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.
Most people start noticing their first gray hairs in their 30s—although some may find them in their late 20s.This period, when graying has just begun, is probably when the process is most reversible, according to Paus.
It's not possible to reverse or treat gray hair.
Scientists still don't know why some people turn gray early, late, or not at all, although they suspect genes, nutrients and possibly the immune system play a role in depleting melanocyte stem cells.
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.
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.
In time, everyone's hair turns gray. Your chance of going gray increases 10-20% every decade after 30 years. Initially, hair is white. It gets its natural color from a type of pigment called melanin.
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.
The 80-year-old man who still has a full head of hair... and not one grey one. When strangers mistake him for a man 30 years younger, Ron Williamson doesn't turn a hair. He explains that he is in fact 80 - but his luxuriant dark-brown mane refuses to show any sign of age.
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.
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 age you go gray is determined primarily by genetics, so if one or both parents went gray at an early age, you would be more likely to go gray at a younger age as well. Smoking can also accelerate color change, and early graying could be a sign of autoimmune, thyroid or heart disease.
Normal aging is the biggest culprit.
"Fifty percent of the population has about 50% gray hair at age 50," says Dr. Anthony Oro, professor of dermatology at Stanford University. And like skin, hair changes its texture with age, says Dr.
When should I go gray? That's a question a lot of us ask ourselves as we start getting older. Cosmetologists and colorists, as a general rule of thumb, advise going gray when 80% of your hair is white or gray, or when your hair starts feeling increasingly dry and brittle.
Eating more antioxidants
Share on Pinterest Eating a diet with lots of antioxidant-rich foods, including vegetables and fruits, may help to prevent hair from graying. A person's diet plays a part in preventing white hair. A diet rich in antioxidants can reduce oxidative stress.
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.
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.
Neutral shades like soft blonde, mushroom brown, light copper, and caramel blonde balayage are the easiest to blend gray into (and maintain over time without wanting to shave your hair off).
Shaskank Kraleti, M.D., explain the medical science behind this myth. “Plucking a gray hair will only get you a new gray hair in its place because there is only one hair that is able to grow per follicle. Your surrounding hairs will not turn white until their own follicles' pigment cells die.”
Pollutants and toxins can cause you to grey faster, according to the Library of Congress. These chemicals generate free radicals-or oxidative stress-that damage melanin production and speed hair aging, studies suggest. But once hair grows out of the follicle, it's dead, adds Dr. Day.
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
