Basics of Hair Colors
If you know the color wheel color becomes easy...
It may sound a bit odd but your hair is a mixture of 3 colors; red
yellow, and blue. These are the primary colors. Secondary colors are
orange, green, and violet. If you look at the "wheel" a color opposite
(directly across) will "negate" that color. This means if your hair is
a orange color - blue will make it a brown/black color. If you hair has
a yellow tone, violet will cancel it out.
One of the most important elements of haircoloring is determining the hairs' "underlying pigmet" (the hairs' natural color.) When you chose a color in a swatch book, your hair may not come out that color because of the underlying pigment in your hair.
Underlying color + Artifcial color = Final result

Types of Haircolor
- color lasts from one shampoo to the next and is deposited on the
outside of the hair shaft.
Semi-Temporary - color lasts up to 4-6
shampoos. Usually contain no ammonia and does not have a developer.
Demi Permanent - color usually contains little or no ammonia and utilizes a low peroxide developer (under 10 vol.) the color lasts about 6 weeks and fades gradually back to the natural shade.
Semi-Permanent - color usually contains some ammonia and uses a deloper of 10 to 20 vol.
Permanent - color formulas change the natural hair color. They require maintenance to new hair growth after 4 to 6 weeks. (For the purposes of this guide we will be discussing Permanent colors and methods of processing only.)
How it Works
Before any permanent color can be deposited into the hair shaft, the cuticle, or outer layer, must be opened. The insoluble formula then reacts with the cortex, or middle layer, to deposit or remove the color. The color is available in a variety of forms; creams, gels or tubes, or shampoos. These will not permanently change the hair color until they are part of an oxidation chemical reaction.
The Oxidizing Agent or Developer is hydrogen peroxide in one of various forms and strengths. lt is the catalyst or cause of the chemical reaction which allows the formula to permanently alter the hair's color. The strength of the developer - is determined by the desired results and the manufacturer's directions.
- 10 Volume - Color deposit with only slight lightening.
- 20 Volume - Maximum color deposit as for gray or white hair with lightening
- 30 Volume - Strong lightening action with less color deposit.
- Bleaching Boosters - can be added to increase lifting action.
