Anatomy
Produces brown to black pigments in the hair
Eumelanin
Created by mixing two primary colors in equal proportions
Secondary Color
A deposit-only hair color that penetrates into the cuticle layer
semi-permanent haircolor
Technique that allows for better hair color penetration by softening the cuticle of primarily resistant or gray hair
Presoftening
May be used in place of ammonia because they create less odor and neutralize acids or raise the pH
Alkanolamines
The coloring material that provides a person with their natural hair and skin color
Melanin
Temporary haircolor that requires no mixing or chemical reaction
non-oxidative haircolor
Will determine if the hair color is absorbing and processing evenly
Processing Strand Test
The technique of removing color from the hair
Decolorization
On the pH Scale, acids range from

Glae
Applying a small amount of product to the skin to check for sensitivity/allergic reaction
Predisposition Test

Produces yellow to red pigments in the hair
Tone
Utilizing a single application of hair color to either lighten the natural hair color or to deposit color
