How does white hair come about? Li Kai, Yang Dingquan, Bai Yanping Editor Bao Jun's gray hair is a physiological phenomenon when he is old. Traditional Chinese medicine believes that white hair after 40 years old belongs to natural aging white hair, before 20 years old, it is youthful white hair, and middle-aged white hair is in between. Hair is the crown of capacity, and young people's white hair gives people a feeling of aging before they get old, which is easy to feel inferior and worry. With the development of society, people's pace of life is accelerating, work pressure is increasing, and at the same time, they are highly nervous. Coupled with lack of sleep and other reasons, there are more and more young people with white hair. So, how does white hair come about? Is it possible for white hair to turn black? Are there any measures to prevent white hair? Is dietotherapy effective for white hair? Please look down. What are the related factors of baldness? Adolescent gray hair is mainly related to genetic factors, mental factors, nutritional disorders and suffering from some chronic diseases. At present, it is believed that the pathogenesis of gray hair is mainly due to the decrease of tyrosinase activity and melanin synthesis in hair balls, which leads to the gradual whitening of hair. In addition, the migration of melanocytes from the outer hair root sheath to the hair follicle is reduced, which will also destroy the normal coloring function of hair. Too little intake of protein, severe malnutrition and lack of trace elements can also lead to hair turning white. Experiments show that if black mice keep eating foods lacking folic acid, pantothenic acid, vitamin B 1, vitamin B2 and vitamin B6, their hair will turn white. The color of hair pigment particles is often related to the metal contained. Pigment particles in black hair mainly contain elements such as copper, cobalt and iron. If these elements are lacking, or these elements cannot be transported to the hair roots normally, the hair will turn white. Studies have shown that among people with family history of adolescent white hair, the possibility of adolescent white hair is about 6 times that of people without family history. In addition, some chronic diseases, such as autonomic nervous dysfunction, hyperthyroidism, pernicious anemia, tuberculosis, cardiovascular diseases, autoimmune diseases, long-term chronic wasting diseases, endocrine dysfunction and so on. It can also lead to white hair. Is it possible for white hair to turn black? You can delay the increase or blackening of white hair through reasonable diet, regular life and relaxation. Clinically, we can often observe three phenomena of white hair turning black. 1. Tumor patients lose hair after chemotherapy, and some regenerated white hair will turn black. 2. When patients with severe alopecia areata are in remission, the white villi can gradually turn black and eventually return to normal black hair. 3. After the improvement of blood supply to the head of patients with cerebrovascular disease, the white hair of some patients improved obviously. However, once the blackened hair is stopped, it is possible to slowly return to the original white hair state. The exact mechanism of blackening is still unclear and needs further study. Why does the pressure of work grow white hair? Mental factor is an important factor of modern people's early gray hair. Mental stress, sadness, anxiety and panic caused by heavy work pressure are all causes of gray hair. According to modern medicine, unhealthy mental factors will cause vasospasm that supplies hair nutrition, hinder the function of pigment cells in hair and hair bulb to secrete melanin, and affect the formation and transportation of melanin particles. A certain degree of psychological pressure makes the body in a state of tension, which leads to serious and lasting neuroendocrine disorder, increased catecholamine secretion in the body, contraction of peripheral blood vessels, and microcirculation disorder. Norepinephrine in catecholamine can strengthen the synthesis of melatonin, leading to an increase in white hair. Does premature graying of hair mean physical injury? "On Etiology and Staging of White Hair" said: "Deficiency of qi and blood, weakness of kidney qi; If the kidney is weak, the bone marrow will fail, so the hair will turn white. " The kidney dominates the bone to produce marrow and store sperm, and its flowers are in the hair; The liver stores blood and sends it with blood; Spleen governs blood and transport. Young people's liver qi is vigorous, blood heat is excessive, and it is easy to consume yin blood, such as emotional fatigue, excessive anxiety, fatigue and heartbreak of the spleen, or mental exhaustion and liver qi discomfort, which leads to passive biochemistry of qi and blood, qi stagnation and blood stasis, long-term deficiency of essence and blood, and insufficient metaplasia of yin and blood, which eventually leads to hair loss and whitening. In short, Chinese medicine believes that premature graying of hair is closely related to kidney, liver and spleen, and the health of hair cannot be separated from the nourishment of qi and blood. If qi and blood can't shine on the head, it will lead to white hair. Therefore, white hair also reflects a person's visceral dysfunction or deficiency of qi and blood nutrition to a certain extent.
