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.
It turns out that, among people who are nutrient deficient, supplementing with vitamin B-5, high-dose para-aminobenzoic acid, iron, or vitamin B-12 might help reverse gray hair.
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.
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.
While you cannot delay when you are genetically programmed to turn grey, Anabel explains, 'if you have a Vitamin B deficiency, adding foods rich in B vitamins, or a supplement containing them, may be useful in stopping premature greying. ' Additionally, lifestyle choices, such as smoking, can play a part in your greys.
When there isn't enough vitamin D in your body your hair may turn grey or white. One study published in The International Journal of Trichology found that children who experienced premature hair greying had low vitamin D levels.
While vitamins cannot reverse gray hair, they can slow down the process. Eating a diet rich in vitamins D, B5, and B12, iron, and calcium can prevent your existing hair from turning gray.
Vitamin B-12 is the most common culprit, with folate, copper, and iron deficiencies increasing your risk, too. Dietary supplements may help these deficiencies and you might see your natural hair color start to grow back after several weeks.
Iron deficiency can also lead to grey hair. Iron is a vital mineral that helps create haemoglobin – the substance found in RBCs. Lacking an adequate amount of iron means lesser blood cells, which leads to insufficient oxygen supply to your scalp. Naturally, this causes grey hair at a young age.
Vitamins B6 and B12 have also been proven to boost melanin production. Goddard says that vitamin B6, also known as pyridoxine, has been found to trigger the production of enzymes and chemical reactions that boost the metabolism of the hair proteins (keratin and melanin) in the hair follicles.
Some studies have demonstrated that grey and ageing hair can recover its original colour when nourished by diets rich in zinc and supplements formulated with this element. As an additional benefit, zinc also helps eliminate the dandruff present on the scalp.
Iron: beef, dark leafy greens, fortified cereals, oysters, white beans, dark chocolate, lentils. Copper: beef liver, oysters, unsweetened chocolate, potatoes, shiitake mushrooms. Selenium: Brazil nuts, tuna, halibut, sardines, shrimp.
Many men and women experience hair loss and early graying when their hormones are no longer balanced. Hormone changes can occur for many reasons such as stress, significant weight loss or weight gain, an illness you've had, or pregnancy.
Vitamin C prevents hair from thinning, improves hair texture, and cures damaged hair. This vitamin also promotes hair growth. Vitamin C deficiency in the body turns hair to grey prematurely. In addition, this vitamin deficiency causes dryness in the hair.
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.
If genetics or aging is the cause, nothing can prevent or reverse the process. However, treating graying hair could allow color pigmentation to return if the loss is due to a medical condition.
The age at which you go gray is also determined by your genetics. So, if you have a parent who went gray early, then it's likely you will too. It's not possible to reverse or treat gray hair.
Meat (pork, beef, etc.), poultry (chicken, turkey, etc.), and fish (tuna, salmon, etc.) are excellent sources of vitamin B3, vitamin B6, and vitamin B12. They also contain other important minerals such as potassium, chromium, iron, selenium, and zinc.
Bananas also contain fibre and potassium. It helps manage blood pressure, reduce stress, and relieve constipation and ulcer problems. The fruit also helps regulate body temperature. Another fruit that is rich in vitamin B12 is blueberries.
Causes of vitamin B12 deficiency include: Not enough vitamin B12 in diet (rare, except with a strict vegetarian diet) Diseases that cause malabsorption (for example, celiac disease and Crohn disease) Lack of intrinsic factor, a protein that helps the intestine absorb vitamin B12.
