Low copper levels can lead to premature graying, according to one 2012 study. Good food sources of copper are beef liver, lentils, almonds, dark chocolate, and asparagus. These are superfoods for white hair, helping in its reversal.
Addressing deficiencies
Anyone who has white hair resulting from a vitamin deficiency should consume more foods loaded with those vitamins. For example, seafood, eggs, and meats are good sources of vitamin B-12, and milk, salmon, and cheese are excellent sources of vitamin D.
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.
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.
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.
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.
Most people start noticing their first gray hairs in their 30s—although some may find them in their late 20s.
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.
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.
Dr. Kraleti doesn't recommend plucking or pulling the hairs out. “If there is a gray hair you must get rid of, very carefully cut it off. Plucking can traumatize the hair follicle, and repeated trauma to any follicle can cause infection, scar formation or possibly lead to bald patches.”
Drink six ounces of fresh amla juice every day or massage your hair with amla oil one time each week. Amla is also known as Indian gooseberry. Black sesame seeds (Sesamum indicum). Two to three times a week, eat a tablespoon of black sesame seeds to slow down and possibly reverse the graying process.
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.
Health Risks
Caffeine dependence is classified as a disorder and has real negative consequences. It is linked to age-related diseases such as osteoporosis and premature aging. Because it also contributes to cellular aging, it can cause early wrinkles, gray hair, and hair loss.
Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair. Add citrus fruits like oranges, grapes, pineapple, and melon to your diet. Also eat vegetables like potatoes, carrots, beans, etc. Non vegetarians can try adding red meat, chicken liver, fish, and eggs to their diet.
The vitamins inside stop hair from greying
However, the condition can be reversed by simply increasing the amount of the vitamin you intake and, luckily, blueberries are an excellent source of it.
Gray hair is one of the universal signs of advanced age. More likely than not, at some point in your life, your hair will start to go gray. Some individuals can maintain hair color well into their older age, but most do not.
It's most common for graying to begin in your 30s, though some people spot a few grays in their 20s. If you think you're going gray unusually early, there are a number of possible reasons why. Smoking, for one, has been linked to the early onset of gray hair.
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.
1. When do most women go grey then? "Most women who are in their 30s should see a few grey hairs, but by the time they get into their 50 most women would expect to have more than 50% of their scalp hairs turn grey."
Aside from the time investment of a salon session, there's how long it takes to fully transition to gray hair, which is anywhere from six months to a year, Ferrara says.
Other important minerals for healthy hair are selenium and magnesium. People who are deficient in these important minerals have more risk of their hair turning gray.
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.
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.
