Unfortunately, the answer is no. “The point at which one starts to go grey is dependent on each person's individual genetics and cannot be slowed down in any way,” says Dr. Shadan.
"Ensure you have an adequate level of Vitamin D3 and Vitamin B12, since deficiencies in either of these may accelerate graying," explains Lain. Other important micronutrients for healthy hair include vitamin E, vitamin A, zinc, iron, copper, selenium and magnesium.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
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.
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.
A new study shows that stress really can give you gray hair. Researchers found that the body's fight-or-flight response plays a key role in turning hair gray. Your hair color is determined by pigment-producing cells called melanocytes.
If you add the right hair colour, your 'grey' hair will act as highlights, giving you a completely new look that will get you noticed for all the right reasons. Professional colourists usually recommend a darker shade for your roots and a lighter shade that matches your natural hair for the rest.
But does any supplement really help? 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. However, these vitamins are unlikely to be beneficial among people with adequate levels.
Foods to increase melanin in the hair
Copper-rich foods such as various kinds of nuts, mushrooms and meat liver also promote follicular melanin synthesis. Sources of vitamin A, C, and E including carrots, papaya, eggs, citrus fruits, sunflower seeds, almonds, peanuts and pistachios can improve the health of your hair.
Your hair follicles produce less color as they age, so when hair goes through its natural cycle of dying and being regenerated, it's more likely to grow in as gray beginning after age 35. Genetics can play a role in when this starts.
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.
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.
"This is a predestined thing—it's genetic and can happen at any age." With that said, she cites the late thirties as the time at which pubic hair typically begins to gray. Some health factors, however, may accelerate the graying process, says dermatologist Joshua Zeichner, MD.
Just like the hair on the head, the hair on the rest of the body, including the pubic area, is subject to graying. As people age, their skin produces less melanin. Melanin is the pigment responsible for giving skin and hair its color. The hair follicles contain melanin.
Not everyone will lose their pubic hair. If you keep your pubic and body hair after the menopause, it will likely turn gray, just like the hair on your head. And you may also notice more hair growing in other areas, such as the chin and face.
Dr. Jennifer Chwalek: The process of hair changing from darker color to white or gray with age is mainly due to genetics. It can be inherited from either parent.
Substantially More Grey Hair
om weak or dead hair follicles, lack of a proper sleep cycle can also cause your hair to grey faster than it would normally. That's because the hormonal imbalance that follows when you're not sleeping properly, makes your body produce less eumelanin, the pigment that makes your hair black.
It's most common for graying to begin in your 30s, though some people spot a few grays in their 20s. If you think you're going gray unusually early, there are a number of possible reasons why. Smoking, for one, has been linked to the early onset of gray hair.
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.
Dairy products such as milk, cheese, yogurt, etc. are rich in vitamin B12, calcium, protein, and various other nutrients that aid the production of melanin. Yogurt in particular is probiotic and rich in antioxidants. Eggs are abundant in protein which the body requires to maintain good health of our hair.
