The daily recommended dietary intake of folic acid for adults is 400 mcg (14). Anecdotal evidence suggests that vitamin B5 or pantothenic acid can prevent premature hair graying. It is said to play a key role in melanin production and can restore your natural hair color.
It is purported that when Pantothenic Acid and folic acid are taken together it helps reverse graying by taking the hair back to its original color. Inositol, a substance found naturally in the human body, may encourage the growth and overall health of 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.
Context: 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.
However, the rate of hair colour loss is largely determined by your genes. The chances are that you will experience premature greying if your parents do. However, certain nutritional deficiencies and underlying medical conditions may play a role. In these cases, yes, white hair can turn black again.
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.
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.
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. We require about 500 to 600 mcg per day.
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.
A deficiency in vitamin B9—also called folic acid or folate—is associated with hair turning gray sooner than it should. 1 B9 is important for the production of methionine, an amino acid that's essential for hair color, and also helps with the production of DNA and RNA.
Vitamin B complex, prenatal vitamins, multivitamin tablets are often suggested as a supplement for biotin, zinc and folic acid. Consume tablets every day and you will notice an improvement in your hair's growth and health within two to three months.
Folic acid, also known as vitamin B9, does play an important part in hair growth. It facilitates red blood cell production and helps to maintain good circulation. In turn, this helps the hair by ensuring a plentiful supply of the nutrients needed for healthy growth reach the follicles.
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.
Significantly exceeding this dose, however, can cause illness. In general, the symptoms of vitamin toxicity include nausea, gastrointestinal problems like constipation and diarrhea, hair loss, rashes, and nerve damage.
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.
The hair life cycle of your beard hair is shorter than your head hair. As a result, more melanocytes may be used at a faster rate. Another reason your beard hair appears gray faster than your head is visual. Your beard is front and center on your face, so you'll likely notice every gray hair growing.
In traditional Chinese medicine, fo-ti has been used for centuries as a treatment to keep dark hair from graying and to help maintain natural hair color. Fo-ti, or fo-ti root, comes from the plant Polygonum multiflorum (or tuber fleeceflower), which is a perennial herb native to China.
Collagen may help reduce the appearance of gray hair by supporting the healthy structure of the hair follicle (where the pigment that gives hair its color is produced). When collagen creams or gels are applied directly to the scalp, gray hair can appear darker and less dry.
Rosemary is an essential component in the treatment of hair growth. Rosemary essential oil prevents greying of hair and also darkens the hair that has already turned grey. Moreover, it doesn't even cause much irritation and itching on the scalp after the treatment.
