why does your hair go grey?

Answer 1

Each hair contains a finite number of pigment cells (the pigment being melanin, same as in your skin) and as we get older the follicles lose the ability to produce this pigment. The colour of your hair before it greys depends on how much melanin the follicle has.

Answer 2

The change in hair color is caused by the gradual decrease of pigmentation that occurs when melanin ceases to be produced in the hair root, and new hairs grow in without pigment. Two genes appear to be responsible for the process of greying, Bcl2 and Mitf. The stem cells at the base of hair follicles are responsible for producing melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes hair to begin going grey.

There are no special diets, nutritional supplements, vitamins, nor proteins that have been proven to slow, stop, or in any way affect the graying process, although many have been marketed over the years.

Answer 3

Hair turns gray as we age because the follicles at the base of the hair shaft cease to produce melanin. Each follicle contains a finite number of pigment cells. These pigment cells produce melanin, a chemical that gives the hair shaft (the visible strands) its color (black, brown, blonde, red, and all shades in between.) The darkness or lightness of your hair depends on how much melanin each strand contains. Melanin is the same pigment that makes skin tan upon exposure to the sun. With age, the pigment cells in the follicle gradually die off. As they do so, that strand will no longer contain as much color and will show up as silver, gray, or white as it grows. Eventually, all the pigment cells will die and the hair becomes completely gray. The age at which you go gray is determined by your genes. A ballpark guess can be made by observing the ages at which your parents or grandparents went gray. Some people go gray at young ages--as early as high school--whereas some may not go gray before their forties or fifties. For example, most Caucasian women show their first gray hairs during their mid thirties. Graying typically occurs over a long time. From the time that a person notices the first gray strands, it can take ten years or more to complete the process. While genetics is the most common cause of gray hair, other things can contribute to graying. Lack of B vitamins (particularly pantothenic acid, poor nutrition, anemia, (lack of iron in the blood), thyroid problems, and even smoking can contribute to graying. Smokers are believed to gray at an earlier rate because smoking depletes oxygen in the bodies tissues. Treatment for diseases, such as cancer, or AIDS, can also cause hair to turn gray. It has been said that a shock can cause people to go gray overnight but that theory has generally been discounted. Although parents often like to claim that the stess of having children has caused them to go gray, this theory has also been discounted.

Answer 4

it happens because of loss of the natural pigmentation which is part of our growing mature process. Extra stress and lack of good nutrition, can speed the process. Some people are however more prone to grey hair from an earlier age.

Answer 5

Graying hair has been linked in nutritional research to a copper/manganese deficiency, and in some cases, a genetic inability to use either mineral properly.

Keep in mind that one of the most frightening and extreme reports on the lack of minerals in American soil was released more than 50 years ago!

Many livestock and horse-show pros use minerals to restore luster and color to their prize animals' coats.

Let's say you couldn't get ANY calcium, ANYwhere, EVER. Good luck making bones or teeth!

Copper has been linked to the health of the melanocyte and its ability to make color.

Within time, more and more of these "mysterious" ailments, concerns, and diseases from which we suffer will be revealed to be nothing more than nutritional deficiencies...

Some thyroid disorders can be cured, but many require lifetime treatment. Learn here https://tr.im/RUKBH
For example, sometimes early stage thyroid cancer can be cured by surgery to remove the thyroid gland, but you will need to take thyroid hormone medication afterwards for the rest of your life. Goiters can also be surgically removed and do not always recur after surgery. In most cases, thyroid disorders need treatment over a lifetime. However, with treatment most people with thyroid disorders can live normal, healthy lives.
