Whether the gray hair will be pulled out more and more is a topic that has rushed to the hot search list. This makes the editor a little inexplicably surprised, this has little to do with the upcoming National Day holiday, and it is not like a major event such as power rationing in various places that will attract the attention of all parties, how did it suddenly become a topic that everyone is concerned about? #深度好文计划#
Pluck gray hair
However, since everyone is very interested in this, and this is also a matter closely related to many netizens, young white netizens may be worried about the impact of white hair on their appearance, and older netizens may be concerned about white hair affecting the display of spirit. Therefore, the editor hurriedly and carefully did his homework, sorted out the ins and outs of this matter, and did not seek to be able to completely answer questions, but to be able to give you some information for reference.
What determines the color of the hair
In fact, pulling out white hair is not to let others see that you have white hair, after all, as a Chinese person, a black and bright black hair is an important symbol of us, and gray hair will involuntarily associate aging to a certain extent.
Brilliant hair
So let's first understand what exactly determines the color of hair and see if we can solve the problem fundamentally. Hair color is determined by melanocytes, where the two different forms and amounts of melanin contained in the cells directly determine what color our hair is. According to scientific research, the main influences on hair color are eumelanin and pheomelanin. Eumelanin is a biological pigment that is more commonly found in people with black hair and dark hair.
Melanocytes
Pheomelanin is also a biological pigment that is more commonly found in blonde and red-haired people. Therefore, the eumelanin in our hair is dominant, making the vast majority of Chinese people's hair color appear black. However, melanin is not found in the hair bulb cells at the base of the hair, but is distributed above the hair follicles. When hair grows, melanin is transferred along the protrusions of the hair cells to the cells that come into contact with it, giving the hair its color.

In addition to the main melanocytes, scientists have also found that trace elements contained in hair tissue can also have a certain effect on hair color. Among them, trace elements zinc, iron, and copper are very important elements for hair.
Why the older you get, the more gray hair you have
Usually as we get older, we find that we have grown gray hair. So why is this happening? Because as you get older, your body's metabolism will gradually slow down, and your body's various functions will slow down. As a result, the ability to break down catalase in the body is reduced, resulting in a large accumulation of hydrogen peroxide in the hair. Hydrogen peroxide can affect our hair color by destroying the pigment cells and melanocytes in the scalp.
catalase
As melanocytes are destroyed, the amount of melanin transferred to contact cells is also greatly reduced. At the same time, melanocytes also have their own growth cycle, and after several growth cycles, they will gradually age, and it is difficult for aging melanocytes to release melanin, and without the output of melanin, the hair will also turn white. Therefore, as we get older, the aging of the body is an irreversible process, and we will find more and more gray hairs.
Why some people have fewer whiteheads
At this point, some people will ask questions, and we will often see young people with gray hair, what is going on?
Less whiteheads
This is commonly known as "less whiteheads", and the reasons for less whiteheads are also varied, the most common of which comes from genetic inheritance. Scientists have found that interferon regulator 4 (IRF4) in the gene plays a role in the graying of hair color. This is because the IRF4 gene is directly involved in the production and storage of melanin, which in turn directly determines hair color. As a result, scientists have now identified IRF4 as the gray hair gene. When IRF4 is present in the family gene, the offspring are more likely to have fewer whiteheads.
Genetics
There is also an important reason due to excessive stress. Excessive stress will cause oxidative damage to the body, and the so-called oxidative damage is not only a specific injury to a certain part of the body, but a comprehensive damage to the body, including melanin, which affects the color of the hair, which will make the hair turn gray prematurely.
Antioxidant
Of course, the imbalance of nutrient intake will also lead to the phenomenon of less whiteheads, and in the case of lack of nutrients, melanocytes will also not have enough nutrients to release melanin to supply the hair.
Will gray hair get more and more pulled?
Many people will have this experience when they are young, that is, helping some elders who have just grown gray hair to pluck gray hair. At the same time, the phrase "pull one and grow ten" is inexplicably imprinted in our little brain. According to scientific research, each hair has its own growth cycle, and hair follicles will grow new hair in about 2-4 months after the hair falls naturally or passively. The act of pulling out the hair is a human intervention that shortens the normal growth cycle of the hair itself.
Contrast of hair follicles in black and white hair
Different people have different numbers of hair follicles, and each person has their own quantitative number of hair follicles, so pulling out gray hair is hair and does not affect the hair follicles, so in essence, plucking gray hair does not increase more and more. However, because the process of pulling hair will more or less damage the hair follicles and scalp, some will affect the healthy growth of hair, resulting in hair loss, and even folliculitis in severe cases.
Inflammation of hair follicles
Of course, the gray hair will not be pulled out less and less, and the hair that grows under the hair follicle that pulls out the gray hair is not necessarily black, if it is not changed from the whole, the hair that grows under the hair follicle is likely to be white.
How to recuperate to avoid growing less gray hair
Pulling out gray hair alone cannot solve the root problem, and a balanced intake of the nutrients needed by the human body will bring a healthy growth environment for our melanocytes, which can essentially improve the state of gray hair. Moreover, it is necessary to focus on supplementing healthy ingredients containing trace elements such as zinc, iron and copper.
Eat a balanced diet
For example, proper scalp massage will help promote blood circulation and allow blood to be transported to all corners of the scalp, thereby helping melanocytes function normally; When the head is exposed to ultraviolet rays for a long time, it is necessary to pay attention to sun protection, physical sun protection is particularly important, umbrella and hat are good choices, so as to protect melanocytes from damage; Adequate sleep is also essential, the body is a kind of self-repair and regulation when sleeping, and the same is true for melanocytes, which are exposed to ultraviolet rays during the day, and can focus on the production of melanin that is not affected by the outside when sleeping.
Sun protection
Finally, the relaxation and happiness of the mood will also directly affect the state of our hair, when we are in a state of tension and instability, it is easy to make the body's own nervous dysfunction, so the function of secreting melanin is also different, when the human body is extremely nervous and sad, it will cause serious endocrine disorders, and some people will even have a white head overnight. Therefore, for the health of our hair, it is especially important to relax our minds.
epilogue
In general, gray hair does not pluck more and more, but in the process of plucking, it will have a great negative impact on our hair, scalp, and hair follicles. Although it is only a gray hair, it is more than worth the loss for the overall hair health.
Gray hair
If you want to have black and shiny hair, you need to start from the inside of your body and try to live a healthy life. The so-called healthy life is all aspects of life, diet, mood, sleep, exercise, protection. If it's really because of age, please accept the change in hair color, different colors have different beauty, and don't pull out gray hair again.
