The follicular extraction technique is usually applied to autologous hair transplantation, with an interval of 3 to 6 months between transplants. Hair transplantation involves surgically redistributing a portion of one’s own hair in areas with less hair or other parts of the body where hair is lacking. The transplanted hair will retain the ability to grow originally and further grow in the transplanted area. Surgical sutures are usually removed 7 to 12 days after the procedure. Waiting until 3 to 6 months after the procedure, the transplanted hair follicles can be observed to see whether they are viable or not, and if the transplantation is viable, the next transplantation can be considered at this time, so the interval between two follicle extractions is 3 to 6 months. After follicle extraction, there may be infection or edema in the transplanted area, etc. If there is any abnormality after follicle extraction, the time for the second surgery will need to be postponed accordingly. It is recommended to go to a regular hospital in time and follow the advice of a specialist.
