Grey hair usually denotes a lack of the pigment melanin in the hair. As we age, the body often begins to produce less and less melanin.

Some grey hair is caused by thyroid problems.

Why does people hair turn gray when they get old?

Hair turns gray as people age due to a decrease in melanin production in the hair follicles. Melanin is the pigment responsible for giving hair its color. As we age, our hair follicles produce less melanin, causing hair to appear gray or white.

Why would you get gray hair?

the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color - like gray, silver, or white - as it grows. As people continue to get older, fewer pigment cells will be around to produce melanin. Eventually, the hair will look completely gray. People can get gray hair at any age. Some people go gray at a young age - as early as when they are in high school or college - whereas others may be in their 30s or 40s before they see that first gray hair. How early we get gray hair is determined by our genes. This means that most of us will start having gray hairs around the same age that our parents or grandparents first did. Gray hair is more noticeable in people with darker hair because it stands out, but people with naturally lighter hair are just as likely to go gray. From the time a person notices a few gray hairs, it may take more than 10 years for all of that person's hair to turn gray. Some people think that a big shock or trauma can turn a person's hair white or gray overnight, but scientists don't really believe that this happens.
