten hair by dispersing, dissolving and decolorizing the natural hair
lightener
when arranging for a color consultation what color walls are recommended
white/neutral
this form is designed to protect the school/salon owner from responsibility for accidents or damage
release statement
permanent color is applied by either the bowl and brush method or this method
applicator
the US Federal Food, Drug, and Cosmetic Act prescribes that a patch test, also known as this, be given 24-48 hours prior to an application of aniline color
predisposition
the preliminary strand test will tell you how the hair will react to the color formula and indicated this
processing time
this is a process that lightens and colors hair in a single application
single process
a non ammonia color that adds shine and tone to the hair is called what
glaze
what is the visible line that separates colored hair from new growth
line of demarcation
what are the three types of hair lightener
cream, oil, powder
what can be added to hydrogen peroxide to increase lifting power
activator
which type of lightener is not used directly on the scalp
quick lightener
porous hair of the same color level will lighten faster than nonporous hair due to the lightening agent entering what more rapidly
cortex
this lightener is generally used to a lightener retouch because its consistency helps prevent overlapping of previously lightened hair
cream
the technique of coloring strands of hair darker than the natural color is called reverse highlighting or this
Low lighting
the two methods of parting hair for a foil technique are
weaving and slicing
the free form technique of hair painting is called
baliage
a product prepared by combining permanent color, hydrogen peroxide, and shampoo is
highlighting shampoo
the process of treating gray or very resistant hair to allow for better penetration of color is known as
pre soften
what is the first and most important guideline when color services do not turn out as planned or expected
do NOT panic
these are specialized preparations designed to help equalize porosity and deposit base color in one application
fillers
one of the many safety pre cautions in coloring is to never apply color if these are present
abrasions
when applying color products you should always follow what
manufacturer’s directions
a patch test is generally conducted in what two areas
behind ear, inside/fold of elbow
