Hello, host, audience and friends! This is the live program of the road to health. Welcome to watch and participate in our program. When we open the newspaper every day, we will see two kinds of advertisements, one is beauty advertisement and the other is hair loss advertisement. In fact, many hair loss advertising industries have explained a problem. Many people are facing such troubles. What causes people to lose their hair? What good method is there to treat alopecia? Today, we invited experts to tell us that the two experts who came to the studio today were Zhang Jianzhong, director of Peking University People's Hospital, and Cai Lin, deputy chief physician.

Moderator: There are two experts' colleagues in today's program. If you have any questions, please contact us. Before today's program began, we learned about the current situation of hair loss through a reporter's investigation.

You must be familiar with such a picture. In recent years, you must have added many such friends around you. In April, 2005, China organized a health education activity on male hairline defense system, aiming at guiding men with hair to receive formal treatment. Hair loss has therefore become a topic of concern to everyone.

At present, domestic experts are becoming younger, and this aspect is developing. According to the data given to us by some experts, at present, they found that the earliest male hair loss was 18 or 17 years old.

Nowadays, hair loss is no longer a patent for the elderly. Facing the problem of hair loss, what attitude will young men with hair loss have? In order to solve this problem, China Medical College conducted a survey on men with hair loss under 50 years old in Beijing, Shanghai, Shenzhen, Guangzhou and Hangzhou.

Experts point out that only about 50% of all men with hair loss realize that it is a disease. Only 10% of these 50% people will go to the hospital to consult a doctor. And then go to treatment. In other words, only 5% of male patients with alopecia go to the hospital.

The Chinese Medical Doctor Association hopes to improve the knowledge and understanding of male hair loss diseases in China, cultivate their formal awareness of treatment and further improve their quality of life through the health education activities of male hairline defense system.

The host learned two questions from this survey. The age trend of first-time hair loss is getting lower and lower. People don't realize that he is a disease, so how many people are actually suffering from it?

Cai Lin has five big cities in China, and has made a survey in this field. It is found that the proportion of hair loss in people aged 20-30 is about 10%. With the increase of age, this proportion is gradually increasing. It is found that the average proportion of people with hair loss at the age of 20-50 in China is about 25%. Of course, it looks terrible. I am gratified that we are much lower than the white people in Europe and America, because half of them will lose their hair around the age of 50.

The host talked about the problem of hair loss. My own feeling is that hair loss is actually normal, and combing my hair can happen at any time every day?

Zhang Jianzhong We healthy people each have about 654.38+ million hairs, and each hair has life, which is a life cycle. We need to know how much it is normal to lose weight every day and how much it is abnormal. Let's take a look at how long hair is. This is the growth cycle of hair. Generally speaking, it starts from the growth period. Generally speaking, our hair will grow for 2-6 years, and we will rest for a while, sometimes for about three months. Then on this road, it will have a three-week transition period. You can see that long-term hair follicles are very strong and big.

Moderator: Rich in nutrition.

Male expert: It begins to shrink when retiring, and becomes a small gland when resting, which is very thin. Hair tends to fall off at this time. It is normal for a person to have about 50 to 100 hairs. It is not normal to exceed this. These 50 to 100 hairs are a foundation.

Moderator: Just now, your circular chart told everyone the life span of hair. The reflection hair seems to be a combination of young and old, and it is also vital, which is also a demographic feature.

Male expert: Well, it's actually microscopic.

Moderator: Small world. Just now, you asked a question. Hair loss of more than 50 to 100 hairs may be some dangerous signals, which is abnormal. So apart from some quantitative changes, what other characteristics indicate abnormal hair loss?

Female expert: As Professor Chang Si just assumed, you obviously started to lose more than 50 to 100 hairs. Everyone thinks that if you lose too much, the shape of your hair will change, because if you lose too much, it will be too late to grow, just like a tree being cut down. Everyone feels the same way. As long as the mountain is bare, there will be less forest on the hair, that's all. This pattern has changed.

Moderator: judging from the shape of this hair, it also suggests that we have abnormal hair loss. What changes have been made?

Male expert: Generally speaking, male hair loss is mainly on the top of the head and forehead, and the pillow, back of the head and both sides are generally normal. We usually see two kinds, one is headless, and we call this bright scalp the Mediterranean. Because the Mediterranean is surrounded by land, and he is an ocean, this man has just appeared in the Mediterranean. If it is more serious, his whole scalp will fall off. There is hair around, but there is no hair in the middle. It is the Mediterranean Sea. The other is not from the top of the head, but from the forehead hairline. Look at the two sides of this person's forehead, forming an M-shaped expression, so we call it M-shaped alopecia. Whether he is mainly on the top of his head or on his forehead, his mechanism is the same, including male hair loss. Of course, the worst time is when the whole head is stripped off, that is, combing your hair every day to see how much hair you have lost, and combing your hair every day to see if the problem has changed.

Moderator: When the hair has a big retreat above our heads, the truth will change at this time.

die

Commentary: In the last two years, 35-year-old Mr. Zhang has always encountered such a thing.

At the same time, Mr. Zhang: I had dinner with some new friends, and then because we didn't know each other well, we tried to figure out each other's ages, and then asked me politely, how old are you? I asked how old you were, and I said I was younger than all of you. Oh, they just have that look. It seems a little unexpected. It's a little hard to watch in my heart.

Commentary: Are you really that old? A haircut soon after, let Mr. Zhang find the reason at once.

At the same time, Mr. Zhang: When I went to the barber's for a haircut, the barber told me that your hair was quite rare, and then she took a mirror behind me and took a picture of me. At this time, I found that there was very little hair in my position, especially this one.

Commentary: Looking at his naked scalp in the mirror, Mr. Zhang's mood suddenly fell to the bottom.

Teacher Zhang breathes: It seems that I used to feel that my age is increasing bit by bit, but I don't think other physical changes have special reminders for myself, but it is this hair loss that makes me feel as if I have suddenly gone from this stage of my life to that stage of my life.

Commentary: Because of hair loss, Mr. Shao, 36, didn't want to face our camera, but he still told his troubles on the phone.

At the same time, Mr. Shao: I began to lose my hair at the age of 27 or 28, and now I can see the scalp on my head. In other words, in the Mediterranean, colleagues and leaders in the company should have a healthy image, so hair loss may affect the performance of this healthy image of the company. In this case, I feel that it is more difficult for me to work and be promoted than other colleagues.

Commentary: Hair loss has brought a lot of trouble to Mr. Shao's work. For the same reason, he also had trouble finding a girlfriend.

At the same time, Mr. Shao: I am thirty-six, and I am not married. I once had a girlfriend who was dishonest because she lost her hair. Nowadays, girls may be interested in image.

Commentary: What do female friends think of this problem?

Female 1: I think imagination is a problem.

Woman 2: From the appearance, I think it's ugly.

Woman 3: I think if I am bald, I will get old.

Woman 2: At least it may be a little repulsive at first.

Woman 4: Think about the future, because it's prenatal and postnatal care now. Think about your children.

Woman 5: The whole person's mental state will not be very good.

Woman 6: I don't think it matters.

Woman 7: This is not the only criterion. Mainly depends on whether two people are in harmony.

Woman 8: Maybe this is good, so I won't care about his appearance.

Woman 9: People don't say that smart people have hair on their heads. Smart people may lose their hair easily.

Commentary: From our investigation, we can see that although hair loss has brought troubles to men, the attitude of society towards men with hair loss has become more and more tolerant.

Moderator: Through the telephone interview with Mr. Shao just now, we learned that it is difficult to make friends for promotion because of hair loss. There is always an unwritten rule when looking for a job. People over 35 don't think much about this. It seems that they handed in a letter of recommendation saying that I am 35 years old. It is out of the question. People put a question mark. In fact, after listening to the conversations of several female pedestrians, I really don't have to pay too much attention.

Female expert: Generally speaking, this kind of hair loss is just an image problem, not a disease of your body, but an obstacle when we are marching on the road of pursuing beauty after the improvement of our living standards, so everyone doesn't pay special attention to his meaning, but it may have a certain impact on your promotion and making friends, because many of our clinical patients are mothers with sons. My son may be in his twenties. He came up and said, doctor, you give me a good look. My son is only in his twenties, just graduated from college and has no girlfriend. He just graduated from graduate school and hasn't found a job yet. You must make him look younger. There are indeed doubts or concerns in this regard.

Moderator: But Dr. Cai said one thing. First, this is a question about appearance and beauty, not about health, and has little to do with his own health.

Male expert: This hair loss is mainly an image problem, but the image problem depends on you. Some people say that attitude determines everything. Some people are obsessed with hair loss and have problems finding friends and jobs. But some people don't think so, it doesn't matter, some people are kind. For example, I have a friend with mild hair loss. I said that you now have a new drug for treating male alopecia. Do you want some? He said I don't want it.

Moderator: I think it's hard for Professor Zhang to meet this kind of professor Zhang to buy medicine, and it's hard to boast, but it's hard to talk about it when he is rejected for the first time, but I think it's still the same sentence, smart heads don't grow hair.

Female expert: It is true that I have done some observation and statistics in clinic and often ask patients what you do. It is often said that I am engaged in computers, accounting, and some mental workers who use more brains, which may indeed conform to the statement that smart brains are hairless.

Moderator: Actually, the hair loss man thinks about it now. Although I lost my beauty score, I got other scores in professional education, social respect and so on.

Male expert: So we must have a healthy attitude.

Moderator: Don't take it too seriously. It won't harm our health. Just now, Teacher Zhang said that it suddenly feels that from this age stage to another age stage, we have a word called middle age, but it may give Teacher Zhang a feeling that he has lost all his hair and is over middle age. So, Mr. Zhang, what is the reason for his hair loss? Let's take a look.

die

Commentary: I am young, why did my hair fall so badly? Mr. Zhang suspects that it was three years ago. Three years ago, Mr. Zhang bought a big house with his savings loan for many years, and the next step was decoration. During that time, Mr. Zhang was busy with his work every day, and he had to rush around the major building materials markets after work. The choice of materials and decoration workers repeatedly discuss the needs of decoration. Mr. Zhang is a perfectionist. He wants to give his wife and son a warm and comfortable home. Busy for two months, the house is decorated, but Mr. Zhang's hair is getting less and less.

At the same time, Mr. Zhang: I just got up and saw a lot of hair on the pillow towel. Then when I combed my hair, I found a lot of itchy hair in the seam of the comb. I lost my hair when I scratched my head. I think this seems normal. People lose some hair every day.

Commentary: whoever doesn't lose dozens of hairs a day, Mr. Zhang didn't take it seriously until he was reminded by the barber in the barber shop. Now that his hair is falling so badly, Mr. Zhang believes that it must be related to his original decoration of the house.

Moderator: You see the reason why Teacher Zhang found himself. Suspicion may have something to do with buying a house and decorating the house under high pressure. Some netizens call it Crystal. He asked whether hair loss was related to heredity. Everyone is looking for relevant reasons, but what is the real inducing group?

Female expert: heredity is the most fundamental reason. Heredity can be said that there are many reasons for hair loss, but the genetic background is the most fundamental. It is found that heredity accounts for 90% of the reasons, and almost 90% of patients have genetic background.

Moderator: If the father is the first generation to listen to light bulbs and the son is the second generation to listen to light bulbs?

Female expert: or even if he is not, his grandson may be the second generation of light bulb.

Moderator: Indirect inheritance

Female expert: There is no indirectness, that is to say, it may not be obvious in the son, but it may be revealed in the grandson.

Moderator: That is, heredity is the main factor, so what other factors besides heredity?

Female expert: As Teacher Zhang said, his suspicion is right, and mental factors have a lot to do with it. Many patients ask me that although my father took off his hair, he didn't take it off until he was 40. Why did I take it off in my twenties? I didn't take it off until I was 40. I answered him that this kind of question is very common. Your father didn't develop so fast in the fifties and sixties. At that time, your work pressure, study pressure and making friends pressure were not so heavy. You are under a lot of pressure at work and life now. This has a lot to do with mental factors.

Moderator: I may prove this myself. At the age of 25, I was under great pressure for a while, and suddenly I lost my hair locally and suffered from short baldness. But once time was too tight and the pressure was great, I suddenly lost my hair locally and suffered from alopecia areata.

Male expert: alopecia areata is also related to mental stress.

Moderator: the second point is mental and neurological factors, stress, the second male hair loss,

Male expert: People nowadays have a very fast pace and great pressure. What should they do if they can't finish it? They worked until midnight.

Moderator: Strike

Male expert: If you can't strike, you will lose your job. Of course, you have enough fun until 2: 00 or 3: 00, when you play more than 2: 00. If this goes on for a long time, the biological clock will be disrupted and the schedule of work and rest will be disrupted. The affected autonomic nerves are in a state of balance. It disturbs this point and also promotes hair loss.

Moderator: It's just that the biological clock is out of order.

Male expert: the disorder of biological clock affects the balance of autonomic nerves and can also promote hair loss.

Compere: Actually, understand the influence of biological clock on hair. Can you understand it this way? I don't rest when I should rest, and my hair is tired.

Male expert: That's right. You should rest and leave him alone. Many diseases are not only hair loss, but also related to the disruption of the biological clock.

Moderator: The Black Forest also needs to sleep. What if there is something wrong with endocrine?

Female expert: Endocrine is related to genetic background, and we have also studied the causes of male hair loss. That is to say, the level of androgen in his hair, including his body, is relatively high.

Moderator: I followed the trail and found the real answer, didn't I? In addition to the genetics, endocrine, mental factors and autonomic nerves we just saw, androgens actually run through them.

Male expert: Male alopecia is medically called androgenetic alopecia.

Moderator: Androgenic alopecia

Male expert: the high level of chest hormone is his essence. There is a very interesting example. We used to have eunuchs in China, and eunuchs were all castrated. Two eunuchs didn't get sick for long. One disease is that they don't have sores, and the second is that they don't have male hair loss. This proves that chest hormones play a very important role in thorn sores and male alopecia.

Moderator: With historical and scientific proof, let's talk about how this rooster element made this black forest slowly disappear and wither.

Male expert: Androgen has some male signs for people, men and the maintenance of sexual function, such as backstreet and beard. So what does he show in his hair? Generally speaking, the androgen on the top of the head is high, and the mammary gland hormone acts on the hair follicle, which can make the hair follicle shrink and contract slowly, so the long-term hair preservation period is originally two to six years, which can be shortened. The resting hair band is only 65,438+00%, which can be increased to 25%, an increase of more than 40%. There are too many hairs with small follicles in this resting period, and it is easy to fall off, and if it is not treated, it will gradually become healthy, from hypertrophy to atrophy.

Moderator: The withered hair follicle has changed from a big tree to a small tree, from a small tree to a sapling, and finally to a grass and disappeared. In fact, seeing this androgen act on this hair is just like acting on the soil environment.

Male expert: Well,

Moderator: Just like saline-alkali land.

Male expert: When he is strong, this hair is like a big tree or a strong crop, so it is shrinking and getting smaller and weaker. Watering him at this time can save him. But if the seedlings are too dry, they will die, or they will soon become saline-alkali land.

Moderator: Under the action of androgen, our scalp may become saline-alkali land, and our hair may not grow. Then find out the real reason is androgen. What kind of medical treatment should we take for this effect of androgen?

Female expert: As Professor Zhang said just now, androgen has a certain influence on hair growth, from vigorous hair roots to atrophy. This hair shaft is from coarse to fine. If we want to break this balance, we will not continue to reverse it. Now let's look at a picture, on the next page of * * * *;
