Scientists don't know exactly why some people go gray early, but genes play a large role. Also, a vitamin B-12 deficiency or problems with your pituitary or thyroid gland can cause premature grayingNutritional deficiencies like vitamin B12 deficiency, severe iron deficiency, chronic protein loss, copper deficiency are often found associated with premature greying of hairs. Other factors that have been incriminated are low serum ferritin, and low serum calcium and vitamin D3 levels.https://en.wikipedia.org › wiki › Premature_greying_of_hair
Vitamin B12 deficiency may cause gray hair
An older study found that a deficiency in vitamin B12 deficiency can cause premature gray hair. Researchers found that about 55 percent of study participants with pernicious anemia experienced gray hair before they turned 50.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
There are no treatments that are proven to treat (or reverse) gray hair. As researchers learn more about how the graying process happens, they may develop effective medications and treatments for gray hair.
Silvery strands are one of the more conspicuous signs of aging. That said, getting gray hair doesn't necessarily mean that you're closer to the end of your life span than anyone else your age.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
“Plucking a gray hair will only get you a new gray hair in its place because there is only one hair that is able to grow per follicle. Your surrounding hairs will not turn white until their own follicles' pigment cells die.”
Stress can cause hair to gray prematurely by affecting the stem cells that are responsible for regenerating hair pigment.
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.
Vitamin B-12 deficiency is one of the most common causes of prematurely graying hair. Researchers have noted that vitamin B-12 deficiencies are often concurrent with folic acid and biotin deficiencies in people whose hair has started to turn gray early.
The pigment in our hair is caused by melanin— the same pigment that is also responsible for our skin color. Gray hair is caused by a loss in melanin, whereas white hair does not have any melanin at all. As you age, your hair produces less and less melanin that leads your hair to appear gray, and then eventually white.
Having lower levels of vitamins and minerals can be associated with getting gray hair prematurely, according to a Cosmoderma article published in December 2021. The study noted that a lack of calcium, copper, ferritin, and zinc could lead to early gray hair. Another possibility is a vitamin B12 deficiency, Dr.
Lack of proper sleep and stress are main reason of premature greying of hairs. Such lifestyle increases the ageing process which in turn may affect the hair growth, volume and overall health.
Even stranger, the belief that shock can turn our hair grey has roots in reality. “It can, not overnight, but over weeks or months,” says Daniel Nettle.
Eat black food
Black beans, brown rice and black sesame can be good for your hair colour. And it's not just because they are black. These food items contain natural colour pigments that can be good for your hair. Other dark coloured food include black fungus, mushrooms and dark seafood and meat.
Grey hair and genetics
The average age for grey hair varies greatly, and one of the main causes of grey hair in your 20s is genetics. The age at which a person's hair turns grey is influenced by the IRF4 gene, and one specific variant (rs12203592) is a marker for premature greying.
While the study concluded that the average age for a woman to go grey is 33, it found redheads lose their colour at 30, brunettes at 32 and blondes at 35. For one in 10 women, those first grey hairs appear by the time they reach 21-years-old, while one in four women find their first grey by the age of 25.
On occasion, gray hairs can be a sign of illness, such as thyroid disease or alopecia areata (a common autoimmune disorder). If you have other tell-tale signs, such as balding patches, let your healthcare provider know. However, don't panic — these are rare and little cause for concern.
