B complex vitamins such as B12, Biotin, and B6 are important for strength and colour of hair. Deficiencies of any of these nutrients are known to promote hair greying. B complex supplements are very useful in preventing greying.
Any deficiencies of vitamin B-6, B-12, biotin, vitamin D, or vitamin E can contribute to premature graying. One 2015 report in the journal Development notes various deficiency studies on vitamin D-3, vitamin B-12, and copper and their connection to graying hair.
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 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.
There isn't a lot of medical data to back it up, but some research does show that magnesium deficiency may be behind some (not all) causes of gray hair. If this is the cause of your greying, then making sure your magnesium stores are optimal could stop or even reverse the greying of your hair.
Dairy and dairy products like curd and cheese are rich in vitamin B12. Since vitamin B12 is essential for making DNA, which is the genetic material found in all cells of the body including hair follicles, a deficiency of it can lead to under-nourishment of hair leading to premature greying.
According to these results, among copper, zinc, and iron, a low serum copper concentration may play a role in premature graying of hairs in our society.
Apples Aside from being an important inclusion in a list of vitamin B12 fruits, apples are also rich in fibre, antioxidants, and flavonoids. Apples also comprise polyphenols that are found in both the peel and the pulp of the nutrient-dense fruit.
They found that noradrenaline, also known as norepinephrine, was key to stress-induced hair graying. By injecting noradrenaline under the skin of unstressed mice, the researchers were able to cause melanocyte stem cell loss and hair graying. Noradrenaline is produced mostly by the adrenal glands.
Specific minerals are needed by the melanocytes to make pigment (a process called “melanogenesis”), such as copper, zinc, iron and calcium (R,R). 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.
POSSIBLE ETIOPATHOGENESIS OF GRAYING
Reversible hypopigmentation of the hair can be seen in nutritional deficiencies protein-energy malnutrition and diseases of chronic loss of protein. Copper and iron deficiency also can cause graying of hair.
If you're looking to boost the amount of vitamin B12 in your diet, you should eat more animal products, like meat, seafood, dairy and eggs. Fortified breakfast cereals are another great way to get more B12. It is possible that your provider may want you to take a vitamin B12 supplement in addition to your diet change.
Stage 1 is decreased levels of vitamin B12 in the blood. Stage 2 is low concentration of vitamin B12 in the cell and metabolic abnormalities. Stage 3 is increased levels of homocysteine and MMA and decreased DNA synthesis resulting in neuropsychiatric symptoms. Stage 4 is macrocytic anemia.
[1] People who regularly take medications that suppress stomach acid for conditions like gastroesophageal reflux disease (GERD) or peptic ulcer disease—such as proton-pump inhibitors, H2 blockers, or other antacids—may have difficulty absorbing vitamin B12 from food.
There are certain foods that also need a cut-down in case of vitamin B12 deficiency. “Some foods and drinks can interfere with vitamin B complex intake like alcohol, caffeine and processed foods, etc should be avoided completely,” Shah added.
Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12, called hydroxocobalamin. At first, you'll have these injections every other day for 2 weeks or until your symptoms have started improving. Your GP or nurse will give the injections.
The Neofollics Anti-Grey Hair Tablets is a natural treatment with an optimal composition of high quality ingredients. It contains no allergens, no artificial colourants and is suitable for vegans.
As a result, when vitamin B12 levels are low, your hair follicles may not be able to grow new hair efficiently. This will result in hair loss. B12 deficiency can also lead to symptoms of anemia, which is linked with low iron levels, hair thinning, and hair loss.
B12 Deficiency Symptoms
Symptoms of low B12 often occur when blood levels drop below 300 ng/l and include hair loss, breathlessness, lack of energy palpitations, bleeding gums, mouth ulcers, tingling in the hands and feet.
