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.
With the right nutrients such as B vitamins, vitamin C, L-methionine, copper, folate, calcium, iron, zinc, and antioxidants, you can stop further greying of hair.
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.
Intake of foods rich in vitamin B12 like meat, eggs, milk, and fish can help in gray hair reversal. A daily dosage of 2.4 mcg is recommended for most adults (13).
Melanin deficiency is associated with vitamin deficiency. That's why you need to increase your vitamin intake through your food or vitamin supplements. Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair.
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.
When zinc levels are low, hair loss, delayed growth, the appearance of grey hairs and various types of immune deficiencies may be observed.
Hormonal Imbalances
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.
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.
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.
Key points about vitamin B12 deficiency anemia
Without enough red blood cells, your tissues and organs don't get enough oxygen. Without enough oxygen, your body can't work as well. Symptoms include weak muscles, numbness, trouble walking, nausea, weight loss, irritability, fatigue, and increased heart rate.
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.
How to raise your B12 levels fast. The most common way to treat B12 deficiencies is by adjusting your diet. If this is unsuccessful, vitamin supplements may be recommended. 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.
In addition to food, both vitamins B6 and B12 can be found in a range of supplements which may help you to prevent grey hairs and restore your natural colour.
Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet. A diet that includes meat, fish and dairy products usually provides enough vitamin B12, but people who do not regularly eat these foods can become deficient.
Will Hair Grow Back From B12 Deficiency? Yes! Your hair will grow back as soon as you treat the deficiency. On restoration of vitamin B12 in your body, your hair cells will replicate adequately and support your hair follicles to grow healthy hair.
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 graying that's reversible if the problem is corrected, Benabio says.
Eating vitamin C–rich foods like citrus, berries, and leafy green vegetables may optimize melanin production.
