Once the new hair starts to grow, these melanocytes once again ensure that pigmentation is available. But when the melanocytes are damaged or absent, the hair that is produced lacks color and can look gray or white. Hair progenitor cells are reported to release a protein called stem cell factor, which is a requirement for the production of pigment by melanocytes.

Ice packs, heating pads, and everything else you've tried aren't working. It sounds like time to try a specific massage for men to get those knots undone. In addition to a hair stylist, a dermatologist and primary care doctor are great resources if you have questions about hair or aging.
Facts That Will Change Everything You Think About Going Gray
As these stem cells divide, some become melanocytes and some stay as stem cells. This is a strategy for cells that are renewed all over our body. As we age, we run out of stem cells, so we don't make so many new specialized cells like melanocytes. Genes and diseases, like autoimmune diseases, can determine when and if you go gray. First, a little discussion on the anatomy of the hair follicle.

According to one study, low ferritin, calcium, and vitamin D-3 all affect graying, while another study concluded that low copper, zinc, and iron advance premature graying. Scientists believe they have discovered the mechanism for hair turning grey, which could help develop treatment to alter cells in order to reverse or halt the process. Stress may play a part, although don't go blaming your kid or significant other for your new silver strands quite yet. Stress can make your hair fall out, but if you're already going gray, the hair that grows back will be, well, gray. Common natural sources of vitamin B12 are dairy products and meat, which may explain why a vegetarian diet could be a factor in PHG.
Without pigment, new hair strands grow in lighter and take on various shades of gray, silver, and eventually white. Once a follicle stops making melanin, it won’t make colored strands again. Stress affects hormones, inflammation, and the behavior of melanocyte stem cells. Chronic stress eventually causes melanocyte stem cell failure, which results in irreversible hair color change. Chronic stress refers to an ongoing situation, such as a long illness, psychological stress, or permanent environmental stressor. Acute stress, such as emotional or physical trauma, may cause gray hair.

If some of your grays won’t take in the color, try using a lighter shade that will blend in with the grays. Historical accounts claim jailed British statesman Sir Thomas More and French queen Marie Antoinette went white overnight while awaiting execution. Some people start to go gray young – as early as their teens. When graying begins usually is determined by genes, so if your mother or father became gray early, you may, too.

It is better to have hair to color than hair that is thinning due to destroying the root by yanking it out,” says Marie Leppard, a senior colorist at Julien Farel Restore Salon & Spa in New York. Plus, plucking that gray hair isn't going to change anything. Yank out that gray hair and another one is just going to grow back in its place. Researchers continue to look for a way to reverse the graying process, but so far with little success. Some medications have been reported, in rare cases, to restore pigmentation in gray hair.
Why Does Some Hair Turn White Instead of Gray?
Instead, they get stuck within the hair follicle, incapable of either maturing into melanocytes or continuously proliferating as stem cells, the Nature study found. Melanocytes are generated by a small number of melanocyte stem cells within a niche in the hair follicle. Melanin in hair is produced by cells known as melanocytes, which inject the pigment into the shaft of each hair as it grows, according to the University of Alabama at Birmingham. These cells reside at the bases of hair follicles, the structures within the skin that grow hair. We’ve all heard the thought that stress causes gray hair, and in fact, recent studies suggest a link between the two. But, there are so many more reasons why your locks might be getting lighter.
Seeing Your First Grey Hair? Don’t Panic
Not Today, Grey is your secret weapon in the battle against oxidative stress turning your hair grey because it’s packed with antioxidants. Antioxidants are molecules that act like an off-switch to free radicals. I’ve spent about 36,000 hours talking about grey hair worries with my clients. Whether you choose to slow, delay, or cover up your greys, it’s a very personal decision. The good news is, thanks to advances in science, there are a lot of different options out there.
Hairs appear to the naked eye as white, silver or gray absent the pigments that otherwise provide color in shades of black, brown, blond or red. So, while it is inevitable that we will all lose our hair pigment one day, why do some of us go gray in our 20s, while some of us hold on to our colorful locks until our 50s? Research from 2016 showed that individuals with a certain variant of the gene interferon regulatory factor 4 are prone to earlier graying. Hair loss also can have other causes, including drugs or disease. For every person who embraces his or her gray hair, many more curse this very visible sign of aging. Overall, 74% of people between the ages of 45 and 65 years of age have at least a few silver strands, according to research from the National Institutes of Health.
Each hair follicle will eventually be unable to produce colored hair. The transition of hair color to gray or white depends on the loss of pigment produced by cells known as melanocytes, which are located in the hair follicles. As we age, the melanocytes gradually become less active and eventually stop producing pigment. When some pigment still remains, the hair appears gray as the dark or light pigments mix with the colorless hair. When there’s a complete loss of pigment, the hair appears white, which is simply hair without any melanin pigment.
Talk to your colorist about what's the best way to go gray gracefully, but don't stress out about it. It's known that some people with immune problems go gray. So they injected mice with capsaicin, the stuff in chili peppers, which is known to cause an immune stress response in mice. They did this in mice without immune cells, and the mice went gray. Seeing your hair turn shades of gray can be shooking, especially if you're not yet at the age when gray hair would normally start appearing. Why and how does hair turn gray, and why do some people "turn gray" earlier than others?
