It has long been thought that reversal of gray hair on a large scale is rare. However, a recent study reported that individual gray hair darkening is a common phenomenon, suggesting the possibility of large-scale reversal of gray hair.
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.
''We discovered that in normal people without any special treatment, grey hairs are actually reversible,'' Dr Picard said.

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.
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.
If you're looking at how to increase melanin in hair, you must include in your diet, melanin rich foods and foods that are rich in vitamins. o Vitamin A – stimulates the oil-producing glands in the hair follicle and keeps the hair moisturized. Found in carrots, kale, spinach and sweet potatoes.
This period, when graying has just begun, is probably when the process is most reversible, according to Paus. In those with a full head of gray hair, most of the strands have presumably reached a “point of no return,” but the possibility remains that some hair follicles may still be malleable to change, he says.
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.
Melanin is what gives your hair (and skin) its natural color. People of African descent, Thai, and Chinese people, go grey more slowly.
Yes. Stress has been shown to speed up signs of aging — including gray hair. When you're stressed, your body has a fight-or-flight response and releases a hormone called norepinephrine. This causes the melanocytes — the cells that produce melanin — to move out of your hair follicles.
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.
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.
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.

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.
Studies indicate that reversing grey hairs can take as little as three days; however, the amount of time can fluctuate depending on one's age and other factors such as stress, diet, lifestyle and exposure to environmental toxins and pollutants.
Vitamin B6 is involved in the production of melanin, the pigment that gives hair its color. Ensuring adequate intake of this vitamin may help to maintain melanin production and delay premature graying.
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.
The bottom line. When and how thoroughly your hair turns gray is influenced mostly by the genes you inherit from your parents. Though stress may play a role in the process, it would be more helpful to look to past generations rather than your current stress levels to help you predict when or if you'll go gray.
So, gray hair is not actually a color resigned to the elderly. Gray hair is a natural color that many young people are masking. And, with the right hairstyle, gray hair doesn't have to look frail or frumpy.
