This is a rumor and misunderstanding when people care for their hair.
It is wrong to pull out a long white hair. The truth of the matter is: if a hair can grow ten, how lucky it is! But every hair has a predetermined growth cycle (if a hair falls off, a new one will grow in place). If the white hair is pulled out, it will only shorten the life of this hair.
According to Professor Hou, a doctor in the family doctor's clinic of a local hospital, the hair follicles around the hair are actually formed during embryo formation. Although a hair follicle does not necessarily grow a hair correspondingly, the number of hairs is regular. According to statistics, there are about 6,543,800 hairs per person. With the increase of age, hair follicles will decrease, which is the reason why the hair of the elderly is scarce. Because the number of hairs is certain, the saying that "one hair has three long hairs" is not valid. Professor Hou also said that people often say that newborns will have thicker shaved heads, which is also unfounded from a scientific point of view.
There are two reasons why hair turns white: the first day and the day after tomorrow.
There are three reasons: insufficient nutrition, long-term mental stress and lack of sunshine. In addition, some skin diseases such as vitiligo can also lead to white hair. Normal people usually start to have white hair at the age of 35. If it appears early, you'd better go to treatment. According to Professor Hou, it is difficult to treat congenital gray hair, but acquired gray hair can be improved after treatment.
White hair refers to all or part of white hair, which can be divided into congenital and acquired Congenital white hair often has a family history, and localized white hair is more common, especially before hair. Acquired white hair includes senile white hair and juvenile white hair. Some old and frail young people with little white hair occur in children and adolescents, often with family history. Except for the increase of white hair, it does not affect their health. Young people suddenly have white hair, which is related to malnutrition. Mental factors can affect hair turning white. White hair can be a symptom of some diseases, such as Alzheimer's disease and vitiligo.
At present, there is no effective treatment for the disease, so patients should be helped to treat the disease correctly to avoid mental stress and depression. Hair dye is a common cosmetic for white-haired people, but it can cause hair dermatitis and should be used with caution.
Now, I am not afraid of long white hair, because I can dye it black, red and colorful.
However, soon after dyeing the hair, new hair grows out, ugly white hair "shuttles through it", and the whole head looks very indecent.
You can dye your hair again if you have money. You can pull out your white hair without money. However, white hair cannot be pulled out. When they grow taller in the spring breeze, some people can't help thinking, "It wasn't so tall before, but now it's getting longer and longer?"
Will white hair be pulled out more and more?
Dr. Chen Meie, a local Chinese medicine practitioner who supports his family, said that this is completely a traditional superstition. White hair won't grow more just because it's pulled out so little or a handful.
The growth of black hair is mainly formed by a cell called melanin in the hair root. It must be noted that the key to the left and right hair-colored melanocytes lies in the hair roots, so no matter how you pull out the white hair, it will have no effect on the hair roots and the white hair will not increase.
The biggest factor of white hair is the great pressure of life and too much pressure. When a person's stress exceeds his maximum limit, it will accelerate the turning of black hair into white.
Is white hair directly related to lack of nutrition?
She said that Singaporeans are generally not short of nutrition, mostly because of work pressure and mental stress, and the stomach can't effectively digest the food they eat, which leads to unbalanced nutrition, so white hair appears.
In addition, the lack of trace elements in the body is another reason for the formation of white hair. Eating underground tuberous roots can absorb a lot of trace elements from Polygonum Multiflori Radix, Radix Rehmanniae Preparata and even potatoes and taro, stimulate hair roots and grow black hair.
Just relax and don't put too much pressure on yourself in life. Even if you find one or two silvery whites on your head, you can safely pull them out, and your hair roots will still grow new black hair.
