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.
Grey hair and genetics
The average age for grey hair varies greatly, and one of the main causes of grey hair in your 20s is genetics. The age at which a person's hair turns grey is influenced by the IRF4 gene, and one specific variant (rs12203592) is a marker for premature greying.
Nearly one in 10 people over 60 years of age is "naturally blessed" to have not a single grey hair on their head, says a new research conducted in more than 20 countries.
False. This isn't necessarily true for everyone, says Sobel. By the time people are in their thirties, most have a few strands of gray hair naturally. While some may continue to gray with each passing year, others may just stall at those few strands of gray for years—or even decades—to come.
Gray hair is one of the universal signs of advanced age. More likely than not, at some point in your life, your hair will start to go gray. Some individuals can maintain hair color well into their older age, but most do not.
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.
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.
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.
Hair-graying onset 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. Caucasians and Asians typically experience damage to the distal hair shaft, while African-Americans see damage occurring closer to the hair root.
It can be inherited from either parent. The color of our hair is determined by the form of hair pigment that we have. The pigment is actually produced along the hair shaft, and there are two main forms of hair pigment. There's eumelanin and pheomelanin.
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.
Silvery strands are one of the more conspicuous signs of aging. That said, getting gray hair doesn't necessarily mean that you're closer to the end of your life span than anyone else your age.
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.
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.
It's a sign of the aging process, and there's absolutely nothing wrong with that. According to Harvard Medical School, there are many reasons why hair turns gray, but overall gray hair is mainly genetic and it's not an indicator of poor health.
In humans, most gray hair is not related to stress. In fact, hair doesn't actually "turn" gray at all. Once a hair follicle produces hair, the color is set. If a single strand of hair starts out brown (or red or black or blond), it is never going to change its color (unless you color your hair).
As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color — like gray, silver, or white — as it grows.
Caucasians tend to go gray earlier — and redheads earliest of all.
Like hair on your head, your pubic hair may also thin out with age. If you've got a lush patch now, many factors could thin it, make it go gray or white, or even cause it to bald. For ladies, menopause is one of them. For men, it's the natural aging process and dropping testosterone levels.
Pubic hair holds on to residual urine, vaginal discharge, blood and semen. Bacteria line up all along the hair shaft just lunching it up and creating odor. (Very appetizing, I know.) Trimming your pubic hair reduces that surface area for bacteria, thus reducing odor.
Aging is the most common reason your pubic hair turns gray or white. And while you can't change your genes and the normal aging process, you can slow down pigment loss and those white pubic hairs by eating properly, quitting smoking, and decreasing stress in your life.
"While it's a natural part of aging for most of us, not everyone automatically turns gray when they hit the age of 50," she says. "Some people in their 80s don't have gray hair yet, while others get white hair in their late teens," she adds.
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.
Since baking soda is a scrubbing agent, washing your hair with it can gradually strip the dye from your locks. Baking soda can lighten all hair colors, but it might take a few washes to get your hair to the desired color.
