Although a shiny scalp is often said to be a symbol of a wise person, no bald person would like to have thinning hair, or a head or temples that are hard and less hairy than others. Hair loss is a worry for both men and women, and for women, it is an unbearable blow in their lives. Happily, with the development of medical technology, hair transplantation can make up for the regrets of people with hair loss. Hair follicle transplantation is like inserting a rice plant The vast majority of patients’ hair loss occurs at the top of the head, with good hair on both sides and in the back of the circle. This phenomenon is caused by the different structure of the hair follicles. Because the hair follicles on the top of the head have structural congenital defects, they are subject to degeneration and necrosis by various factors such as endocrine disorders, environmental factors, mental stress, etc.; because the scalp area with necrotic hair follicles is like a fertile land without seeds, even if there are rich nutrients and abundant rain, it is impossible to make this land grow new shoots. In contrast, the hair follicles on the two temporal sides and the back of the occipital area have a normal structure unaffected by various acquired hair loss factors and do not undergo degenerative necrosis throughout their lives. “Dealing with permanent baldness can only be improved by hair transplantation. The hair transplant we usually hear about is actually an autologous hair transplant, that is, taking hair and hair follicles from your own hair area (usually in the back of the occipital area) and ‘planting’ them into the bald area, ‘tearing down the east wall to make up for the west wall’, the principle is just like planting rice. ” There are many surgical methods of hair transplantation, such as single transplantation, multiple transplantation, scalp-hair composite tissue free transplantation and scalp flap transplantation. The method used by more hospitals now is “autologous hair follicle transplantation”, and the technology has become very mature by now. Hair transplantation is needed for genetic and burn hair loss. Women who need hair transplantation for hair loss are usually patients with seborrheic alopecia, which is the mainstream group of women for this surgery. Although seborrheic alopecia occurs mainly in men, there has been an increase in the number of female patients in recent years, which is considered by medical experts to be genetically related. Most female baldness occurs in the crown area, mostly with increasingly thinning hair density, and female baldness generally occurs later and at a slower rate than in men. Some people who have been burned or scalded can also develop scattered areas of traumatic scarring hair loss due to necrosis of hair follicles from burns, scalds, and electrical injuries. All of these cases can be tried to improve by hair transplantation. Only 30% of female patients are suitable for hair transplantation Female hair loss patients have many deficiencies compared to men, and some women with hair loss are unable to solve the problem through hair transplantation. To determine the suitability for hair transplantation, the first thing to look at is the density of hair in the area where the hair follicles are taken. If the donor area has less than 15 follicular units per square centimeter, it is not suitable for hair transplantation. The higher the density of hair follicles in the donor area, the better the result after transplantation, normally 50 grafts per square centimeter is basically enough. The surgery is delicate and takes nearly 5 hours. The seemingly simple hair transplantation surgery is not easy at all. There are not many hospitals that do hair transplant surgery, because the surgery requires skill and patience, and each surgery takes more than 5 hours. During the surgery, the doctor first cuts a 1-2 cm wide, about 20 cm long flap with healthy hair follicles from the left ear to the right ear behind the hair transplant, sutures the wound, then divides these follicles into smaller units, makes a microscopic incision on the top of the patient’s head where the hair loss occurs, and then plants the graft into the area of hair loss. Generally, the cut flaps are sufficient for transplantation, with 2-3 hairs as the splitting specification with the help of a magnifying glass to split into a single graft, which must not be too large, otherwise it will form a handful, unnatural and ineffective. After splitting, there are nearly 2,000 grafts in a 40 square centimeter flap, which is nearly 7,000 hairs to meet the transplantation needs. In addition to treating permanent hair loss on the scalp, this technique can also perform reconstruction of eyebrows, eyelashes, male beard and pubic hair, and hair follicle transplantation at burns, burns and trauma scars can achieve good clinical results. New hair can be freely permed and dyed Perhaps many patients are concerned about the safety of hair transplantation. This is a delicate and advanced cosmetic surgery, which is superficial and very safe. The surgery has a very low infection rate, minimal trauma and a high success rate. Patients do not need to be hospitalized and can usually shampoo their hair on the 4th day after surgery and return to full normalcy after 10 days. New hair starts to grow after 3 months of surgery and the initial results can be seen after 6 months. Moreover, the new hair grown after hair transplantation can be blown out, permed and colored normally. However, after transplantation, patients still need to apply related medication to ensure that the hair on the top of the original head will not fall out again and that the transplantation effect will be maintained.
