“…Several studies have investigated effects of different preservation conditions on the protection of hair grafts (overview in See Supplemental Digital Content 1 , Table S1, http://links.lww.com/DSS/B257). The chilled preservation temperature is the primary determinant of graft viability, 11,19–21 which slows metabolism to avoid ischemic injury. In addition, the authors have previously explored the optimum temperature for isolated hair grafts, and results showed 4°C kept the best survival rate compared with room temperature.…”

Background: Large area androgenic alopecia patients seeking hair transplantation treatment has become common. FUE Megasession has become a choice for more and more people. Long-term in vitro preservation of hair follicles during FUE Megasession has become a new challenge. Objective: To explore optimal in vitro preservation condition according to FUE Megasession long-period surgery time and to perform clinical practice to confirm the feasibility. Methods: Human follicles were obtained from informed patients by FUE Megasession and preserved under different conditions. Live and dead staining with DAPI was used to assess the survival rate of cells. Hair follicles were preserved in vitro for 7 days under different conditions, and the extension of the hair shaft was observed. We also performed some clinical procedures to illustrate the effectiveness of these methods. Results: Under the condition of 4℃ Ringer's solution, the death rate of hair follicle cells was lower than that of the rest. 4℃ Ringer's solution supported superior growth of the hair follicle unit according to organ culture. 8-h preservation in 4℃ Ringer's solution was kept as high survival rate as the traditional hair transplantation surgery(P > .05). Clinical procedures confirmed the feasibility of FUE Megasession hair transplantation surgery. Conclusion: 4℃ Ringer's solution in vitro preservation is optimal for clinical FUE Megasession surgery which ensures the hair follicle survival rate and postoperative results.

How Long Can Hair Follicle Units Be Preserved at 0 and 4°C for Delayed Transplant?

Abstract: Grafts are better preserved at 0 degrees C instead of 4 degrees C. When delayed transplant is an option, it should be completed within 24 hours and no later than 48 hours.
