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.
As you age, the amount of melanin in your hair naturally declines, which causes your hair to appear gray and eventually white. Along with the hair on your head, your eyebrows and eyelashes can turn gray or white with age. The graying process often starts with a few hairs before spreading.
The cure for such a case is to include more and more vitamin B12-rich food in their diet. Applying castor oil or olive oil to the eyebrows can also help to prevent premature loss of pigments from the hair. Not to mention, it also helps to boost the hair growth to provide you a more defined eyebrow.
It can be a shock to find your first gray hairs on your head, especially if you're only in your 20s. But women's expert Dr. Kirtly Parker Jones says a few gray hairs is perfectly normal, even for women in their late 20s and early 30s. However, stress, genetics and other factors can play a role.
Eyebrows are somewhat of a mystery. They frame our eyes and give character to our faces. But, as we age, they have a tendency to become a little “higgledy-piggledy.” They also turn grey with time, sometimes on a completely different schedule than the rest of our hair!
Though, ageing is the primary reason of grey hair but premature greying of hair in early 20's or 30's is now common. Genetic factors, stress, lack of nutrition, chemicals, smoking or any underlying disease like anemia can also lead to premature greying of hair.
Genetics
If you notice white hair at an early age, it's likely that your parents or grandparents also had graying or white hair at an early age. You can't change genetics. But if you don't like the way your gray hair looks, you can always color your hair.
Poliosis is a patch of white or gray hair on your scalp, eyelashes, or other parts of your body. It can occur at birth or can appear suddenly at any age. Poliosis itself isn't harmful, but it may be triggered by some medical conditions like thyroid disorders and vitamin B12 deficiency.
Greying of hair is a hereditary condition that is passed on from the parents to the children. This is not an indicator of health. It just means that the hair is grey, that's it! So if your toddler has only one gray hair or even a few more, don't worry.
Poliosis, also called poliosis circumscripta, occurs when you have a white streak in your hair, contrary to your natural hair color. This can affect hair on any part of your body, including your eyebrows and eyelashes, as well as the surrounding skin.
Gray hair occurs with normal aging because the hair cells on the scalp produce less melanin; in children, early graying tends to be inherited. A single strand of gray hair is most noticeable in people with darker hair and is usually not worrisome if the child's general health is normal.
The graying of hair in older adults is a natural process. But premature graying of hair in children is not. Although the reason might be genetic in some children, it might also be associated with a health condition such as vitiligo or neurofibromatosis.
Can White Hair Turn Black Again? Genetic or age related greying of hair cannot be reversed. However, greying related to diet, pollution, bleaching and stress can be slowed down with a balanced diet and a good hair care regimen. Know your hair to figure out hair care that suits your hair.
Kraleti doesn't recommend plucking or pulling the hairs out. “If there is a gray hair you must get rid of, very carefully cut it off. Plucking can traumatize the hair follicle, and repeated trauma to any follicle can cause infection, scar formation or possibly lead to bald patches.”
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.
Some people develop their first strands of gray or white hair in their 30s or 40s, whereas others develop white strands in their 20s or teenage years.
Genetics
The most common cause of premature greying of hair in children is genetics. Simply put, if the parents or grandparents had a similar problem of premature greying of hair in their childhood, the children will also be at a higher risk of this condition.
Genetics: It's all in genetics, say doctors. According to studies, premature greying happens due to genetics. Talk to your parents or even grandparents on when they first spotted their grey hair. If they had it very early in their age, chances are there you too will do the same.
It is normal for hair color to change, as people age. But white hair can appear at almost any time in life. Even teenagers and people in their 20s may notice strands of white hair. The human body has millions of hair follicles or small sacs lining the skin.
It can be perfectly normal for children to have a gray hair every now and then. However, as you mention, a dietary deficiency may sometimes be to blame.
People can get gray hair at any age. Some people go gray at a young age — as early as when they are in high school or college — whereas others may be in their 30s or 40s before they see that first gray hair.
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).
Blue hair does not naturally occur in human hair pigmentation, although the hair of some animals (such as dog coats) is described as blue. Some humans are born with bluish-black hair (also known as "blue black" hair), which is black that has a blue hue under the light.
Gray hair grows when hydrogen peroxide builds up in your hair follicle. "This causes hair to bleach itself from the inside out," says Debra Jaliman, MD, a dermatologist in New York and spokesperson for the American Academy of Dermatology. Gray hairs are thicker and wirier, so your hair gets coarser as they multiply.
