It all starts from the roots.

There are melanocytes in the growth area of hair and hair follicle. Melanocytes can produce melanin.

in some cases, such as malnutrition, long-term mental stress, or due to some endocrine diseases, such as pituitary or thyroid diseases, pigment cells will reduce or even stop the secretion of melanin, making the newly grown hair shaft light or even white. Therefore, long white hair is the new root that grows white first.

Some may be due to the suspension of melanin secretion, which makes the white hair appear at the root, or it may be due to the fact that the first part is a piece of white hair, and then the function of pigment cells is restored, and the last part is a piece of black hair, which makes the white hair distributed at the tip, thus forming the illusion that the tip is white first.

Hair blackening generally starts from the hair roots. To blacken white hair, you can often eat foods rich in copper and iron, such as potatoes, spinach, tomatoes, persimmons, beans, black sesame seeds, walnut meat, sunflower seeds and animal livers. These foods are rich in pantothenic acid, which can accelerate the synthesis of black particles and promote hair follicles to grow black hair.

The occurrence of hoary head is mostly related to neurological factors, malnutrition, endocrine disorders and chronic wasting diseases.

Trace elements are closely related to hair color. In order to prevent premature appearance of baldness, we should pay attention to eating more foods containing iron and copper in our diet.

foods with high iron content include animal liver, eggs, auricularia auricula, kelp, soybean, sesame paste, etc. Foods containing more copper include animal liver, kidney, shrimps and crabs, hard fruits, dried apricots and dried beans. Pay attention to the intake of B vitamins.

By eating underground root tuber, how to absorb a lot of trace elements from it, such as Polygonum multiflorum Thunb, cooked sweet potato, potato and taro, stimulate hair roots and grow black hair. Extended information

Modern medicine believes that the occurrence of 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 deficiency of liver and kidney and deficiency of qi and blood. Congenital baldness is mostly related to heredity and difficult to treat; In addition to the treatment according to the etiology, the acquired baldness should also strengthen nutrition.

Experiments show that lack of protein and high malnutrition are one of the causes of premature gray hair. Lack of trace elements such as copper, cobalt and iron in 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 of black hair increases, the hair will turn gray. Golden hair contains titanium; Auburn hair contains molybdenum; Brown-red hair contains titanium as well as copper.

It can be seen that trace elements are closely related to hair color. In order to prevent premature occurrence of baldness, attention should be paid to eating more iron and copper foods in the diet.

foods with high iron content include animal liver, eggs, auricularia auricula, kelp, soybean, sesame paste, etc. Foods containing more copper include animal liver, kidney, shrimps and crabs, hard fruits, dried apricots and dried beans. Pay attention to the intake of B vitamins.

Medical scientists have now confirmed that the lack of vitamins B1, 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 liver, heart, kidney, milk, eggs and leafy vegetables. Also pay attention to eating more foods rich in tyrosine.

The process of melanin formation is that tyrosine is oxidized by tyrosinase. In other words, the basis of melanin formation is tyrosine, and tyrosine deficiency can also cause baldness. Therefore, we should eat more foods rich in tyrosine, such as chicken, lean beef, lean pork, rabbit meat, fish and hard fruit foods.

white hair

white hair refers to all or part of white hair, which can be divided into congenital and acquired. Congenital white hair often has a family history, especially local white hair, which is more common in the hairline in front of the head. Acquired white hair includes senile white hair and juvenile white hair. Some are old and weak with little white hair.

Adolescent gray hair mostly occurs in children and adolescents, and often has a family history. Except for the increase of gray hair, it does not affect the health. The sudden occurrence of white hair in youth is related to nutritional disorders. Generally speaking, there are several reasons in the day after tomorrow: lack of nutrition, long-term mental stress and lack of sunshine.

Chinese medicine believes that gray hair is caused by kidney yin deficiency, and weak renal function slows down the body's metabolic function. Therefore, the treatment of gray hair should first supplement kidney yin and fundamentally adjust the treatment. In addition, some skin diseases such as vitiligo can also cause white hair.

Normal people usually start to have gray hair at the age of 35. If they appear early, they'd better go for treatment. The white hair caused by congenital inheritance is difficult to treat, but the white hair caused by acquired causes can be improved after treatment.
