October 2025 in “Dermatologic Surgery” This study investigated the survival rates of hair follicles with minor trauma, specifically twisted bulbs and fractured shafts, compared to intact follicles after transplantation into the skin of immunodeficient nude mice. The study involved 65 follicles with twisted bulbs, 65 with fractured shafts, and 105 intact follicles. Results showed that the survival rate for twisted bulb follicles (75.00%) was similar to that of intact follicles (73.33%), while fractured follicles had a significantly lower survival rate (33.33%). The study suggests that twisted follicles can be effectively used in follicular unit excision (FUE) surgery without affecting survival rates, potentially reducing losses and increasing transplant efficiency. However, the findings in mice may not directly translate to humans, indicating a need for further research.
