Hair Coloring Flashcards
Predisposition test
Also, known as a patch test, is applying a small amount of product on the skin to check for sensitivity, and or an allergic reaction to a product or chemical
Processing strand test
Also known as a periodic strand test, determines if the hair color is absorbing and processing evenly
Color wheel
Hey, support tool for the law of color to visually show how all colors are created
Law of color
Hey system that provides an understanding of color relationships
Primary colors
The three basic colors, red yellow blue, from which all other colors are produced
Secondary colors
Created by mixing two primary colors in equal proportions
Tertiary colors
Created by missing a primary color with the neighboring secondary color
Complementary colors
Created by mixing it primary, and a secondary colors that are located opposite of each other on the color wheel
Tone
Also known as hue, is the balance of color
Undertone
Also known as contributing pigment, is the warm or cool tone seen within the predominant haircolor
Intensity
The strength of the colors appearance
Cortex
The middle layer of hair, made up of Elongated cells containing melanin in keratin
Medulla
The innermost layer of hair composed around, sells hair. Missing the medulla is fine or fragile.
Melanin
The coloring matter that provides us with a natural color of my hair and skin, also known as pigment
Eumelanin
Produces brown to black pigments in the hair
Pheomelanin
Produces yellow to red pigments in the hair
Level system
Hey, system used to determine lightness or darkness of a color
Level
The degree of lightness or darkness of a color
Canities
The medical term for gray hair, the result of a gradual decline in melanin
Pre-softening
The technique that allows for better hair color, penetration by softening the cuticle ,often use prior to hair, coloring resistant, and or gray hair
Chemistry
The science, that deals with the composition and structure and properties of matter and how matter changes under different chemical conditions
Chemical
A substance used in or produced by the process of chemistry
Organic chemistry
 The study of living or previously living organisms contain carbon
In organic chemistry
The study of not living or never living organisms that do not contain carbon
Matter
Substance that has mass and occupy space occurs in the form of a solid liquid or gas
Element
The simplest form of matter, it cannot be broken down into a simpler substance
Atom
The smallest chemical part of an element
Proton
Particles in an atom that have a positive charge
Neutron
Particles in an atom to have a neutral charge (having no positive or negative charge)
Electron
Particles in an atom that I have a negative charge
Ion
And atom or group of atoms, carrying an electric charge
Molecule
Two or more atoms, chemically joined, and retain their chemical and physical properties to form matter
Compound molecules
Also known as compounds, or chemical combination of two or more atoms from different elements
Oxidation
Chemical reaction that occurs when oxygen is released from a substance this reaction assist in the development of color on the hair
Combustion
The rapid oxidation of a substance accompanied by the production of heat and light
Pure substances
Have definite chemical and physical properties
Solutions
Stable mixtures of two or more substances, which may be solid, liquid, gases, or a combination of these
Solvent
A substance that is capable of dissolving another substance
Suspension
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 in separate.
Emulsion
The suspension of one liquid in a second liquid with which the first will not mix
Ammonia
A gas with an strong odor made up of nitrogen and hydrogen
Alkanolamines
Used to neutralize acid or raise the pH may be used in place of ammonia, because they create less odor
Aniline derivatives
Small compounds also known as uncolored dye precursors, found in permanent hair color
Acid
Ranges from 0 to 6.9 on the pH scale.
Alkaline
Ranges from 7.1 to 14 on the pH scale.
Nonoxidative, hair color
Temporary color, no chemical, mixing or reaction takes place to produce these colors on the hair
Oxidative, hair color
Creates a chemical change in the hair there for providing longer lasting hair coloring result types of these hair colors are permanent hair color in Demi, permanent hair color
Developer
Also known as catalyst and hydrogen peroxide, oxidizing agent added to hair color, or Laettner that assist in the development process, it is manufactured in various strength, also known as volume or percentages
Decolorization
The technique of removing natural hair color or artificial hair color from the hair
Lightner
Also, known as bleach or decolorizer, will live permanently by diffusing, dissolving, or decolorizing, with natural or artificial pigment in the cortex
