You don't have to be old to get gray hair. It's just a natural change in your hair follicles to change color as you age.

I've had white hair ever since I was a teenager. And I'm still in my early 20's. It's not a matter of age per say that causes the pigment to be lost in hair.

Each hair on our heads is made up of two parts:

* a shaft - the colored part we see growing out of our heads

* 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 that is called the hair follicle (say: fah-lih-kul). Each hair follicle contains a certain number of pigment cells. These pigment cells continuously produce a chemical called melanin (say: meh-luh-nin) that gives the growing shaft of hair its color of brown, blonde, red, and anything in between.

Melanin is the same stuff that makes our skin's color fair or darker. It also helps determine whether a person will burn or tan in the sun. 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 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. Just in case, try not to freak out your parents too much. You don't want to be blamed for any of their gray hairs!

The easy answer is that hair loses pigment as you get older. People with white hair have no pigment whatsoever. People with gray hair still have some. If you want to learn more there is a lot of information at:

There was a funny joke in the paper. A little girl asked her mom why she had gray hairs. Her mom said,"When you misbehave, mommy gets a gray hair." The little girl said," Is that why grandma has all them gray and white hairs?" I thought it was funny. I can't remember the whole thing, but I think i got it right.

Lack of nutrition in the body, so the body starts to wither away like a plant does without enough water, good soil, etc....

If an elder would start taking garlic everyday, the hair would eventually start to turn back to its original color!

Part of aging process determined by the thing called "DNA" which is a possibility, but they are still studying and researching on that part of the grey hair problem. I wonder why I got it so early, and I am not even 50 yet. I got my first grey hair when I was 16 and it just gradually increased over a period of time. Now I am in my mid 30's and my hair looks like salt 'n' pepper and it sucks. Now, I have to dye it to look my age. I think it might be due to world's pollution in the air we breath and eat which is affecting our DNA that alters the process of hair color. I really don't know, it is really a guess.
