Genetic or disease factors
The appearance of white hair has a certain relationship with heredity. People who have gray hair or white hair before they are old often have a family history, which is autosomal dominant inheritance, and can also be seen in some syndromes (such as presenile syndrome and comprehensive myotonic dystrophy). In addition, suffering from some serious diseases, such as pernicious anemia, hyperthyroidism, cardiovascular diseases, tuberculosis, typhoid fever, syphilis, etc., can also lead to gray hair.
For this kind of people, we can improve the whitening of hair by insisting on massaging the scalp. The specific method is: before going to bed and after getting up in the morning, insert your hands and fingers into your hair and rub your scalp from the forehead to the back of your head for 2-4 minutes each time. It can improve scalp nutrition, regulate sebum secretion, promote scalp blood circulation and enhance local metabolism.
Lack of trace elements such as copper and iron
Studies have shown that the lack of protein and high malnutrition are one of the causes of premature gray hair, especially the lack of trace elements such as copper, cobalt and iron in the diet can also lead to gray hair. In recent years, scientists have found that the pigment particles in hair contain a mixture of copper and iron. When the nickel content in hair increases, it will turn gray. Therefore, trace elements are closely related to the color of hair.
In order to prevent baldness, we should pay attention to eating more foods containing iron and copper in our diet. Iron-rich foods include animal liver, eggs, auricularia auricula, kelp, soybean, sesame paste, etc. Foods containing more copper include animal liver, kidney, shrimps and crabs, nuts and dried apricots.
Lack of B vitamins
Medical research has found that the lack of vitamin Bl, vitamin B2 and vitamin B6 is also an important cause of baldness. You should eat more foods rich in B vitamins, such as cereals, beans, animal hearts, livers and kidneys, milk, eggs and green leafy vegetables. Traditional Chinese medicine believes that hair is blood, and the kidney dominates the bone, and its flower is in the hair. It advocates eating more foods that nourish blood and tonify the kidney to moisten the hair with black hair.
Work or life is stressful.
Modern people are under great pressure in work and life, prone to mental stress, emotional depression, long-term lack of sleep and excessive thinking, which leads to liver and kidney deficiency, qi and blood deficiency and premature gray hair.
Therefore, we should learn to decompress ourselves, face life with optimism every day, and eliminate mental fatigue through simple exercises such as deep breathing, walking and relaxation gymnastics. Soaking feet with warm water after work every day also has obvious effect on decompression.
In addition, we should pay attention to maintaining a balanced nutrition and eat less spicy, greasy, fried and other foods; Avoid eating too much sugar, oil, salt, etc.
