Hair Colouring is both the Science and the Art of changing the colour of hair. Every hair colour service will affect and be affected by the structure of hair. Some hair colour products cause a dramatic change in the hair’s structure, while others affect it very little. A very important point to note is that when a product significantly changes the hair structure, it usually creates a weaker strand of hair. It is for this very reason that we do not recommend bleaching for persons with relaxed hair.
One must remember that in order to get true colour, you must remove colour. The art here is to therefore, remove your natural hair colour without the use of bleach!
The science is that your natural hair colour is stored in the form of Sulphur and Gases. Basically, knowing your natural hair colour level helps you to calculate your destination. This is how it works, when artificial colour is applied to your natural hair colour, it causes some sulphur and gases to escape, thus causing the artificial colour molecules to resonate on the cortex layer.
How Hair Pigment Is Derived
The cortex of the hair contains the basic coloring matters, minute grains of melanin or pigment.
Melanin has two possible manifestations. Eumelanin, which has an oval or elliptical shape is found in black and brunette hair and is a dark pigment. The higher the concentration of eumelanin, the darker the hair.
Phaeomelanin is a light pigment that is found in blonde and red hair. The higher the concentration of phaeomelanin, the lighter the hair. Unlike eumelanin, phaeomelanin is smaller, partly oval and has a rod shape.
A mixture of the two different pigments can be found at the same time in many people. Melanin an its existence is genetically predetermined. White hair contains no melanin at all and gray hair contains only a few melanin granules. Gray hair melanin is usually spread out throughout the entire head of hair.
Many people's hair contains a mixture of the two: the more eumelanin there is in the mixture, the darker is the hair. The mixture (and the shade) varies not only from one person to another, but also across one person's head.
Hair color experts study the theory of color pigment. It is only through understanding hair pigments and correct color formulations that the correct color can be chosen and applied to hair color clients.
Although some scientists believe that the derivation of pigment is probably derived from colo-forming substances in the blood. The color of the hair, light or dark, depends upon the color and amount of the grains of pigment it contains.
Hair color is created by the movement of light rays either as they are absorbed or reflected by artificial pigment added to the hair in the tinting process, or by natural hair pigment
Process takes about 30 – 45 mins.
