The process of autologous hair transplantation involves three steps: FUE follicle extraction, follicle trimming, and follicle implantation. The purpose of follicle trimming is to improve the efficiency of follicle implantation and enhance the immediate postoperative aesthetic appearance. Therefore, during the follicle trimming process, the sebaceous glands and above-mentioned epidermis, partial dermis tissue, and surrounding tissue of the follicles are usually separated and discarded, and the remaining follicle tissue is implanted into the recipient area. The investigator collectively refers to the discarded tissue as hair follicle-derived microtissue (HFMT). In a clinical case, The investigator accidentally discovered that if the HFMT obtained from the follicular unit extraction (FUE) method was collected, cut into pieces, and made into tissue homogenate, and then the HFMT homogenate was used to cover the FUE donor area wound, the patient reported reduced postoperative pain and some relief from skin itching. Additionally, compared to conventionally treated wounds, the wound in the donor area healed faster. Based on these findings, this study aims to compare the effects of HFMT on the healing of FUE donor area wounds.
Autologous hair transplantation involves follicle extraction, trimming, and implantation. Follicle trimming improves efficiency and postoperative appearance, resulting in the discarded tissue known as hair follicle-derived microtissue (HFMT).

This study aims to compare the effects of HFMT on FUE donor area wound healing.
