At some point in their life, almost every adult has asked themselves one simple question. Just why does our hair turn grey? It doesn't help that the way it appears on different people is a mystery. It isn't at all unusual to see a thirty year old man who appears completely healthy to have a full head of grey hair. Just the same there are many fourty five year olds with practically no grey hair at all. Luckily we can look to science for grey hair causes

While you cannot deny aging forever keeping your hair from turning grey can make a big difference. If you are interested in methods of keeping your hair grey through dye, or other methods then you should do some research online to find a method that works for you.

Our hair basically has two different parts. There is the shaft of each hair that you can see coming out of the skin, and the other part is the root which is buried underneath the skin. Attached to every single root is a follicle. These follicles control the way every individual hair appears. Among these things it controls the color of a person's hair.

A follicle is made of of cells that produce melanin. Melanin is the pigment that gives your hair its color. Melanin is also the substance known for producing our skin color as well. When it comes to hair color there are two different types of melanin: phaeomelanin and eumelanin. Phaeomelanin produces several different types of light hair color and the other, eumelanin, is known for producing all of the different dark hair colors. You hair will contain blends of both types a melanin, and that is why we as humans can have such a broad range of different hair colors.

As humans get older the cells inside the follicle begin to die off. Thus, the amount of melanin being produced will be reduced greatly. As you can probably guess, this is when hair begins to turn grey. In most people this will be a very slow process. After all we each have over a hundred thousand individual hairs, each with its own separate set of melanin producing cells in the follicle. For most people it can take as much as ten years for all of their hair to turn grey. The age at which this happens can be based on several different things. The most likely have to do with heredity and diet.
