Why Does Hair Turn Gray?

Have you ever watched someone trying to cover up gray hair by dyeing it? Or maybe you wonder why your grandad has a full head of silver hair when in old pictures it used to be dark brown? Getting gray, silver, or white hair is a natural part of growing older, and here’s why.

Each hair on our heads is made up two parts: a shaft ---- the colored part we see growing out of our head and a root ---- the bottom part, which keeps the hair anchored under the scalp.

The root of every strand of hair is surrounded by a tube of tissue under the skin which is called the hair follicle. Each hair follicle contains a certain number or pigment cells. These pigment cells continuously produce a chemical called melanin which gives the growing shaft of hair its color of brown, blonde, red, and anything in between. The dark or light color of someone’s hair depends on how much melanin each hair contains.
As we get older,the pigment cells in our hair follicle gradually die. When there are
fewer pigment cells in a hair follicle, the 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 able to produce less melanin. Eventually, the hair will look completely gray.

People can get gray hair at any age. Some people go gray at a young age, whereas others may be in their 30s or 40s. 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 as our parents or grandparents first did.
