It is said in the book that there are fewer whiteheads because acidic items are eaten more

I remember when I was in junior high school chemistry, generally speaking, the chemical formula of a substance containing H+ is acidic, such as H2SO4;

A substance is alkaline if it contains oh- in its chemical formula. For example, Na(OH)2;

Of course, you can't force that as long as the chemical formula contains H, it is considered acidic, because this H is likely to belong to some atomic group, and it is connected to other chemical elements by covalent bonds, and it is impossible to be acidic. This acid is not the kind of acid of vinegar but a chemical property.

Less whiteheads, known in Western medicine as presenile whitehead, is a kind of white-haired disease in childhood and youth, which is very complex, with two major types, one is congenital less whiteheads, and the other is acquired less whiteheads. Many of the acquired whiteheads are accompanied by certain diseases, and some are caused by excessive stress and malnutrition. Traditional Chinese medicine believes that hair is closely related to vitality, zongqi and camp qi, and the supply or functional status of the three can be dynamically balanced in order to make the human body's hair normal and beautiful, if there is a deficiency of qi, it will affect the operation or function of other qi; If the two qi are damaged, it will inevitably cause damage to the human body and hair, lose its normal structure and nature, and manifest itself as different degrees of pathology.

There are many diseases that can be associated with the appearance of progeriatric gray hair, such as pernicious anemia, hyperthyroidism, cardiovascular disease (myocardial infarction, atrioventricular bundle block, hypertension, etc.), dystrophic myotia, vitiligo, and voggett Koyanagi syndrome. In addition, changes in the body's mental state, such as long-term depression, excessive anxiety or emotional stress, and panic often cause the hair to turn gray rapidly. The above-mentioned diseases, as well as nutritional and spiritual factors, will cause the balance of vitality, sect qi, and camp qi to lose balance, resulting in damage to the hair, which is what we often call "hurting the vitality".

This kind of premature gray hair does not need to be special**, just find**and**it**.

As for congenital progeria, most of the white diseases are caused by heredity, such as hereditary progeria, Bucco's syndrome, and Wordenberg's syndrome, which often have a history of inheritance in the family for several generations, and hereditary defects and albinism are also congenital genetic diseases. Except for acquired abnormalities that are acquired local** and most of them can return to normal after months and years, these progeria leukopathies** are caused by inherited genetic mutations that cause the body's tyrosine metabolic pathway to be completely (such as albinism) or locally blocked.

Children and young people should go to the hospital for examination as soon as possible, and after the diagnosis of their onset, as long as they are ****, they can be cured.

Traditional Chinese medicine believes that the premature appearance of gray hair in adolescents is often caused by sorrow and worry, blood and heat, and hair loss. It is advisable to treat cool serum fever, nourish the liver and kidneys, and choose Wanshou Dizhi Pill and Wufa Pill to be cut. 150g of medicinal raw and cooked ground, 100g of angelica, 80g of angelica, 200g of mulberry, 200g of ligustrum, 200g of lotus grass.

Finely ground together, honey refined into pills, 10g per pill, 3 times a day, 1 pill each time.

Malnutrition is an important cause of less whiteheads, because these teenagers do not pay attention to the intake of nutrients, such as vitamin B, folic acid, pantothenic acid, etc., and their hair will turn gray. Our daily foods, such as pork liver, beef liver, meat, eggs, tomatoes, vegetables, rice bran, etc., are rich in B vitamins, and eating more of these things is good for the growth of hair pigment. Neuropsychiatric factors will also increase gray hair in the short term, as the saying goes, a sorrowful and gray head.

Excessive nervousness, anxiety and severe mental trauma, as well as severe headaches and scalp neuralgia can cause nervous dysfunction in the body, cause hair dystrophy, and cause gray hair.

The occurrence of less whitehead is related to hereditary and constitutional factors.

Congenital hypoplaxia. People who most commonly have this type of whitehead often have a family history of having gray hair at birth, or having gray hair earlier than others. In addition, there were no other abnormalities.

Acquired less whiteheads. There are many causes of this: malnutrition, such as lack of protein, vitamins and certain trace elements (such as copper), can make hair gray; Some chronic wasting diseases, such as tuberculosis, cause nutritional deficiencies, and hair is grayer than the average person's; Some patients with long-term fever will have yellow and brittle hair or even turn white and fall out; Some endocrine diseases, such as pituitary gland or thyroid disorders, can affect the ability of pigment cells to produce pigment granules, resulting in premature graying of hair. Encephalitis, nervous system lesions, etc. can also turn hair gray; The **, hair, and eyebrows of the person with albinism are all white; **Whitening disease - "vitiligo", if it occurs on the scalp, the hair will also turn white; Others believe that the more you use your brain, the sooner your hair will turn gray; Some young people have a large amount of gray hair in a short period of time, which is related to severe mental trauma such as excessive anxiety, sadness or mental fatigue.

Many reasons, genetics, stress, staying up late, etc. My family has hereditary gray hair, but I have always been in good health, and I thought that gray hair would not happen to me. I didn't expect everything to come so suddenly, half of my gray hair was in 3 years, and a large patch of hair on the top of my head was thinned.

I have also tried some methods during this period of gray hair loss, such as ginger, black sesame seeds, etc., but there are no results I want, so I have a desperate feeling about my hair, so I start to let it go. But during this period, not only did the weight soar, but the hair oil also increased, but fortunately, my friend later told me the knowledge in "Weng Lin's Dense Hair Road", and I followed it, and now the gray hair and hair loss are gone, and I feel that the whole person is confident.

The article said: usually eat more vegetables and fruits with high vitamin content, spinach, black fungus, walnuts, kelp, carrots, beans; Usually you can exercise more, enhance your physique, play less with mobile phones, computers and other electronic devices, and at the same time pay attention to ensure a good mood, don't let yourself worry too much, and have a good attitude; Try not to scatter: the weather is too hot in summer, if you always loose hair, the hair is also easy to get greasy, because the hair is easy to get wet with sweat, wet hair is also more likely to stick to dust, and it is easy to get oily when the hair is dirty, so it is best to tie the hair.

Mental factors.

If a person is depressed for a long time, has a poor mood or is highly stressed, and overworked, it can turn hair from black to white. Maintaining a positive and optimistic attitude towards life and having a good mental state are the most critical factors in preventing and reducing whiteheads.

Nutritional status. Hair is the appendage of the first body, and it needs adequate nutrition like the organs and tissues of other parts of the body. According to medical clinical observations, if the body lacks protein, vegetable oil, vitamin B1, vitamin B2, and vitamin B6 for a long time, it will also cause the hair to turn from black to white.

Diseases, Drugs, and Genetics.

Diseases, drugs and genetics are also factors that cause hair to turn from black to white, endocrine disorders such as decreased pituitary gland function and hyperthyroidism, wasting diseases such as tuberculosis, typhoid fever, pernicious anemia, and autonomic dysfunction have all been found to be related to hair from black to white.

Gray hair is caused by a decrease in the amount of melanin that forms hair. It may be hereditary, or it may be overused for a long time.

Heredity, nutrition, stress. Yes, it mainly depends on what causes you, if you are genetic, you can accept this fact, and the nutritious Hua will eat more black beans, black sesame, shou wu and other black hair foods, and the pressure will reduce the pressure on yourself.

Less whiteheads are more blood fever, kidney qi weakness, qi and blood weakness are the causes of gray hair, the method of traditional Chinese medicine is mostly to replenish liver and blood, tonify kidney qi, this situation is generally slow to recover, it is recommended to find Chinese medicine syndrome differentiation **conditioning. Eat more black sesame foods and carefully choose shampoo to care for your hair, and it will gradually improve.

Hair can be yellow, brittle or even gray and fall out, as can be seen in some endocrine diseases, such as pituitary gland or thyroid disease.

Recommendation: Fewer whiteheads can be caused by a variety of factors. For example, genetic, nutritional, mental factors, etc., please first determine the cause of the lack of whiteheads, and then deal with it in a targeted manner.

Maintain an optimistic and cheerful mood. Pay attention to exercise, combine work and rest. Eat more foods that contain vitamins B, 1, B2, B6 and copper, iron and other trace elements.

Rub your scalp often with your fingers. You can also use a comb to comb your scalp every day, which can also have the same effect as massaging your scalp.

If gray hair is caused by other diseases, the related diseases should be actively treated.

Because vegetables and fruits contain potassium, sodium, calcium, magnesium and other salts, they are metabolized in the human body to produce alkaline substances, making body fluids weakly alkaline. This type of food is physiologically called alkaline food.

2. The citric acid and its potassium salt in lemon are thoroughly oxidized in the body, and the citric acid is finally excreted into carbon dioxide and water, leaving alkaline potassium salt. Therefore, this type of acidic food is alkaline food. Although she tastes sour, which is felt by our own sense of taste, but chemically it is alkaline, can you understand this?
