hair coloring terminology pre-salon Flashcards
need to know
applying a small amount of haircolor or bleach on the skin to check for sensitivity and /or an allergic reaction to the chemical
Predisposition test or patch test
determines if the haircolor is absorbing and processing evenly
processing strand test /periodic strand test
what system provides an understanding of color relationships?
the law of color
the three basic colors that all other colors are made from
red blue yellow
created by mixing two primary colors
secondary colors
created by mixing a primary and secondary color
tertiary colors
created by mixing a primary color and secondary color that is across the color wheel
complementary colors
the balance of color
tone or hue
the warm or cool tone seen within the predominant hair color
undertone also known as contributing pigment
the strength of a colors pigment
intensity
the middle layer of hair made up of elongated cells containing melanin and keratin is called
cortex
the innermost layer of hair composed of round cells, hair missing this layer is fine or fragile
medulla
the coloring matter that provides us with the pigment of our hair and skin
melanin
produces brown to black pigments of the hair
eumelanin
produces yellow and red pigments of the hair
pheomelanin
the system used to determine the lightness or darkness of a color
level system
the degree of lightness or darkness of a color
level
the medical term for gray hair, the result of a gradual decline in melanin
canities
softening the hair cuticle for better penetration often used prior to haircoloring gray and or/ resistant hair
presoftneing
the science that deals with the composition structures and properties of matter ans how matter changes under different chemical conditions
chemistry
a substance used in, or produced by, the process of chemestry
chemical
the study of living or previously living organisms that contain carbon
organic chemestry
the study of not living or never living organisms that do not contain carbon
inorganic chemestry
substance that has mass occupies space, occours in the for m of a liquid a solid or a gas
matter
the simpelest form of matter
element `
the smallest chemical part of an element
atom
parts of the atom that have a positive charge
proton
particles in an atom that have a neutral charge
neutron
particles in an atom that have a negative charge
electron
an atom or group of atoms carring an elecrtic charge
ion/ions
two or more atoms chemically joined and retain their chemical and physical properties to form matter
molecule
a chemical compound of two or more atoms from different elements
compound molecule
stable mixtures of two or more substances which may be solid, liquid,gas, or combination of these
solutions
a substance that is capable of dissolving another substance
solvent
a mixture in which small particles of a substance are dispersed throughout a gas or liquid. if left undisturbed the particles are likely to settle and separate
suspension
the suspension of one liwuid into a second liquid with which the first will not mix
emulsion
used to neutralize acids or raise ph may be used in place of ammonia because it produces less odor
alkanolamines
small compounds also known as uncolored dye precursors found in permanent haircolor
aniline derivatives
temporoay colors that take no chemical reaction or mixing to produce
non oxidative haircolor
creates a chemical change in the hair therefor providing longer lasting tesults permanant and demi-permanant haircolor
oxidative haircolor
oxidizing agent added to haircolor or lightner that assists in the devlopment process
developer
