After 25 days of hair transplantation, generally most patients’ hair follicles have been stabilized and become alive, but it cannot be excluded that there are infections or local mechanical injuries during the recovery process of the surgery that lead to individual differences. Hair transplantation generally takes hair follicles from the back of the head as the source of hair, and after separating them into single or multiple follicular units, the hair follicular units are transplanted to the parts that need to be transplanted through fine microsurgical techniques, allowing them to survive in the new parts and grow naturally, so as to achieve the effect of aesthetics. For most people, hair follicles have stabilized after 25 days of hair transplantation. Of course, there are a few people who may be affected by nutrition, infection and other aspects of the hair follicles after 25 days of hair transplantation, there will be a prolonged recovery period or localized transplantation of hair loss and other situations, so it can not be generalized. It is recommended that patients after hair transplantation go to regular hospitals regularly for follow-up to assess the postoperative recovery.
