When mixed together (yellow, red, blue) create all other colors. Are known as pure colors.
Made by mixing primary colors with neighboring seconday color in equal proportions. (yellow-orange, yellow-green, blue-green, blue-viloet, red-violet, red-orange)
Colors found opposite one another on the color wheel. The neutralize or cancel out one another when they are mixed together.
Pigment-producing cells in the hair bulb that produce small egg-shaped structures (Melanosomes).
Pigmented granules that becomes incorporated into the keratin protein of the cortex as the hair grows.
Eumelanin (Black Pigment)
A dense concentration of this melanin will produce very dark hair. A small population of this melanin will produce light blonde hair.
Are not mixed with a developer and are applied directly to the hair, depositing colors that shampoo out. (Temporary / Semi-permant color)
Non-reactive, direct dyes, contain large color molecules that coat only the surface of the cuticle. Lasts from shampoo to shampoo
Accepted by the Foof & Drug Administration (FDA) for use in foods, drugs and cosmetics
A chemical compound or mixture of compounds that consists of many molecules in a long chain-like structure. Found in many products, including nonoxidative and oxidative colors. Adds shine or conditioning qualities to the hair, used as thickening agent.
Use direct dye process, need no mixing and the color you see in the bottle is the color that is deposited on the hair. These colors are alkaline and generally last through serveral shampoos. Leaves no line of demarcation
Mixed with developer to create chemical change that has long lasting effect. Can deposit or lift (lighten natural melanin) and deposit color in single process
Use low volume peroxideto develope the color molecules and aid in the color processing. generally lasts 4-6 weeks
mixed with hydrogen peroxide and capable pf both lifting natural pigment and depositing artificial pigment in one process
Light pastel colors used to tone prelighted hair. Contain aniline derivates, a predisposition test required
Provide an even base color by filling in porous, damaged or abused areas with materials such as protein or polymers. Equalize the porousity and deposits a base color in one application.
used on damaged hair and when there is aquestion as to whether or not the color will hold, such as with porous hair.
Concentrates, Intensifiers, Pigments and Drabbers
Products designed to increase the vibrancy of a color formula or to neutralize tones
Lighteners or Bleaches
Used to removed or diffuse melanin, create the final color result or create a new pifment on which to build the final hair coloring.
Lightener that can be applied to scalp, has a pH around 9, comes in two forms, Oil & Cream
comes in powder form, when mixed with peroxide, becomes a strong lightening product., can irritate the scalp, causing blisters & burns
Oxidizing agents used with Demi-permanent & permanent colors, lighteners and toners. My be referred to as Catalyst or Conductor.
The most commonly used developer in hair coloring products. pH is between 2.5 and 4.5. Needs to be mixed with ammonia or other alkaline compounds to become active.
used to measure the strength of Hydrogen Peroxide and allows you todilute higher strengths to lower. Also beneficial to determine whether hydrogen peroxide that has been stored for a long time is potent
Base to Ends
Used when you want to add tone to or darken the existing color. Also known as a virgin darker technique
Weaving & Slicing
Techniques are generally used to add depth and demension (Hightlights or lowlights) to the existing hair color
Selected strands are pulled through perforated holes in a rubber coloring cap with a crochet hook
