THERE ARE TWO DIFFERENT TYPES OF MELANIN

•Eu-melanin →large molecule, brown/violet →easy to lift

•Phaeo-melanin →small molecule, red/orange →hard to lift

The quantity and combinations of the melanin pigments define the natural hair color. Grey hair
appears when melanocytes do not produce melanin any more. Because of this, the hair
becomes white. The cells in the cuticle also change and this makes the hair coarse.

Hair is hydroscopic, which means to attracts moisture . The amount of moisture it attracts
depends on the humidity, temperature and the condition of the hair. When moisture is
attracted the hair swells up.

COLOR THEORY: Composition of Light

 White light is composed of a large number of waves of different frequencies.

 Each component frequency produces a characteristic color sensation.

 The different components of light can be made visible by dispersion of light.

 An example of light dispersion is a rainbow.

 When a beam of light passes through a refracting material such as a prism, each
component is refracted differently.

 White light is separated into different component colors.

COLOR IS A REFELECTION OF DIFFERENT FREQUENCIES

Hair with a red color, reflects the red light frequencies. The other colors, which are available on
white light, are absorbed. In case all colors are absorbed, light stops to exist and you see the

opposite of light, namely black.

The natural hair color is composed out of 3 primary colors: Red, Yellow and Blue. Combinations
of the 3 primary colors give 3 secondary colors:

red + yellow = orange red + blue = violet blue + yellow = green

The primary and secondary colors opposite to each other in the color wheel are the
complementary colors. These are the colors which are used to neutralize colors.
