Photothermal Biomodulated Platelet-Rich Plasma Improves Preservation of Hair Grafts and Extends Their Viability

The study investigated the use of photothermal biomodulated platelet-rich plasma (PRP) as a preservation solution for hair grafts, aiming to extend their viability before transplantation. Conducted with 28 male volunteers, the research found that hair grafts preserved in MCT Plasma/PBS remained viable for 8 hours, 2 hours longer than those preserved in standard solutions like saline solution (SS) or Ringer's lactate (RL). This enhanced viability is attributed to the improved properties of PRP through photothermal biostimulation, which increases the release of growth factors and cytokines. The findings suggest that preconditioned PRP can effectively mimic the scalp environment, making it a promising option for adapting preservation solutions to modern hair transplantation techniques. Further research is recommended to explore its potential benefits in clinical settings.
