It's normal for hair color to change, as people age and grows older. Grey hair can appear at almost any time in life, even if you are young. Even teenagers and people in their 20s may notice strands of white hair.
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.
Gray hairs before the age of 30 are normal.
“It's not unusual to have a few gray hairs even if you're 18 or 20,” says Cotsarelis, noting that a gray hair occurs when the follicle stops producing melanin, the pigment that gives hair its color.
“Plucking a gray hair will only get you a new gray hair in its place because there is only one hair that is able to grow per follicle. Your surrounding hairs will not turn white until their own follicles' pigment cells die.” Dr.
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.
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.
There's a lot of misinformation about gaining back your natural hair color once it's started turning gray or white. While certain nutrient deficits and health conditions may spawn premature gray hairs, it's impossible to restore your natural hair color if your grays are genetic or due to natural aging.
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.
Alopecia and grey hair are associated with COVID-19 Severity.

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.
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.
And while it may seem intuitive that stress can accelerate graying, the researchers were surprised to discover that hair color can be restored when stress is eliminated, a finding that contrasts with a recent study in mice that suggested that stressed-induced gray hairs are permanent.
Drink six ounces of fresh amla juice every day or massage your hair with amla oil one time each week. Amla is also known as Indian gooseberry. Black sesame seeds (Sesamum indicum). Two to three times a week, eat a tablespoon of black sesame seeds to slow down and possibly reverse the graying process.
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.
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.
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.
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.
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.
So can gray or white hair turn black again? White or gray hair due to aging (old age) cannot turn black again naturally. In contrast, white hair appears due to bleaching, stress, food, pollution, vitamin deficiency, and other physical influence can turn black again if properly taken care of.
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.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and African-Americans in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
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.
Do not use harsh shampoos: The harsh chemicals in shampoos and conditioners are known to affect hair follicles, causing hair fall and greying. Shampoos contain several chemicals like hydrogen peroxide which can contribute to premature greying of hair.
