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.
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.
A deficiency of vitamin B12 in the body is most likely result in the greying of hair in children. Stress and an extra load of exams or studies in children may also result in premature greying.
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.
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.
Expert answer. A strand of hair can appear gray when it contains a decreased amount of a pigment called melanin, and it can look white if there is no pigment at all. Gray hair occurs with normal aging because the hair cells on the scalp produce less melanin; in children, early graying tends to be inherited.
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.
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.”
Although this may seem like a permanent change, new research reveals that the graying process can be undone—at least temporarily. Hints that gray hairs could spontaneously regain color have existed as isolated case studies within the scientific literature for decades.
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. As people continue to get older, fewer pigment cells will be around to produce melanin.
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.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, medications, your gray hair cannot be reversed.
Premature graying of a person's hair is largely connected to genetics as well. Race and ethnicity play roles, as well. Premature graying in white people can start as early as 20 years old, while a person can be as young as 25 years old among Asians, and 30 years in African-Americans populations.
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.
The team ultimately discovered that signaling from the sympathetic nervous system plays a critical role in stress-induced graying. Sympathetic nerves extend into each hair follicle and release noradrenaline in response to stress. Normally, the melanocyte stem cells in the follicle are dormant until a new hair is grown.
Alopecia and grey hair are associated with COVID-19 Severity.
Hair lightening
According to these articles, the citric acid in lemon juice is a natural bleach, or oxidizing agent. It whitens hair by chemically reducing your hair's color pigment, or melanin. When exposed to the sun, the citric acid accelerates the bleaching process.
It can be due to a dirty scalp, dandruff, infections like fungal infection of the scalp, e.t.c. It can be due to chemicals like hydrogen peroxide present in hair colors, which have a bleaching effect. Deficiency of nutrients like vitamin B. complex, copper, iron and iodine is known to cause premature graying.
Vitamin A, C and B12 are the most needed vitamins to increase the melanin production in your hair. Add citrus fruits like oranges, grapes, pineapple, and melon to your diet. Also eat vegetables like potatoes, carrots, beans, etc. Non vegetarians can try adding red meat, chicken liver, fish, and eggs to their diet.
“Gray hair tends to turn a dull yellowish color that can age you, so try keeping it shiny and bright.” You can do this by using toning, purple-colored shampoos. Popular options include Aveda's Blue Malva Shampoo, Davines Alchemic Silver series, and Joico's Color Endure Violet.
