Design and Clinical Application of Specialized Protective Cap for Patients with Alopecia After Autologous Hair Transplantation

The study investigated the design and application of a specialized protective cap for patients with alopecia after autologous hair transplantation. Conducted from February 2017 to January 2019, it involved 81 patients at the First Affiliated Hospital of Air Force Military Medical University. The cap, made from elastic gauze, fiber, and silica gel, was designed to protect the hair receiving site and apply pressure to the donor site. Results showed that the protective cap significantly reduced postoperative hemorrhage and scalp swelling compared to conventional dressing. Additionally, it improved the survival rate of transplanted hair follicles and patient satisfaction scores. Specifically, only 1 patient in the cap group experienced hemorrhage compared to 8 in the conventional group, and the survival rate of hair follicles was higher in the cap group (94.9±2.8) than in the conventional group (91.1±4.7). The study concluded that the specialized protective cap was beneficial in postoperative care for hair transplantation patients.
