Older people tend to develop grey hair because the pigment in the hair is lost and the hair becomes colourless. Grey hair is considered to be a characteristic of normal aging. The age at which this occurs varies from person to person, but in general nearly everyone 75 years or older has grey hair, and in general men tend to become grey at younger ages than women.
It should be noted however, that grey hair in itself is not actually grey - the grey head of hair is a result of the contrast between the dark and white/colorless hair forming an overall 'grey' appearance to the observer. As such, people starting out with very pale blond hair usually develop white hair instead of grey hair when aging. Red hair usually doesn't turn grey with age; rather it becomes a sandy color and afterward turns white. In fact, the gray or white appearance of individual hair fibers is a result of light scattering from air bubbles in the central medula of the hair fiber. Some degree of scalp hair loss or thinning generally accompanies aging in both males and females, and it's estimated that half of all men are affected by male pattern baldness by the time they are 50[2]. The tendency toward baldness is a trait shared by a number of other primate species, and is thought to have evolutionary roots.

You start to grey all over your body when you start to go grey, yes premature greying is a nuisance...me too, worse if you have dark hair, it doesn't show on fair hair.

There is a verse in Proverbs that says, A crown of gray hair is a crown of wisdom.
