With the increasing social pressure, more and more people begin to have white hair, which also seriously affects people's personal image. However, in the face of the occurrence of white hair, few people correctly face the emergence of white hair, but take hair dyeing and other methods to deal with it. Here's why people have white hair.
Methods/steps
White hair is mainly divided into congenital white hair and acquired white hair. Congenital gray hair mainly has a family history, and localized gray hair is more common, especially the front hair. Acquired gray hair is juvenile gray hair, which is common in children and adolescents and often has a family history. Except for the increase of white hair, it does not affect health.
In congenital gray hair, if one or both parents have the gene of juvenile gray hair, it is likely to be passed on to the next generation of children.
There are three main aspects of acquired gray hair.
Poor nutritional status
Hair is an appendage of the skin. Like other organs and tissues in the body, it needs adequate nutrition. Because our hair pigment particles contain copper, cobalt and iron, they are brown and black. If the diet lacks inorganic salts such as copper, cobalt and iron for a long time, it will naturally affect the synthesis of melanin and make the hair turn from black to white.
Mental factors
If a person is depressed for a long time, in a bad mood or highly nervous and overworked, his hair can turn from black to white. For example, during the Spring and Autumn Period and the Warring States Period in China, Wu Zixu, a doctor of the State of Wu, suddenly became white-haired overnight in order to muddle through Zhaoguan. For example, Obama used to have black hair, but after he became president during the campaign, his hair changed from black to gray. It is not difficult to see that the generation of white hair is related to a person's mental factors and psychological pressure.
Disease factors
If a person suffers from wasting diseases such as pituitary hypofunction, hyperthyroidism, tuberculosis, typhoid fever, pernicious anemia and autonomic nerve dysfunction for a long time, it is also a disease in which hair turns from black to white.
How to reduce white hair? If white hair can be reduced slowly, this problem puzzles all white hair patients, so how to reduce it and what are the methods to reduce it? Let's have a look.
First, the diet is healthy and nutritious: the nutritional supply of hair that maintains normal pigments will also turn white. The gray hair caused by malnutrition, due to unbalanced diet, lack of certain vitamins and trace elements, melanocytes lost the function of producing melanin. It is necessary to supplement vitamins and trace elements in moderation. Eat more foods rich in vitamin B and foods rich in trace elements such as iron, copper, cobalt and iodine and high protein. Pay attention to diet adjustment and avoid partial eclipse. Often eat some nourishing food, such as walnuts, longan, sesame, fungus, black dates and so on. These foods contribute to hair growth.
Second, do more head massage: combing your hair frequently is also a physical massage method. The root cause of white hair is weakness and malnutrition. Therefore, there is a saying that "combing your hair is not white", which means that combing your hair often can prevent your hair from turning white.
Third, check the body to see if there are chronic diseases: some infectious diseases, such as dental caries, tonsillitis, suppurative sinusitis and so on. It can also cause white hair through bacterial action and nerve reflex. In endocrinology, pituitary gland, adrenal gland and autonomic nervous system are closely related to the secretion function of black excitatory hormone, which promotes the formation of melanin.
Fourth, mental relaxation: mental hoary head disease, characterized by rapid whitening of hair, due to extreme tension, sadness, fear, psychological disorders often cause a series of sharp changes in the body, so that the body's metabolism is disordered, and hair pigment can fall off in a few days to weeks.
5. Exercise: Any disease can't be treated without exercise, so we also know that another reason for long white hair is not exercising. It is suggested that you exercise properly, which can promote blood circulation throughout the body. Enhance the function of hair to make melanocytes.
