It's caused by the reduction/loss of melanin, which is the pigment that gives hair its colour. The cells which create melanin slowly die until they are all gone and the hair goes completely white.

Ever notice if u put food coloring in a snow man when u were little, the first day, it was just fine and dandy. The second day, it sort of started 2 run and u saw a few faults here and there. The third day, it was all over the place and wasn't pretty any more. The fourth day the color was still messy, and now it was drained out. The fidth day, there is no more color.

As the older peeps get older, so does their hair, and their hair color. Just like as u get older, you get sick, think of it as your hair getting sick, and getting frail and grey and stuff. As you get older, you start to loose the pigment in your hair, which gives it color.

A change in hair color typically occurs naturally as people age, usually turning their hair from its natural color to grey, then to white. More than 40 percent of Americans have some grey hair by their fortieth birthday, but grey hairs can appear as early as the teens and twenties for some, or even in childhood. The determination of when someone begins greying, whether it comes with aging or prematurely, seems to be almost entirely based on genetics. Sometimes people are born with grey hair because it is passed down genetically. Many people use hair dye to disguise the amount of grey in their hair.

The change in hair color is caused by the gradual decrease of pigmentation that occurs when melanin ceases to be produced in the hair root, and new hairs grow in without pigment. Two genes appear to be responsible for the process of greying, Bcl2 and Mitf. The stem cells at the base of hair follicles are responsible for producing melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes hair to begin going grey.[1]

There are no special diets, nutritional supplements, vitamins, nor proteins that have been proven to slow, stop, or in any way affect the greying process, although many have been marketed over the years. This may change in the near future, however. French scientists treating leukemia patients with a new cancer drug noted an unexpected side effect: some of the patients' hair color was restored to their pre-grey color. [1]

A 1996 British Medical Journal study conducted by J.G. Mosley, MD found that tobacco smoking may cause premature greying. Smokers were found to be four times more likely to begin greying prematurely, compared to nonsmokers in the study.[2]

The color of the hair of mummies or buried people can change over large time periods. Hair contains a mixture of black-brown-yellow eumelanin and red phaeomelanin. Phaeomelanin is much more stable than eumelanin, so that the phaeomelanin in the hair is better preserved over time than the eumelanin. The color of hair changes faster under extreme conditions. It changes more slowly under dry oxidising conditions (such as in burials in sand or in ice) than under wet reducing conditions (such as burials in wood or plaster coffins)

As you get older you loose the pigment in your hair which gives you colour. It's also harder to dye your hair when you get old as you need this pigment to colour your hair using dye. Most animals hair/fur will change aswell as they also have pigment just like us.

People get white hair when they're older because the stuff in your head that produce the color of your hair become slower and slower as you get older and your hair just starts turning white because the stuff have stopped working.
