A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
Unfortunately, there is no scientific evidence to suggest that increasing vitamin B12 intake can reverse existing gray hair. Hair that has already lost its pigment is unlikely to regain its natural color.
A: While there is no conclusive evidence that Vitamin B12 can reverse grey hair, it may help prevent premature greying by supporting overall hair health. Adequate levels of Vitamin B12 contribute to healthy hair growth and may help maintain hair color.
Pigment cells do not come back. Once hair turns grey or white, it is not ever going to turn back into brown, red, or black, or whatever your natural color was.
One of the most frequent causes of premature hair greying is a vitamin B-12 deficiency. Researchers have found that in persons whose hair has already begun to grey early, vitamin B-12 shortages frequently coexist with folic acid and biotin deficiencies.
A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12.
The average age of onset of hair graying appears to be mid- to late forties; however, this varies with race, with the average age for Caucasians being mid-thirties, that for Asians being late thirties, and that for Africans being mid-forties.
You can take a supplement that contains these vitamins or you can supercharge your diet with foods high in B12 and B6. Eating beetroot, sprouts, eggs, fish, cheese, soy and starchy vegetables are healthy ways you can increase melanin in your hair.
Melanin is what gives your hair (and skin) its natural color. People of African descent, Thai, and Chinese people, go grey more slowly.
Low B12 allows folate levels to rise, which has been linked to hair loss. Research indicates that correcting a vitamin B12 deficiency can help treat hair loss and stimulate growth. However, the condition may become irreversible if prolonged deficiency causes permanent follicle damage.
It's not possible to reverse or treat gray hair. But, with advancing research, this may be an option in the future.
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.
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
Gray hair is a natural course of aging; however, it may not be an inevitable or permanent process. Medications which target inflammatory cytokines, such as psoralen and cyclosporin, or stimulate melanogenesis, such as imatinib or latanoprost, have been reported to induce gray hair repigmentation in rare cases.
That said, certain conditions may temporarily restore pigmentation. For example, if greying is caused by a vitamin deficiency, stress, or an underlying medical condition, addressing these issues may slow or even partially reverse greying. However, the complete reversal of naturally aged hair remains a challenge.
While moderate caffeine consumption is generally safe, excessive intake may negatively impact hair health. Potential Effects of Caffeine on Hair 1. Hormonal Imbalance: Caffeine can disrupt hormonal balances, particularly affecting the thyroid gland. Hormonal changes can contribute to hair graying, thinning, or loss.
Typically, White people start going gray in their mid-30s, Asian people in their late 30s, and Black people in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
While sunlight is extremely important for our body, an extreme level of sun exposure can damage your hair's melanin production. UV rays can strip off the natural shade, destroying the melanin of your hair. Your hair becomes lighter in colour.
Aging decreases the synthesis of melanin, which is the pigment that gives hair its natural color. Free radicals can accelerate this process, leading to premature gray hair. Since collagen has antioxidant properties that can combat free radicals, increasing your collagen intake may help prevent or slow down graying.
When melanocytes stop producing pigments altogether, the result is completely white hair strands. It's possible to have both of these natural processes going on at the same time for a blend of white and gray hair.
There's no hard-and-fast rule about when (or if!) you should stop coloring your hair and go gray; it's ultimately a personal choice.
We have previously published findings that, after the age of 50, humans are seldom with- out gray hair. At this age, around 50% of men and 30% of women are moderately or totally gray haired.
