And when the mice were stressed acutely, their nerves were flooded with norepinephrine. When that happened, all the melanocyte stem cells got programmed to make melanocytes. So there were no more stem cells left to make melanocytes in the future. Now, this didn't happen overnight, but a relatively short period of time.
Science explains what causes this natural transformation
Vitiligo occurs when cells that produce melanin die or stop functioning, resulting in a loss of skin color in patches over the body that usually grow over time. With alopecia areata, patches of hair — especially colored hairs — can be suddenly lost, which may result in more noticeable gray hair. Shmerling noted in a 2017 article that the result could explain why some people seem to turn gray overnight.

Harvard Health Ad Watch: New drug, old song, clever tagline
Split ends and dry hair are just two casualties of overstyling. It can be long and wavy, short and straight, frizzy and unmanageable, or smooth and shiny. Hair comes in many different lengths, styles, colors, and textures.
The Smoking Link
Purple shampoo, in particular, color-corrects warm tones in blonde hair. Basically, this is a fancy way of saying that it helps reduce brassiness. These cleansers are ideal for light-colored hair especially if you go gray or white. Overuse of a purple-tinted shampoo can turn your hair muddy, reduce its brightness, and make it look darker according to Hazan.

Try and use it once a week, because better sultry than sorry. When you spot your first gray hairs, step away from the tweezers. While it may be tempting to pull out a silver strand or two, doing so can actually get in the way of your gray greatness and make your hair appear thinner. "Plucking, in some cases, can cause inflammation of the root of the hair, leading to damage to the follicle, helping the hair look like it's coming in thinner," says Zeichner. "Most of the time, plucking does not truly thin out the hair, but it appears thinner as it grows in because a new hair is formed with a thin edge.
For now, the next step is to look more carefully at the link between stress and graying. So basically, as we age our cells produce less melanin, which leads to gray hair. But, if you go gray much earlier than anticipated (say, at age 20 instead of in your late 30s or 40s), there might be something more at play.
Facts That Will Change Everything You Think About Going Gray
But over the course of this study, the researchers learned that McSCs actually move between microscopic compartments in your hair follicle. Each compartment might give the MsSC a slightly different protein signal, which allows the cell to oscillate between different levels of maturity. That's largely unlike how other stem cells operate — that is, maturing until they die. Moreover, Dr. Tobin suggests that hair turns gray because of age and genetics, in that genes regulate the exhaustion of the pigmentary potential of each individual hair follicle. This occurs at different rates in different hair follicles.
It’s possible these exposures trigger changes in hair pigmentation. It's been suggested that at some time 90% of women over 50 dye their hair. When you finally decide to go gray, you can dye your hair white, but that would be a shock. You could color your hair but put gray highlights and then let it grow out. You could color your hair gray with colored highlights and let it grow out. Best of all, you shouldn't even listen to me because I'm clueless.

Unlike hair loss, however, for which there has been great strides in treatment, “there’s nothing you can do to modify the rate at which you turn gray or when it will happen,” says Dr. Korda. With that said, follow the general guidelines for a healthy lifestyle, he suggests, noting the small studies in people indicating that stress and nutrition may play a role in premature graying. For starters, you want to use a blue or purple-hued shampoo and conditioner several times a month to keep your color strong. “Clarifying and purple shampoos can keep the gray or white hair brighter and will also help prevent the yellowing that comes from the sun,” says Leppard.
In fact, general aging and even your genes could have a lot more to do with your silver strands than you might think. And underlying health conditions like vitamin deficiency or alopecia could even be a factor. Whether you discovered your first silver strand or you’ve decided to let your natural hair color shine, it’s normal to find yourself wondering, why does hair turn gray? And while we’ve touted ways to embrace and style your gray hair, the science behind why white and gray strands occur is actually quite interesting. If genetics or aging is the cause, nothing can prevent or reverse the process. However, treating graying hair could allow color pigmentation to return if the loss is due to a medical condition.
Instead, try a light anti-frizz shine spray, to keep things locked down and smooth. Speaking from experience, during my brief foray into grayness, I swear by Alterna’s Bamboo Smooth Kendi Dry Oil Mist, which gives your hair a silky sheen without weighing it down at all. "A good haircut is essential. Precision-shaping paired with deep hydration will save the day," says Marris Ambrose, color director at Julien Farel Restore Salon & Spa Color in New York City.
As for me, I scrutinize the ashy strands that have popped up in my 40s—intruders amongst the inky curtain of my hair—and resist the urge to pluck them. You can also use temporary at-home coloring techniques to disguise roots. Mincho Pacheco, master hairstylist and colorist at James Joseph salon, recommends using a little bit of makeup to cover grays. There are many reasons people experience graying, but a lot of times it simply comes down to natural aging and genetics. This means that it just happens because it’s a commonality within your family genes. Check when your relatives or parents went gray and see if it matches with your timeline.
That’s partly because of a gradual decline in the number of stem cells that mature to become melanin-producing cells. The cells may wear out, become damaged, or lose the support systems meant to keep them working. Genes are also a factor, since they help control melanin production. A team of researchers says it has identified the root cause as trapped stem cells — and that means new tips for naturally fending off grays from your mane could be coming soon. Environmental stressors, such as pollution, smoking, and ultraviolet light (UV), speed up the hair graying process by producing reactive oxygen species (ROS) that damage melanocytes. However, as hair ages, increasing numbers of the cells do not migrate back to their niche.
