Your hair follicles have pigment cells that make melanin, a chemical that gives your hair its color. As you age, these cells start to die. Without pigment, new hair strands grow in lighter and take on various shades of gray, silver, and eventually white.
Hair goes gray when color-producing cells stop producing pigment, says Jeffrey Benabio, MD, a dermatologist at Kaiser Permanente in San Diego. Naturally occurring hydrogen peroxide can also build up in the hair, bleaching the color.
However, sometimes graying hair indicates an illness, especially if it occurs at a particularly young age. Health problems that may be heralded by gray hair include: vitamin B12 deficiency.
King agrees and says that stress hormones may impact the survival of melanocytes in our hair, but there is no clear link between stress and gray hair. Instead, there are just a few small studies that show it may play one of many factors that contribute to this color change.
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.
Griscelli syndrome is an inherited condition characterized by unusually light (hypopigmented) skin and light silvery-gray hair starting in infancy. Researchers have identified three types of this disorder, which are distinguished by their genetic cause and pattern of signs and symptoms.
"Gray hair is a crown of splendor; it is attained by a righteous life." -Proverbs 16:31.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
Stress hair loss, or telogen effluvium, looks like hair falling out quickly from combing, washing, or even just touching the hair. The hair on the scalp may be thinning, but the scalp looks healthy and does not have scales or rashes.
Oxidative Stress: Sleep deficiency can lead to increased oxidative stress in the body, which, in turn, can damage melanocytes, the cells responsible for producing melanin. This damage can expedite the greying process.
To fully achieve a gorgeous shade of grey, you'll need to first bleach your hair and then dye it. Make sure that you're really committed to your new colour before you start.

A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
Silvery hair is a common presentation of rare group of autosomal recessive disorders called Silvery hair syndromes including Griscelli syndrome (GS), Chediak-Higashi syndrome, and Elejalde syndrome.
To reverse grey hair, you need enough melanocyte stem cells (McSCs), which produce pigment cells (melanocytes) for your hair. These stem cells stop working with age, and hair greying is thought to be irreversible when they do [3].
“The glory of young men is their strength, gray hair the splendor of the old” (Proverbs 20:29). There is an interesting transformation that happens as we grow older. We may become physically weaker, but at the same time we become wiser (or at least we should).
And as you age, naturally, these cells start to die. Without the Melanin pigment, new hair strands grow in lighter and lighter, taking on various hues of grey, silver and eventually white.
A damaged hair strand refers to a hair fiber that has lost its natural structure and strength due to various factors such as heat styling, chemical treatments, and environmental stressors. Damaged hair strands may appear dry, brittle, and dull, and can also have split ends and frizz.
Traumatic alopecia — This form of hair loss is caused by hairdressing techniques that pull the hair (tight braiding or cornrowing), expose hair to extreme heat and twisting (curling iron or hot rollers) or damage the hair with strong chemicals (bleaching, hair coloring, permanent waves).
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Marie Antoinette syndrome designates the condition in which scalp hair suddenly turns white.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
In some individuals, the change in color of pubic hair may occur around the age of fifty, but it can happen earlier or later, depending on individual genetic predispositions and lifestyle factors.
As we age, melanocytes decrease in number and less melanin is produced. Fewer melanocytes mean a lack of pigment in the hair, resulting in a silvery-gray color. Now the hair itself is not actually white; it is an optical illusion that results when light is refracted off the hair, creating a silver-like look.
Greying of hair, also known as greying, canities, or achromotrichia, is the progressive loss of pigmentation in the hair, eventually turning the hair grey or white which typically occurs naturally as people age. Greying of hair. Other names.
