Question | Answer |
---|---|
The science and art of changing your guests current hair color by adding or removing color. | Haircoloring |
Also known as patch test, determines if an individual is allergic to haircolor products containing aniline derivative dye molecules | Predisposition Test |
Will determine if the haircolor is absorbing and processing evenly. | Processing Strand Test |
The soft, elastic, thick, inner layer made up of elongated cells that bond together tightly. | Cortex |
The deepest layer, consisting of round cells. | Medulla |
The tough outer protective covering | Cuticle |
The coloring matter that provides natural color to our hair, skin, and eyes. | Melanin |
Produces brown to black pigments in the hair | Eumelanin |
Produces yellow to red pigments in the hair | Pheomelanin |
The medical term for gray hair | Canities |
Increases the porosity of the hair, opening the cuticle, allowing for more pigment to be absorbed. | Presoftening |
The science that deals with the composition, structures, and properties of matter and how matter changes under different chemical conditions | Chemistry |
A substance used in, or produced by, the processes of chemistry | Chemical |
Studies matter that contains carbon and is living or at one time was alive | Organic Chemistry |
Studies substances that do not contain carbon and are not living or alive | Inorganic Chemistry |
A substance that has mass and occupies space | Matter |
The simplest for of matter that cannot be broken down into a simpler substance | Element |
The smallest chemical part of an element | Atom |
Positively charged particles found in the nucleus | Protons |
Neutral particles found in the nucleus | Neutrons |
Negatively charged particles that revolve around the nucleus on orbiting paths and are involved in chemical bonding with other atoms | Electrons |
Atoms containing an excess amount of electrons or not enough electrons in their orbiting paths | Ions |
Created when one or more atoms combine and retain their chemical and physical properties to for matter | Molecule |
Also known as compounds, are a chemical substance consisting of atoms or ions of two or more elements in definite proportions that cannot be separated by physical means | Compound Molecules |
The chemical reaction that occurs when oxygen is released from a substance | Oxidation |
The rapid oxidation of any substance, accompanied by the production of heat and light | Combustion |
Matter that is made up of the same type of particle throughout and have a definite chemical and physical property | Pure Substances |
A stable mixture of two or more substances, which may be solids, liquids, gases, or a 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 | Suspension |
The suspension of one liquid in a second liquid with which the first will not mix | Emulsion |
An ingredient that is used to keep two incompatible substances together | Emulsifier |
An organic compound of colorless gas with a strong, pungent odor, composed of nitrogen and hydrogen | Ammonia |
A support tool for the law of color to visually show how all colors are created | Color wheel |
A system that provides an understanding of color relationship | Law of color |
The basic colors.....rred,yellow,blue....from which all other colors are produced | Primary colors |
Created by mixing two primary colors in equal proportions | Secondary |
Created by mixing a primary color with a neighboring secondary color | Tertiary color |
Created by mixing a primary and a secondary color that are located opposite each other on the color wheel | Complementary colors |
Also known as hue, is the balance of color | Tone |
Also known as contributing pigment, is the warm or cool tone seen within the predominant haircolor | Undertone |
The strength of the color's appearance | Intensity |
Used to neutralize acids or raise the pH. May be used in place of ammonia because they create less odor | Alkanolamines |
Small compounds, also known as uncolored dye precursors, found in permanent haircolor | Aniline Derivatives |
Ranges from 0 to 6.9 on the pH scale | Acid |
Ranges from 7.1 to 14 on the pH scale | Alkaline |
Temporary colors; no chemical mixing or reaction takes place to produce these colors on the hair | Non-Oxidative Haircolor |
Creates a chemical change in the hair therefore providing longer lasting haircolor results. Ex. Permanent and demiperminant haircolor | Oxidative Haircolor |
Also known as Catalyst or Hydrogen Peroxide, oxidizing agent added go haircolor or lightener that assists in the development process; it is manufactured in various strengths, known as volumes or percentages | Developer |
The technique of removing natural hair color or artificial haircolor from the hair | Decolorization |
Also known as bleach or decolorizers, will lift permanently by diffusing, dissolving or decolorizing the natural or artificial pigment in the cortex | Lightener |
Come in an oil, cream and some powder forms and are able to be used on the scalp | On the scalp lightener |
Also known as Quick Lighteners, come in a powder for and are not able to be used on the scalp | Off the scalp lightener |
Semi-permanent or demi-permanent haircolor product used on pre-lightened hair to neutralize unwanted pigment | Toner |
Used to equalize porosity and replace missing pigment in one application | Filler |
A product used to make another product more intense, vibrant, stronger, or purer | Concentrate |
A concentrate haircolor used to increase the ability of a haircolor to neutralize unwanted warmth of a color | Drabber |
