Every one of us looks at our hair every day but do we really see it? Do we see all the components that make up just one strand of hair? For most of us no we do not take our hair for granted. Its there where its suppose to be and that's good enough. For the professional hair stylist though that is not near enough. They must be aware of all of the components of the hair and how they are going to react to the numerous services perform on them. This is especially true when it comes to hair coloring services.
The various hair textures are the determining factor when it comes to quality and density of the color. The various textures all respond differently when it comes to color. This is the very reason why a stylist much have a solid knowledge in the basic structure of the hair.
There are many contributors to hair color away from texture. There is the individuals overall health, the climate they live in, their ancestry, as well as age.
The hair is dependent, large, on genetic factors and the environmental surroundings for its structure and form. Heredity, age, physical condition and climate all contribute to color, strength and growth of hair.
When one starts a thorough study of the hair, it's hard to phantom the complexity of each and every single hair. It starts its growth from the follicle emerging from a papilla that is made up of living cells. Here mitosis or cell multiplication occurs to start the formation of the hair. As these multiple cells receive oxygen and continue to grow, they remain in a soft state while the outer cells become flattened against the follicle wall where they are now known as the hair cuticle. In this state not only have they become flat they are now hard and scaly and have taken on the job of encompassing the hair by overlapping one another. The cuticle has several layers, which in turn protect the inner cortex. This cortex is the most important layer and makes75 to 90% of the hair. This is where the pliability, strength, elasticity, texture, growth direction and quality of the hair are formed.
In some hairs, there is a central core. This is the medulla which is present in some hairs but not in others. Alternately, some hair may even have two. Keratin is the hair build up and protein. Sulfur is one item contained within the protein and is what gives hair its strength. Coloring affects the balance of these proteins, and over processing, weakens the hair to the point where it becomes brittle.
The hair goes through three growth cycles being antigenic which is the growth phase. Antigenic second phase where it starts to slow down and finally the telegenic stage, which is the resting stage.
The natural hair color of the hair comes from melanin. The melanin begins as a clear substance that goes through a course of various changes which finally it ends up as black pigment where it continues to go through changes and finally based on the size of the granules it depicts the darker or lighter hair. Gray hair is simply a hair mixture of white hair with natural color. In the end, it comes down to all the different natural hair colors that we see are corresponded of various mixtures of black, brown, red and yellow pigments.
