The forehead moved up severely and most of the hair follicles were closed. After the hair follicles were tested, hair growth cap  Mr. Miao finally decided to choose hair transplant surgery. After a series of examinations, the doctor determined that Mr. Miao was eligible for the hair transplant operation. Before the operation, the doctor informed him about the hair transplant and mentioned that there will be a fall-off period about two to three weeks after the surgery, but it will not affect the effect of the hair transplant. After the period is over, new hair will grow from the hair follicles.

If the hair falls off after the hair transplant, it is the failure of the hair transplant? The reason behind it is the replacement period.

On the 17th day of the operation, Mr. Miao found that part of the hair in the planting area had begun to fall out. He realized that the shedding period may have already started. Although the doctor told him in advance that there would be no problem, he was still worried that the newly planted hair follicles would fall off along with it.

Why does hair fall off after hair transplant? Professor Wu Wenyu, chief physician of the Department of Dermatology, Huashan Hospital Affiliated to Fudan University, said that hair follicles have a replacement period of 1-3 months. A few days after hair transplantation, the transplanted hair will grow out, but the "life" of these hairs is very short. In most people with hair transplants, the hair in the hair transplant area will fall off in the next 1 to 3 months, and then relatively fine vellus hair will grow.

For patients, it is easy to cause psychological panic when they do not understand the postoperative replacement period and the related problems and nursing work that occur after the operation. "Did the hair transplant fail?", "Did the hair follicles fall off?", "Can the lost hair grow longer?" A series of problems bothered the hair transplant patients, and even caused the patients to have cognitive misunderstandings and improper measures. The hair follicles are in poor survival condition.

Hair loss after surgery is normal, not all transplanted hair follicles will fall off

Professor Hu Zhiqi, director of the Plastic Surgery Department of Nanfang Hospital, pointed out that in the early postoperative period, hair loss is an inevitable normal phenomenon due to the damage and influence of the operation and the regularity of hair growth. And the time of hair loss varies from person to person, and it will last for 3 months at the latest. Facing the replacement period, Professor Hu Zhiqi said that there is no need to be nervous, maintain a good attitude, and do postoperative care according to the doctor’s instructions. Growth period.

So will all the hairs in the transplanted follicles fall off at the same time? In fact, about 80% of the new hair will fall off one after another, and the ones that do not fall off will grow directly. Since the hair follicle is transplanted to the planting area together with the hair shaft, the nutrient supply and loss after the transplantation causes the hair shaft to fall off, but the hair follicle does not fall off. After the hair follicle establishes its own blood circulation system and adapts to the transplant environment, it will grow New hair.

The back occiput is "longevity hair follicles", the newly grown hair in the hair transplant area will not fall off

Have never been followed up and lost, which one is more painful? With the advantages of quick effect and wide application, hair transplantation has become the last "straw" for patients with hair loss. After the replacement period, the most anxious thing for patients is "new hair transplantation area". Will it fall off when it comes out"?

First of all, the theory of hair transplantation lies in the donor advantage theory proposed by Norman Orentreich: hair will retain its original characteristics, and the characteristics of the hair are determined by where it came from (posterior occipital donor), not where it was transplanted (forehead) And hair loss on the top of the head). That is to say, the hair follicles in the posterior occiput can grow normally after being transplanted to the forehead or top of the head without the influence of androgens.

Professor Wu Wenyu said that the main causes of hair loss are physiological and pathological factors. For hair transplant patients, their posterior occipital hair follicles are "not cold" to androgens, so physiological hair loss will occur after transplantation of occipital hair follicles. , But generally will not lose hair due to the influence of androgens. The transplanted hair, like the original hair, must participate in the normal metabolism. The hair has a growth cycle and will fall off after entering the resting period. But as long as the hair follicles are healthy, new hair will grow back. That is to say, the newly grown hair in the hair transplant area will only show physiological alopecia, but the hair follicles will not shrink and close.

Systematic maintenance is still required after the operation to prevent the formation of faults on the top of the head

For hair transplant patients, although hair transplantation seems to be "once and forever", it is the transplanted hair follicles that can control the loss of hair, not the original hair. Therefore, after the hair transplant, systemic treatment and maintenance are still needed to ensure the loss of the original hair. , To prevent the formation of faults on the top of the head, resulting in ineffective hair transplantation.

Professor Hu Zhiqi said that hair transplantation is not a one-time fix, and it also requires a combination of medical care. Such a comprehensive treatment can achieve a very good effect, especially for patients with higher levels of hair loss. It is necessary to maintain and improve the scalp environment to a normal level before hair removal. After hair transplantation, it is also necessary to adhere to comprehensive maintenance and comprehensive treatment. Only in this way can a better hair transplant effect be maintained. If it is a disease of hair loss, it needs more care.

Therefore, what patients need is not a single hair transplant operation, but a series of complete one-stop services around "hair" including drug treatment, maintenance services, post-operative care, etc. This also requires the hair transplant hospital to continuously improve its own medical services. .

"Faced with the problem of the replacement period, on the one hand, the public has a lack of understanding of hair transplantation, on the other hand, doctors need to inform the patients in time, and regularly review after the operation to guide the patients to deal with this problem." Zhang Chunjie, dean of the New Hair Planting Research Institute, believes that hair transplant hospitals and doctors should increase science popularization to help the public establish a correct and complete understanding of hair health.
