Have you ever played attention to the fact it is really difficult to find two people with absolutely identic hair color, as well as to achieve the same color on two different chevelures using the same hair-dye? The secret is that hair color is individual and the result of hair coloring is always unequal. So hairs color itself as well as hair coloring effect depends on the original hair pigmentation.Hair color is based on the pigmentation of hair follicles in consequence of two types of melanin, eumelanin and phaeomelanin. As a rule, it depends on the total melanin amount, if the color of the hair is darker or lighter. Let’s look upon two types of pigment: eumelanin and phaeomelanin. Phaeomelanin makes hair red. Eumelanin has two types black or brown, determines the darkness of the hair color. A low concentration of brown eumelanin makes blonde hair, subtypes a higher concentration of this pigment makes the hair brown. All humans have some phaeomelanin in their hair but it is not always noticeable. The amount of this pinment determines the hair contrast. This is the main explanation for different results of hair coloring.
Hair color can be changed by a chemical process. As you have already known the hair coloring result will depend on the eumelanin and phaeomelanin amount. For example, it is usually difficult to make dark brown hair blond or even fair. Besides difficulties with the hair coloring you’ll face the problem that hair become darker after some time, it aligned with he pigment’s feature to restore. Now you can reason yourself about two main points at issue about hair coloring: if it really harms your hair and it is really difficult for the brunette to become blonde. You know it all depends on the pigment concentration.
If you prefer hair coloring you should choose between permanent hair color and semi-permanent color:
Permanent hair coloring can make hair lighter or darker as well you can change your hair color radically with it. You may also choose a perfect color congenial to your own hair color. Statistically women prefer permanent color. If you are a one of them, keep in mind that you need to color your hair roots every four to eight weeks.
You may change the color with the other type - semi-permanent color. It usually washes out over a period of time - typically four to six weeks. The final color is affected by the original color so it is not appropriate for gray and white hair.
