Why white hair

First: white hair is mainly divided into congenital white hair and acquired white hair, congenital white hair is often a family history, with limited white hair more common, more common in the anterior hairline. Acquired white hair is juvenile white hair, juvenile white hair occurs in children and adolescents, often with a family history, in addition to the increase in white hair, does not affect health. In congenital white hair, if either or both parents have the gene for too little white head, it is likely that it will be passed on to the child in the next generation.

Second: there are three main aspects in the afternature of white hair. Poor nutrition, hair is the appendage of the skin, it is the same as other parts of the body organs, tissues, need adequate nutrition, because our hair pigment particles contain copper, cobalt, iron, so it is brown black, if the diet in the long-term lack of copper, cobalt, iron these inorganic salts, will naturally affect the synthesis of melanin, make the hair from black to white.

Third: mental factors if a person is depressed for a long time, in a bad mood or in a high degree of mental tension, overwork, can make the hair from black to white. For example, during the spring and Autumn period and the Warring States period, Wu Zixu, a doctor of the state of Wu, turned grey all over his head overnight in order to get through Zhaoguan. For example, Obama originally had black hair, but after he became president during the election campaign, his hair turned 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.

matters needing attention

1、 Diet health nutrition: hair loss to maintain normal pigment nutrition supply will also become white. Due to the imbalance of diet, lack of some vitamins and trace elements, the melanin cells lose the function of producing melanin. It is necessary to supplement vitamins and trace elements appropriately. Eat foods rich in vitamin B and foods rich in iron, copper, cobalt, iodine and other trace elements and high protein. Pay attention to diet regulation, avoid partial diet. Often eat some nourishing food, such as walnut, longan, sesame, fungus, black jujube, etc., these foods help the growth of hair. Second, do more head massage: frequent combing is also a physical massage, the root of white hair is weakness, malnutrition, so there is a "thousands of comb, hair is not white" idea, which means frequent combing can prevent hair from becoming white. 3. Check your body to see if you have chronic diseases: some infectious diseases, such as dental caries, tonsillitis, suppurative sinusitis, can also cause white hair through bacterial action and nerve reflex. In the aspect of endocrine, pituitary gland, adrenal gland and autonomic nervous system are closely related to the secretory function of black stimulating hormone which promotes the formation of melanin.
