How humans lose their hair, let’s have a look

Hello everyone, I am a hair loss editor of Aunt Zhang's

Let's talk todayAnti-hair loss and hair growth products, drugs and hair transplantThose things

A handful of hair drops, the head is sparse, and the hairline is behind...... It seems that the issue of "hair loss" is no longer the patent of the middle-aged and the elderly. It is presented to friends of all ages in various forms.
Don't say anything else, emotional work pressure, the pressure of buying a house and a car, the pressure of children entering a higher school...... How can you not have more hair on your morning comb?

No one wants to be the bald one before getting old. Everyone has tried every means to save their hair-what can be saved? What can be saved? Even...... Which is better, hair transplant or wig?

The editor will come to talk with you this time. What is the root of your hair loss? And, which hair growth method is suitable for your hair loss degree?
●Grade and cause of alopecia
●Anti-detachment and hair growth medicineOverview
●Side effects of drug therapy, as well as crazy release period and relapse

●Introduction to technology and process of hair transplant
●Suitable population for hair transplant, charging situation and organization selection

First, what level has your hair loss reached?


Hair loss grade, in fact, has been written a lot everywhere, the editor also posted two pictures here, please refer ~
For male alopecia, Hamilton classification is often used 」. Male hair loss is mainly reflected in the backward movement of the hairline or hair loss starting from the head.

●First-level alopecia, no obvious alopecia phenomenon, normal hairline. It mainly depends on adjusting work and rest, supplementing nutrition or moderate exercise.
●Secondary alopecia, male forehead angle hairline back about 1~2cm. You can start taking some oral or external drugs.
●Three-level alopecia, hairline obviously moved backward. If it is not treated in time, it will fall off quickly and seriously. It is recommended to go to the hospital for examination.
The above is the initial stage of alopecia. In the early stage of hair loss, you should pay attention to one thing,Hairline backward movement is not a symptom of alopecia, but a symptom of alopecia.. For CET-4 and above, you don't need to be persuaded by the editor to prevent it early, but everyone can see that you have hair loss and need treatment

For female alopecia, the Ludwing classification method is often used 」. The hair loss of women is mainly manifested in the sparse overhead of the coronary area. When changing from Type I to Type II, girls should begin to pay attention! Actively seek treatment, do not delay ~

The editor is probably type I

II. Which type of hair loss do you belong?


As the saying goes, "the forehead that is not bald is always similar, and the types of hair loss are different".
There are four common types of Alopecia:
●Male hair loss
●Round hair loss
●Female hair loss
●Rest period alopecia
Generally speaking, bald and Mediterranean are the first two. The editor will introduce these types of alopecia respectively. Friends with alopecia can take their seats

2.1 male hair loss
Male Alopecia is the most common type of alopecia. If you find that the hairline moves backward gradually, and the hairline of both sides moves backward at the same time, and the hairline of both sides moves backward at a faster speed, with M-shaped expansion on the forehead, you may need to highly doubt whether you are "male hair loss.
In addition to the M-shaped hair loss, some people begin to lose hair from the top of their heads, which is commonly known as Xie Ding. This is also a common type of male alopecia.

Look around you, colleagues, relatives and friends...... There is always a male hair loss......


2.2 round hair loss
Round hair loss is also called alopecia areata, and folk is also called "ghost shaving head". Think about it, one morning you get up to take photosMirror, I found a piece of hair suddenly missing, the hair loss part is round, the boundary is particularly smooth, it seems that someone shaved the hair secretly.
Round alopecia is related to immunity disorder. In addition, mental stress can also cause round alopecia.

2.3 female hair loss
I have talked about male hair loss before, now let's talk about female hair loss. In general, the situation that the hairline of the female hair loss moves backward is relatively slight, and most of them are the scalp in the middle hair Division area becoming more and more obvious.

2.4 alopecia during rest period
Hair drop is a normal physiological phenomenon. Normal people drop 50~100 hairs on big dates every day, and a corresponding number of new hairs will be added every day, and the overall hair volume remains unchanged. However, if the hair drops over 100 within a period of time, and the newborn hair is not enough to fill the vacancy of falling off, it will be "serious hair loss. This kind of hair loss is called "resting period hair loss" in medicine 」.
In general, severe hair loss is common in these populations:
●Too fast weight loss
●Maternal
●Sudden pressure (such as illness, divorce, unemployment, etc.)
●High fever
●Rehabilitation after surgery or serious illness
●Stop taking contraceptives (yes, you are right)

More commonly, new mothers may start a large number of hair loss two months after delivery, usually the most serious hair loss four months after delivery. Since the hormone level of postpartum women will fluctuate sharply and then gradually return to normal, this kind of hair loss is only temporary. Generally, within one year after delivery, the new mother's hair will return to the prenatal level.
"Resting period alopecia" for patients, generally after a period of time, the hair will return to the original level.


III. Overview of anti-detachment and hair growth drugs


The editor once wrote an article about anti-detachment products, so I won't go into details here.


This article mainly talks about anti-detachment drugs. Generally speaking, judging whether a product is effective mainly depends on two points: scientific verification and public praise. As the matter of word of mouth is indeed quite different from people's point of view, too much talk is also a suspicion of soft articles, so I will not mention more here, mainly talking about drugs that have been scientifically verified.
For the certification of anti-detachment drugs, the right of comparisonAuthorityThe agency is FDA. FDA is the abbreviation of the U.S. Food and Drug Administration. It is an international medical audit authority, authorized by the U.S. Congress, and the highest law enforcement agency specializing in food and drug management. In general, food and drugs certified by FDA are recognized as safe and effective.


3.1 FDA certified drugs: minoxidil, finasteride

There are two kinds of drugs certified by FDA to treat alopecia: minoxidil and finasteride.
Minoxidil is a non-prescription drug, which is mainly used for hair growth and can be purchased in general pharmacies. Finasteride is used to inhibit hair loss, which belongs to prescription drugs and can only be purchased after a doctor's prescription.
Interestingly, minoxidil was used to treat hypertension at the beginning, and finasteride was used to treat prostate diseases at the beginning, but in the process of use, it was found that the hair of patients who took the medicine grew rapidly, so the sideline became the main business

Some time ago, when the editor was anxious about hair loss, his best friend recommended a product to him. Let's not talk about the brand. A treasure searched and found it was minoxidil.

3.1.1 minoxidil
Minorandil's hair growth principle is to increase the nutrition and blood supply of scalp and promote hair growth. Although minorandil's additional effect is relatively weak, it is very safe and cost-effective. It only costs about 100 yuan a month.
It is generally recommended that men use 5% minoxidil. If the hair loss area is large, spray type is recommended; If you are very careful, it is better to choose drip type.
If you select the drip type, you can use half tube for the first time, that is, 0.5cc, and gradually increase the usage later.Note that it must be applied to the scalp, not to the hair!Men should pay attention to that both sides of the hair are the key smearing areas.
Women can also use minoxidil, but the concentration cannot exceed 5%, otherwise it may make you grow a beard (the probability is about 3%). Many 3A hospitals in Beijing recommend that women use 2% Minoxidil for treatment first.
The common domestic brands of minoxidil include Mandy, sbishen, dachexin and so on, and the imported brands include Luojian and Kelan and so on.

The editor searched the prices respectively. Domestic minorandil often has some discounts, including the discounts. The average price ranges from 80 to 100, and the average price of imported minorandil is 120 +.
In fact, there is not much difference between the two stimulating hair growth effects, which can both achieve the effects of increasing proliferation and differentiation of hair follicle epithelial cells, promoting blood circulation and increasing local blood flow.
However, imported dianjian foam package without propylene glycol may be a little more expensive than ordinary solution. Compared with ordinary solution, foam package will be more refreshing when used (can be compared with bubbleHair dyeAnd ordinaryHair dyeAgent).
Minorandil is a product that has been used for a long time. Although the unit price difference between imported products and domestic products is only a few dozen yuan, in the long run, this price difference is also a big expense. You can do it according to the situation.


3.1.2 finasteride
As mentioned earlier, the main cause of male alopecia is androgen. Androgen will become dihydrotestosterone after metabolism in vivo, abbreviated as DHT. After the binding of dihydrotestosterone and the receptor of hair follicles, the living environment of hair follicles will be harsh, resulting in alopecia.
Androgen conversion to DHT requires two enzymes, called reductase I and reductase II. While finasteride is fighting against reductase II, making androgen combine with drug instead of reductase II, thus DHT cannot be synthesized.
Clinically, the effective rate of finasteride is 70%-90%, but the effective rate only refers to the effect produced by the drug, which achieves remarkable effect to improve the appearance of alopecia, and the probability is 40%-60%.
Attention!!! Finasteride is a major hidden danger to women's pregnancy and childbirth, and is ineffective for postmenopausal women. It is not recommended for women to use any finasteride drugs.

Regarding minoxidil and finasteride, it is generally recommended to use them in combination. Some research institutions have compared the two drugs:
●Minoradil alone: the effective rate is 64.7%, and the effect is produced in 3 months
●Using finasteride alone: the effective rate is 75%, and the effect is obtained in 130 days
●Minorandil + finasteride: Effective rate 85.7%,2-month effect

3.2 Other word-of-mouth products
For other drugs that have not been certified by FDA, on the one hand, the safety and effect cannot be guaranteed; On the other hand, there are some non-medical problems (commerce, patents, etc.) in the approval of drugs. Even if these drugs are not approved, there are still a small number of users. Most of these people have a certain Medical Foundation and can recognize the risks and benefits.
3.2.1 Degree taxiamine
Then we will talk about the small science popularization about DHT. Dutaxiamine can combine with reductase I and reductase II at the same time in the fight against reductase, and its efficacy is undoubtedly stronger than finasteride,But the lethality is too strong, and the side effects are also greater than finasteride.
In 2001, taxiong Amine was approved by FDA to treat benign prostatic hyperplasia, but it was not approved to be used for alopecia. The American medical community believes that there may be unpredictable risks in taxiong amine.
Moreover, 90% of male alopecia is due to reductase II, and finasteride has a long history of use and has a large number of clinical data, so it is generally more likely to choose finasteride.
If it is M-type male alopecia with backward hairline, androgen can combine with reductase I and reductase II together, so we can also choose ditaxiamine, or dutaxiong amine and Finasteride are used crosswise, for example: use finasteride 4-5 times a week, and use dutaxiong Amine 1-2 times in the middle (the specific usage method must follow the doctor's advice).
3.2.2 Natural plant saw Palm
The natural plant saw Palm is another medicine for the treatment of alopecia, which has the title of "plant finasteride", but the clinical verification of its effect is very few. There is a view that saw Palm has only 1/10 finasteride effect, so although its side effects are very small, it is not enough to replace finasteride.

Four, the side effects of drug therapy, and crazy degassing, relapse



4.1 side effects
Friends who have some knowledge of anti-detachment drugs may have heard such a saying:

According to the information on the Internet, the use of finasteride and dotaxiong will reduce sexual desire and lead to a decrease in Ejaculation volume.

Low.

This situation does exist, but clinical data show that the proportion is not high, about 2%. For more information, see the experimental results.

(Clinical and Experimental Medicine) journal published 201 cases of male alopecia in April 2008

Factor analysis and treatment experience of feinazong glue). Take feinazong 1mg orally, and take at least 4 consecutive doses

In January, 201 people participated in 72 patients who insisted on taking drugs for more than 3 months, accounting for 36%. Fenasong glue

In the group of 72 patients taking medicine for more than 3 months, 56 patients feel effective, the effective rate accounts for 77.8%, see

The effective time is about 3 months. In terms of adverse reactions, about 2% of people's sexual function is affected and drug withdrawal

The latter 2 weeks subsided.

There are a lot of literature on finasteride and its side effects, and the editor lists several important points here:
●The probability of side effects of finasteride is generally not higher than 3%, and the probability of serious side effects is not higher than 1%. Permanent side effects are rarely recorded and can fade 2 weeks after drug withdrawal.
●Most people will feel uncomfortable after taking finasteride, the proportion can be as high as 60%, but these feelings will gradually fade after gradually taking drugs.

●Finasteride usually takes effect for more than 3 months. Most people cannot stick to this time, and only less than 40% of people can stick to it for 3 months.
That is to say, most people will have discomfort when using it at the beginning, but the actual side effects are less than 3% (the side effects you feel may only be discomfort + Psychological effects) in addition, most people only experience discomfort, but do not insist on generating profits

Of course, if there is obvious discomfort, you can discuss with the doctor to adjust the dose. If you are really worried about side effects, you can make oneSpermDetection, mainly observe sperm quality (sperm density, active sperm density, etc.), and make a comparison after taking the medicine. In addition, it can also be doneStopMedicineTest, prove that the side effect is reversible (if the side effect disappears very slowly, it indicates that the efficacy has a greater impact on you, you can consider terminating the use of the drug).
4.2 Crazy expiration
After using minoxidil for 2-4 weeks, you will find that your hair drops more. Don't worry, you may be in the crazy period 」.
When your new hair is growing rapidly, the old hair falls off quickly, so more hair will fall off.
Clinical investigation shows that the effect is obvious after 4 months, and 95% of the patients are satisfied after 8 months.
4.3 Re-removal
Let's have a little science popularization. Whether it is finasteride or other drugs, it will have no effect on patients whose hair follicles have been closed, and after leaving the drugs (especially the sudden withdrawal of drugs), they may resume alopecia, is complex off.
Strictly speaking, there is no way to cure alopecia, which requires long-term medication to maintain. If you plan to stop the drug, you also need to reduce the dose at 1.1 points to give the hair time to adapt.

V. Introduction to technology and process of hair transplant

Long ago, the editor thought hair transplant was to plant hair on the scalp (what a simple idea), after gradually understanding the issue of hair transplant, I realized that this is not the case.
Hair transplant plants hair follicles, which are more rigorous. It should be said thatHair follicle unit. What the doctor transplanted to you is a hair follicle unit. A hair follicle unit usually wraps 1 to 4 hairs. The cost of hair transplant is also calculated according to the unit of hair follicle. Generally, about 20 units of hair follicles are needed in the alopecia area per square centimeter.

5.1 The principle of hair transplant
Hair transplant plants are hair follicle units. Here is another knowledge point:Hair at different positions of the head has different sensitivity to hormones.

According to everyone's life experience, whether boys or girls, the hair on the top of their heads and forehead corners is easily affected by hormones and falls off, but the hair on the back of their heads is generally not easy to fall off. Hair transplant is an operation that takes advantage of the characteristic that hair in the back of the brain is not easily disturbed. Generally, hair follicles are taken from the posterior occipital (that is, the posterior brain) for transplantation.

Insert a question"My hair itself is very small, even the hair on the back of my head is not enough...... Can I transplant other people's hair or use artificial hair?"
-- No. Hair transplant is transplanted with hair follicles. If someone else's hair is transplanted, immune rejection may occur. Not only the transplanted hair cannot grow, but also its original hair will drop. In addition, artificial hair was developed in Japan in the 1970 s, but after transplantation, body rejection and long-term inflammatory infection occurred in the human body, resulting in local cicatosis and fibrosis.


5.2 Hair transplant process
Generally speaking, people will receive drug therapy before hair transplant. After the treatment reaches the stage of "no alopecia", they can begin to receive hair transplant surgery.
5.2.1 preoperative preparation
●Physical examination (hematuria test)
●Stop activating blood drugs (including minoxidil)
●Shampoo (HaircutNeed to go to the hospital for haircut by medical staff)
●Time preparation: it is better for patients from other places to go to the hospital one day in advance and go home after a night's rest

5.2.2 intraoperative
●Anesthesia: local anesthesia is generally used, and general anesthesia will be carried out in some cases.
●Hair Follicle Extraction (prone)
●Separated hair follicle
●Hair follicle planting (supine)

5.2.3 postoperative

Points of attention after operation
●Do not touch transplanted hair within 7 days after operation
●Wash hair 3 days after operation

Postoperative recovery
●Generally, it will swell for a week after operation
●Scab skin shedding 10 days after operation
●Hair transplant began to fall off 3 weeks after operation
●It grows again 3-4 months after operation
●The effect gradually reached the best condition 6-12 months after operation

The workload of hair transplant is large (generally about 3,000 units of hair follicles), the operation time is long (4-5 hours for comments), and both doctors and patients are very hard.



5.3 Surgical type and project price of hair transplant
Hair type
According to the hair type, hair transplant is generally divided into two types: "incision" and "non-incision", namely FUT and FUE.
Incision, as the name implies, is to cut the scalp with a scalpel, extract tissue, and then suture the scalp. The removed tissues were separated by hair follicles and then transplanted to the head and top.
●Advantages: it can be extracted in a large area at a time, the operation time is fast, and the hair follicles are not damaged
●Disadvantages: Scars may be left, and the scalp will feel tight after anesthesia
Non-incision is to use hair follicle collector to extract hair follicles from the back occipital one by one, and then transplant them to the top of the head.
Many patients will choose FUE because they are afraid of incision or scar production. But in fact, according to their own situation, choosing the corresponding method is the more appropriate topic selection.
Implant Type
Implantation methods are divided into gem knife, microneedle and hair transplant pen. Doctors usually choose the appropriate implantation method according to their proficiency and convenience, which is usually used in combination of gem knife and microneedle.


Project Price
The unit price of hair follicles for traceless hair transplant surgery in China is generally between 8-12 yuan. The number of hair follicles that each person needs to transplant depends on his or her hair loss grade, and the amount of hair transplant needs to lead to different personal expenses.
Take the FUE technology adopted by an organization as an example. The price per unit of hair follicle is 10 yuan, which is calculated according to the area you need to plant. For example, if you need to plant 2500 units, that is 25000 yuan. At present, many domestic institutions are responsible for preoperative examination and postoperative drugs, so the cost of hair transplant will also include some examination fees and drug costs.

5.4 Are You suitable for hair transplant?

Speaking of which, are you greatly confident in recovering your thick hair? Although hair transplant is the ultimate gospel for alopecia patients, not everyone can do it1. The amount of hair loss per day is large
If the number of patients with hair loss is more than 100 per day, it is recommended to control hair loss through drugs first, and then transplant hair after the hair loss is stable.
2. The quality of the back occipital hair is not good, and the scalp is thick
If your back occipital hair is soft, the hair quality is not good, and the scalp is thick and difficult to cut, the value of surgery is not very big. There are still many such cases, so the hair status before hair transplant is also very important.

3. Hair seam back
Generally speaking, hair alopecia in front of the hair seam is more obvious. If the hair seam is behind, most of them indicate that the healthy hair that can be adopted is relatively limited......
4, disease or taking special drugs
There is a lot of content on this point, and the editor listed a key point:
●Hyperthyroidism and liver disease in unstable phase
●Hepatitis B carriers need to inform in advance for relevant prevention
●You can't plant hair after drinking that day
●Crazy alopecia, alopecia areata, round alopecia areata, no hair transplant
●Scald scar can't be transplanted for less than 6 months
●Take some special drugs (about 40 to 50 kinds, I will not list them)
5. Too young
Don't think it's children who are too young

For alopecia, 25 and 30 years old are relatively young. But for the specific age, each doctor's judgment standard is not special. If you are younger, doctors generally do not recommend hair transplant, unless it is a profession that requires more strict personal image, such as acting as a star.

The above is to judge whether you are suitable for hair transplantation from the perspective of surgery. From the perspective of personal needs, if you expect hair transplant to bring huge image changes to yourself, but the hair volume itself is relatively small, you may need to lower your expectations or choose another way. Because, an average hair transplant operation can only transplant 3,000 units of hair follicles, and one hair follicle contains 1~4 hairs. If the alopecia is severe, only multiple transplants can be performed.


5.5 hospital selection of hair transplant
Regarding the choice of hospital, friends are advised to consider from the following four aspects:

●Regular. With formal medical qualifications, a health license certificate issued by the health department and an operation project license issued by the Ministry of Industry and commerce must be provided.It should be noted that when signing the agreement, attention should be paid to whether the organization will ensure the safety of hair transplant and the survival rate of hair follicles.
●Professional. The professionalism of the organization. OptimizationProfessional hair transplant institutions, followed by the top three hospitals (need to investigate whether the hair transplant project belongs to the outsourcing department), and the beauty hospital containing hair transplant.
●Technology. Technology is the core of determining the effect. Technology is very important in hair transplant surgery. When selecting hair transplant institutions, corresponding technical support should be considered to ensure the operation effect. Don't be blinded by false propaganda.
●Doctor. The quality of doctors is actually counted in technology. The qualifications of doctors and the proficiency of surgery are directly related to the success of hair transplant. The investigation of doctors can be carried out from clinical experience, case feedback, patient public praise and other aspects.
