Modern medicine believes that baldness is mostly related to neurological factors, malnutrition, endocrine disorders and chronic wasting diseases.

Traditional Chinese medicine believes that this disease is mainly caused by liver and kidney deficiency and qi and blood loss. Congenital baldness is mostly related to heredity and difficult to treat; Acquired alopecia should be treated according to the etiology, and nutrition should be strengthened. Experiments show that protein deficiency and high malnutrition are one of the reasons for premature gray hair. Lack of trace elements such as copper, cobalt and iron in the diet can also cause hair to turn white.

In recent years, scientists have found that pigment particles in hair contain a mixture of copper and iron. When the nickel content in black hair increases, the hair will turn gray. Golden hair contains titanium; Auburn hair contains molybdenum; Brown-red hair contains titanium in addition to copper. It can be seen that trace elements are closely related to the color of hair. In order to prevent premature baldness, we should pay attention to eating more iron and copper foods in our diet. Iron-rich foods include animal liver, eggs, black fungus, kelp, soybeans, sesame paste and so on. Foods containing more copper include animal liver, kidney, shrimp and crab, hard fruit, dried apricots and dried beans. Pay attention to the intake of B vitamins. Medical scientists have now confirmed that the lack of vitamins B 1, B2 and B6 is also an important cause of baldness. The intake of such foods should be increased, such as cereals, beans, dried fruits, animal livers, hearts, kidneys, milk, eggs and leafy vegetables. Also pay attention to eat more foods rich in tyrosine. The formation of melanin is formed by tyrosinase oxidizing tyrosine. In other words, the basis of melanin formation is tyrosine, and tyrosine deficiency can also lead to baldness. Therefore, we should eat more foods rich in tyrosine, such as chicken, lean beef, lean pork, rabbit meat, fish, hard fruit and so on.

In addition, often eat some foods that are conducive to hair care and blackening, and increase the raw materials for synthesizing melanin. Traditional Chinese medicine believes that "hair is blood" and "kidney dominates bone, and bone slides in hair", and advocates eating more foods that nourish blood and kidney to moisten hair and blacken hair.
