If it's not serious, about 500 will be enough. If it's moderate, two or three thousand. If it's serious, it's about 10 thousand!
Don't be fooled by some small advertisements, look for big hospitals!
The hair transplant we are talking about is actually an autologous hair transplant. To put it bluntly, hair and hair follicles are taken out from the hair area and "planted" in the bald area, which is what people often say, "robbing Peter to pay Paul". There are many surgical methods of hair transplantation, such as single-plant transplantation, multi-plant transplantation, scalp-hair composite tissue free transplantation, scalp flap transplantation and so on. Single plant transplantation is suitable for non-traumatic alopecia. Cut off the whole scalp in a small area with hair follicles, carefully separate a single hair with hair follicles and put it into a special instrument. Finally, plant it in a bald place like a rice transplant. The advantages of this method are uniform hair transplantation, little damage to donor site, adjustable hair growth direction and optional hair quality. Its disadvantages are complex operation and low efficiency, and it often needs to be repeated many times to achieve the ideal effect. Multi-plant transplantation can improve the efficiency of hair transplantation, but it is not easy to control and adjust the growth direction of hair. If there are too many plants, the hair will grow out of order, which will affect the appearance. Free scalp tissue transplantation or hair flap transplantation with hair head is mainly suitable for traumatic cicatricial alopecia. After scar resection, skin flap or expanded skin flap transplantation can cover the bald area in a large area at one time, but it destroys the distribution and direction of normal hair, and the hair growth direction is irregular, so the patient can only keep long and messy hair, which is not very beautiful in appearance.
It is worth mentioning that in recent years, with the wide application of laser technology in the medical field, laser hair transplantation has gradually developed in China and achieved good results. Laser hair transplantation is a combination of carbon dioxide ultra-pulse laser and computer for hair transplantation. First prepare the bald area (implant area). Driven by the computer, the laser head completes the uniform movement and cutting of the laser spot according to the bald area and the hair growth direction, thus generating an accurate and uniform hair transplant cutting line. The donor sites are mainly in the occipital region and temporal region of the head. Under local anesthesia, a 3 mm wide slit was made with a carbon dioxide laser knife. Then the 3 mm wide strip is divided into 5-7 hair groups and embedded in the cutting line of the implantation area. After the graft survives, the hair can grow in the bald area. The most obvious advantages of laser hair transplantation are less bleeding during operation and less edema and pain after operation. At the same time, because the transplanted block is small, from the aesthetic point of view, the contrast with the surrounding bald or sparse areas and transplanted blocks is small, and it still presents a natural appearance without too dense transplantation. In a word, laser hair transplantation can greatly improve the accuracy of the operation, shorten the operation time and have a natural appearance.
