Introduction

Introduction to white hair Whites are white hairs that are all or part of the hair white. Less whiteheads: congenital whiteheads, the most common people with such whiteheads often have a family history, often have white hair at birth, or hair is whiter than others, in addition, no other abnormal performance; acquired whiteheads There are many reasons for this: malnutrition, such as lack of protein, vitamins and certain trace elements (such as copper), will make the hair white; some chronic wasting diseases such as tuberculosis, due to lack of nutrition, hair is also better than the average person It should be whiter earlier; some patients with long-term fever, hair will be yellow and brittle or even white off; some endocrine diseases, such as pituitary or thyroid disorders, can affect the ability of pigment cells to produce pigment particles and cause hair to prematurely white Some young people have a lot of white hair in a short period of time, which is related to severe trauma or mental fatigue caused by excessive anxiety and sadness. Symptoms: When adolescents or young people develop symptoms, the first few hairs are sparsely scattered in the hair. Most of them first appear in the back or top of the scalp. They are white in the black hair. Then, the white hair can gradually or suddenly increase. , sudden occurrence, related to nutritional disorders. Senile white hair: Its white hair often starts from the two corners and develops chronically to the top of the head. After a few years, the beard and nose hair are also grayish, but the chest hair, pubic hair and mane are not white even in old age. The tyrosinase activity in melanocytes is progressively lost to cause the pigment in the hair shaft to disappear. The number of melanocytes in gray hair is normal, but melanin is reduced, and melanocytes are also reduced in white hair. Symptoms: Two white hairs appear, and white hair on the head appears one after another. basic knowledge Probability ratio: Susceptible people: more than teenagers Mode of infection: non-infectious Complications: autism

Cause

White cause

Genetic (25%):

Early gray hair or white in the elderly has a family history, manifested as autosomal dominant inheritance, also found in certain syndromes, such as progeria, Rothrnund syndrome and Werner syndrome, Waardenbur syndrome, muscle Dystrophic myotonia (dystrophia myotonia).

Disease factors (15%):

Severe diseases such as pernicious anemia, hyperthyroidism, cardiovascular diseases such as coronary heart disease, myocardial infarction, peripheral arterial disease, hypertension, tuberculosis, typhoid, syphilis, etc. may occur with white hair.

Physiological phenomenon (25%):

Gray or whitening of the aged hair is a physiological phenomenon caused by the progressive loss of tyrosinase activity in melanocytes, which causes the pigment in the hair shaft to disappear. The number of melanocytes in the gray hair is normal, but the melanin is reduced. The melanocytes in the white hair are also reduced.

Decreased tyrosinase activity (20%):

White hair is caused by the production of melanin due to melanocytes, less melanosome or decreased tyrosinase activity.

Prevention

White hair prevention

1. Stay optimistic

Being optimistic about life and maintaining a happy mood will help to make your hair black and white. Even if you encounter unsatisfactory things or even misfortunes, don't let your psychological world fall into desperation. Because this is not to blame yourself for taking the mistakes of others, it will not only help, but will also be counterproductive, and even cause greater misfortune, thus speeding up the pace of white hair.

2, strengthen nutrition

The loss of nutrients in the hair that maintains normal pigmentation will also turn white. Many scientific studies have proved that niacin, amino benzoic acid, carotene and citric acid in vitamins have an important influence on the formation of pigments and their metabolism. If they encounter obstacles or changes in absorption, storage, utilization, etc., the blue silk can become hoarfrost. In the recipe, foods containing vitamins B1, B2, B6, niacin, etc. should never be lacking for a long time. Otherwise, the hair will turn gray from black and whiten. Scientific research in recent years has also shown. The lack of certain trace elements, such as copper, iron, etc., can also make the hair white. Therefore, in order to prevent and control the whiteheads, we should pay attention to starting from the diet, usually eat more vitamin-rich beans, vegetables, fruits, miscellaneous grains, in order to fully absorb the nutrients that produce black hair. The liver of various animals contains more copper. Tomatoes, potatoes and spinach also contain a certain amount of trace elements such as copper and iron, which should be eaten properly. Of course, people who suffer from white hair due to lack of vitamins can also take vitamin B2, B6 and multivitamins, but they can't be seen immediately. They need to be taken for a long time under the guidance of a doctor.

3. Treating diseases

Certain infectious diseases and chronic local focal inflammation. Such as dental caries, tonsillitis, suppurative sinusitis, etc., through bacterial action and nerve reflex, can also cause white hair. In the endocrine aspect, the pituitary gland, adrenal gland, and autonomic nervous system are all closely related to the secretion function of the black excitatory hormone that secretes melanin. Normal endocrine, secreted black excitatory hormones, the formation of more melanin, hair color is darker; on the contrary, white hair will grow. In addition, sexual function can also cause white hair. Therefore, in order to prevent long-haired hair, it is necessary to treat the above diseases as soon as possible.

4, massage the scalp

In order to prevent white hair, you can insist on drawing a small circle on the scalp with your index finger and middle finger after getting up in the morning and before going to sleep, and licking the scalp: first from the front of the forehead to the back of the occiput, then from the forehead through the temples on both sides to the pillow unit. Each massage for 1 to 2 minutes, 30 to 40 times per minute, and gradually increased to 5 to 10 minutes. This massage can accelerate the blood circulation of the hair follicle and make the nipple get a sufficient blood supply. Thus, the pigment cell nutrition of the hair bulb is improved, the cell activity is enhanced, and the division is accelerated, which will help to secrete melanin and darken the hair.

5, diligently combing hair

The hair comb is also a physical massage method, which is from the hands of the surrogate medical family Chao Yuanfang. In the "Sources of Diseases" and "White Hair", he believes that the root cause of white hair is weak body and malnutrition, so there is the idea of "severing a hair brush, not white", which means that hair combing can prevent hair from changing. White. This is very scientific: diligently combing the hair, not only can keep the scalp and hair clean, but also accelerate blood circulation, increase the nutrition of the pores, and thus achieve the effect of preventing whitening of the hair.

Examine

White hair check

Mainly for the primary disease selection auxiliary examination. Blood routine (blood image) examination: Blood routine examination is one of the most basic laboratory tests in the clinic. Blood tests include red blood cells, white blood cells, hemoglobin, and platelet counts. The blood routinely collects the finger blood or the peripheral blood of the earlobe by acupuncture. After dilution, it is dropped into a special calculation disk, and then the number of blood cells is calculated under a microscope. Common symbols on blood routine tests are: RBC stands for red blood cells, WBC stands for white blood cells, Hb stands for hemoglobin (hemoglobin), and PLT stands for platelets.

Diagnosis

White hair diagnosis

diagnosis

Modern medicine believes that white hair is mainly caused by decreased hair melanin formation, weakened melanin production by melanocytes, and reduced tyrosinase activity. Excessive emotional stress, excessive brain use, anxiety, panic, and nerve trauma may cause white hair. In addition, white hair may also appear in chronic consumptive diseases.

Differential diagnosis

Congenital whiteheads: The most common people with such whiteheads often have a family history, often having white hair at birth, or hair being whiter than others. In addition, there are no other abnormalities.
