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.
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.
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.
Objectives: To assess hair colour and greying in a large world sample of human subjects, and to revisit the validity of the 50/50/50 rule of thumb, which states that 'at age 50 years, 50% of the population has at least 50% grey hair'.
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.
You're probably not going gray.
They found that the timing and extent of grayness depend on genetics and ethnic heritage — and that your chances of going half gray at 50 are less than 24 percent.
The primary — and most scientifically-sound — reason for gray hair is in your genes. This is especially true if you go gray before 20 years old, which is referred to as premature graying. If your parents developed gray hair at a young age, chances are you will, too — and there's not much you can do about it.
While the study concluded that the average age for a woman to go grey is 33, it found redheads lose their colour at 30, brunettes at 32 and blondes at 35. For one in 10 women, those first grey hairs appear by the time they reach 21-years-old, while one in four women find their first grey by the age of 25.
Despite the claims made online and by product marketers, it's not possible to reverse white hair if the cause is genetic. Once your hair follicles lose melanin, they can't produce it on their own. As melanin production slows, your hair turns gray, and then white when melanin production has completely stopped.
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.
Don't assume that grey hair makes you look older
Hair naturally loses pigment as we age, but stylist Paul Falltrick points out that the notion that grey hair makes you look older is increasingly becoming a misnomer: "Grey shades can be stereotyped as ageing, but a clean-looking grey is stunning" he says.
“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.”
Just like one finds grey hairs on the head upon ageing, appearance of grey hair on the eyebrows is also a sign of ageing/premature ageing. While for some, these signs start showing up in the 40's or 50's, some folks encounter the problem of grey hair on eyebrows in their 30's.
Lack of proper sleep and stress are main reason of premature greying of hairs. Such lifestyle increases the ageing process which in turn may affect the hair growth, volume and overall health.
According to a research group at Columbia University if the grey hair was brought on by a stressful event it can go back to its original hair color if that stress is removed from the person's life.
Slowing Down Gray Hair
According to the LiveStrong Foundation, women may begin a vitamin regimen in order to prevent and/or slow the graying process which includes the following vitamins: Vitamin B12, Vitamin E, Vitamin B9, and PABA. This is the recommended protocol: when you eat breakfast, take 2mcg of vitamin B12.
Gray temples likely have genetic origins, related to the way skin is formed in utero. "Local control in different regions of scalp may influence graying," Mirmirani says.
So, he says, "Follow healthy hair habits. Try to avoid repetitive use of heat and chemical treatments which can damage the hair and the pigment cells. Limit exposure to, or protect hair from, toxins and pollutants, and when possible, protect your hair from the sun by covering it up with a hat or scarf."
In those aged 56 to 60, 86 percent had some grey hair, with almost a third of their head having been covered. But not everyone in their 60s had grey hair. Researchers found that 91 percent of 61 to 65-year-olds have, on average, 40 percent of their hair going grey.
It also found that one in 10 people over 60 had no grey hairs at all. Your race can play a part in when you start to notice the first signs of greying. In general, Caucasians start to go grey in their mid-30s, Asians in their late-30s, and Africans in their 40s.
Seventy-four percent of people between the ages of 45 and 65 have grey hair, with an average intensity of 27%. Within this age group, men have more grey hairs than women. The age at which hair begins to turn grey and the increase in grey hair with age appear to be clearly linked to ethnic and geographical origin.
22.7% – 21-25 years old. 18.6% – 16-20 years old. 18% – 26-30 years old. 10.9% – 31-35 years old.
Although there's no such thing as a white hair rubric, it usually follows the 50/50 rule. "It's estimated that 50 percent of the population will have gray hair by the age of 50," says Dr.
