Created by mixing two primary colors in equal proportions:

Will determine if the haircolor is absorbing and processing evenly:

processing strand test

100

A concentrated haircolor that is added to deepen, brighten, or create a more vivid look:

intensifier

100

Coloring some hair strands darker than their natural color:

lowlighting

The study of living or previously living organisms containing carbon:

organic chemistry

300

The middle layer of the hair, made up of elongated cells containing melanin and keratin:

cortex

300

Describes the degree of lightness or darkness of a color:

level

300

The technique of removing color from the hair:

decolorization
