The relationship between the hair and the internal organs Chinese medicine believes that the kidney essence is abundant, hair lustrous, kidney energy deficiency, hair white and fall off. Because “the kidney is the master of bone marrow”, kidney essence is sufficient, the blood flourishes. The Five Organs of Suwen: “The kidneys are also the bones, and their hair is also the flower”, and Chinese medicine believes that “hair is the residue of blood”, “hair is the flower of the brain”, and “the lungs are also the skin, and its glory is the hair. The lung is also a part of the skin, and its hair is also glorified”. Hair health and kidney, liver, heart, lung, brain and other visceral tissues have a close connection. Hair black, lustrous, flexible, growth, signifies sufficient qi and blood, full of essence, brain health and prosperity. Without a healthy body hair beauty becomes a source of water, no wood. So our ancient medical doctors to health and hair care methods as one of the important setbacks to a long and healthy life. Modern medicine believes that the nutrition of hair is mainly fed by blood, hair is mainly composed of amino acids. The life span and color of hair is related to age, genetics and androgens. However, it is also determined by the health of the whole body, excessive anxiety, weakness and disease, the hair will become white and fall off. Certain diseases such as endocrine disorders, hyperthyroidism, severe anemia, vitiligo, malignant tumors, etc. can cause the hair to become yellow and white and fall out in patches. The importance of hair as a sign of health has been argued by both Chinese and Western medical science. The function of hair 1, hair has a protective effect on the head, and plays a cushion role against head injuries. 2, summer hair can withstand the sun, reduce the damage to the scalp and brain in the strong light of infrared and ultraviolet light, winter has a warm role. 3, hair is also a kind of excretory organs, can excrete water heat, detoxification if the human body has damage to the health of heavy metal elements such as arsenic, mercury, etc. can be excreted from the hair out of the body. 4, to determine the disease. We test the amount of zinc, copper, and other trace elements content in the hair to provide evidence for the diagnosis of disease. 5, identification of ethnicity to understand the living environment, according to the content of hair melanin can be judged as black, yellow, white. 6, the role of beauty, a dark and shiny hair, beautiful hair can often show a beautiful, dignified external temperament. The relationship between hair and emotional changes Chinese medicine believes that hair changes and mental emotions have a close relationship. Significant mental stimulation, excessive depression, thinking often cause premature graying of hair and hair loss. The “Thousand Gold Formula” says “early graying from worry”, and the “Essentials of Regeneration” says: “more anger and a hundred pulse uncertainty hair on the temples is pining”, too much thinking will be depleted of energy. It can be seen that the seven emotions can cause disease, can also lead to premature gray hair loss. Therefore, control emotions, avoid over-stimulation of the seven emotions, keep a cheerful mood, calm and optimistic good self-nurturing, regular life, can promote physical health, conducive to hair growth. Hair and aging Hair graying is a sign of aging, as the saying goes, “people get old from the head first, more white, less black”. From the hair, we can generally see the evolution of the kidney’s essence. According to the Nei Jing, at the age of eight, the essence of the kidney begins to fill up and the hair grows long. At the age of forty, the essence of the kidneys begins to decline, and the hair begins to fall out, and at the age of forty-eight, the hair is white at the temples. At the age of sixty, the essence of the kidney declines even more, the hair turns white, the body becomes heavy, and the walk is not correct. It can be seen that the essence of the kidney dominates the whole process of growth, development and aging of the human body. In general, the degree of aging can be inferred from the hair. However, there are also cases of white hair in youth and black sideburns in old age, which belong to the difference of endowment. Clinical significance of hair changes According to clinical observation, there are many causes of hair loss and different types. Physicochemical factors: strong acid, strong alkali have damage to the hair, try to less dyeing, less perm, do not use high-powered hair dryer blowing hair. Hair loss is aggravated when there is a temporary disorder of normal body functions or when you suffer from certain endocrine disorders. Such as hyperthyroidism, hypoadrenalism, chronic anemia, tuberculosis, diabetes, etc. Certain chemical drugs such as cyclophosphamide, nitrogen mustard, colchicine and other drugs can also cause chronic hair loss, hair gradually reduce, dry, easy to fall off. There are also many other factors that cause hair loss, such as baldness, seborrheic alopecia. Therefore, if you find hair loss, you must go to the hospital to find the cause of hair loss and diagnose it clearly so as not to delay the treatment. It can be seen that maintaining a healthy body is an important prerequisite for preventing skin and hair diseases and ensuring normal and perfect hair. Knowledge of hairdressing and hair care 1, to avoid evil aggression, pay attention to the daily cleaning of the hair, keep the hair clean, reduce the pollution of harmful substances, is the premise of normal hair growth. 2, to maintain adequate nutrition of the hair, hair is also alive, must be given adequate nutrition. The main component of hair is protein, protein accounts for 98% of the hair stem, so is often life should eat more protein-rich food. Such as milk, eggs, soybeans, walnuts, peanuts, sesame, etc. 3, diet should be moderate. Such as paste and thick taste, diet strong wine and tea, greasy food can lead to hair malnutrition and abnormal. 4, prohibit poor-quality chemical shampoo and hair dye. Poor-quality chemical shampoos and hair dyes can damage hair hair, long-term use of toxic substances into the body to destroy the hematopoietic system, causing significant damage to our bodies. Carcinogens can easily enter the capillaries along the scalp and enter the bone marrow with the blood circulation, which will destroy the hematopoietic stem cells and cause leukemia in the long run. Chinese medicine believes that the head is the meeting of all the yang, the bottom of the clear yang, thought the brain sea is located. Where the essence of the five organs of the fluids, the six bowels of the essence of Yang, are injected into the head, so the hair is moist or scorched, soft and smooth with the internal flow of Qi and blood, the function of the viscera have a close relationship. Therefore, hair care is to maintain health.
