Beard and Body Hair Transplantation by Follicular Unit Excision Using a Skin-Responsive Device: A Multicenter Study

The multicenter study, conducted across four hair restoration clinics in the United States, Colombia, Mexico, and India, evaluated the effectiveness of a skin-responsive follicular unit excision (FUE) device (SRFD) in beard and body hair transplantation. The study involved 82 patients, aged between 29 and 74, who underwent the procedure between May 2022 and February 2023. The results showed that the average graft transection rate (TR) for beard and body FUE was less than 7%, marking a significant improvement over previous methods. The lower TR in beard FUE, compared to body FUE, could be due to its closer resemblance to scalp hair. The study also found that the willingness of surgeons to perform beard and body FUE increased significantly when using the SRFD. The study's strength lies in its multicenter approach and diverse surgeon experiences, but it is limited by its retrospective nature and small sample size.
