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.
B-6 may help restore hair to its original color following an illness or deficiency. Para-Amino benzoic Acid (PABA) and Pantothenic Acid are part of the family of B-complex vitamins. Both of these vitamins are available at health food stores and pharmacies. Use them to postpone the onset of graying.
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.
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.
Now a new study confirms what many have suspected and offers a bit of hope: stress can lead to gray hair and taking stress away appears to reverse the process, allowing white strands to return to the natural color at the root.
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.
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.
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.
Biotin has many benefits. It triggers hair growth, it treats hair loss related disorders, and it thickens and strengthens the hair. One of our favorite beneficial effects of Biotin is that is can reverse premature greying of hair.
If you want to get darker hair and prevent gray hair completely, use coffee on regular basis. Simply take one cup of coffee and mix it with one cup of water. You can also add 2-3 spoons of coffee powder and allow it to dissolve. Let the coffee powder dissolve completely and then apply on your hair.
According to anecdotal data, omega 3 may help prevent gray hair. Eat a balanced diet that is high in omega-3 fatty acids. Additionally, you can use oils high in omega 3, such as emu oil. Massaging this oil onto your scalp may aid in rejuvenating the hair follicles and pigment-producing cells called melanocytes.
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.
It might take 2 to 3 months or even a year to recover depending on the age. This is because after a certain age the scalp cells lose their renewal and absorbing abilities and also melanin production stops.
Vitamin D
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.
Melatonin is a natural substance made by the body to prepare us for sleep. Melatonin could reduce hair graying and improve hair pigmentation mainly because of its protective effects on cells, including stem cells (R,R).
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.
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.
Eating vitamin C–rich foods like citrus, berries, and leafy green vegetables may optimize melanin production. Taking a vitamin C supplement may help as well. Shop for vitamin C.
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.
Vitamin deficiency
If your body is vitamin deficient, then that is considered to be a major cause behind premature greying. Vitamins such as B6, B-12, D, E and biotin are extremely crucial for the overall health of your hair, including in keeping those annoying greys in check.
Since baking soda is a scrubbing agent, washing your hair with it can gradually strip the dye from your locks. Baking soda can lighten all hair colors, but it might take a few washes to get your hair to the desired color.
And while it may seem intuitive that stress can accelerate graying, the researchers were surprised to discover that hair color can be restored when stress is eliminated, a finding that contrasts with a recent study in mice that suggested that stressed-induced gray hairs are permanent.
Although this may seem like a permanent change, new research reveals that the graying process can be undone—at least temporarily. Hints that gray hairs could spontaneously regain color have existed as isolated case studies within the scientific literature for decades.
