BACKGROUND Hair graft preservation is an important factor that influences graft survival in hair transplantation. OBJECTIVE To investigate the benefits of adding platelet-rich plasma (PRP), and the effect of different storage solutions and temperatures on hair follicle preservation. MATERIALS AND METHODS This randomized-controlled study included 10 androgenetic alopecia patients who underwent hair transplantation. Forty-five hair grafts were collected from each patient and then randomized to 8 different culture conditions for 7 days. Hair grafts were cultured in Williams' Medium E or Ringer's lactate solution (RLS) at either 4°C or 37°C, and with or without 10% PRP supplementation. RESULTS In vitro hair growth in Williams' Medium E was significantly greater than in RLS. The 37°C temperature condition was found to be significantly better than the 4°C condition. The growth of hair grafts cultured with PRP was not significance difference from those without PRP. However, immunofluorescence staining for cytokeratin 15 showed greater expression in hair graft cultured with PRP. CONCLUSION PRP may have a beneficial effect for preserving the viability of hair grafts. Williams' Medium E and 37°C temperature were found to be superior to RLS and 4°C relative to hair follicle growth in organ culture.
