Hair change with aging

Older people tend to develop gray hair (actually colorless) because the pigmentation in the hair gets lost and the hair becomes colorless. The age at which this occurs varies from person to person, but in general nearly everyone 75 years or older has gray hair, and in general men tend to become gray at younger ages than women.

The older a person is, the more likely he or she is to have gray hair, and above 85 almost nobody has his or her original hair color. Gray hair is considered to be a characteristic of normal aging.

People starting out with very pale blond hair usually develop white hair instead of grey hair when aging.

Some degree of scalp hair loss or thinning generally accompanies aging in both males and females, and it's estimated that half of men are affected by male pattern baldness by the time they're 50.{{ref|halfofmen}} The tendency toward baldness is a trait shared by a number of other primate species, and is thought to have evolutionary roots.
