Aims and Objectives: The objective of this study was to study efficacy of injectable PRP therapy in follicular unit extraction (FUE) hair transplant.
Method: It is a prospective randomised study on 50 FUE hair transplant subjects, allocated in two groups (PRP and non-PRP) alternately. PRP was
injected immediately post-operatively over the recipient area in PRP group; and normal saline in non-PRP group. Two groups were evaluated at 3, 6
and 9 weeks, 3 and 6 months of the procedure.
Statistical analysis: It was done using Chi-square test and test of significance was set as P < 0.05.
Results: In PRP group, all subjects had >75% hair regrowth at 6 months, density of >75% grafts was noticed in 15 patients at 6 weeks meaning
reduced fall of transplanted hair during catagen phase. New hair growth started at 8 weeks in 12 patients and redness over recipient area completely
disappeared in 20 patients at 3 months of surgery and activity in dormant follicles as fine thread like hair was noticed besides the thick transplanted
hair in all subjects. In non-PRP group, five patients had >75% hair regrowth at 6 months and none showed >75% graft density at 4 weeks.
Conclusion: Intra-operative PRP therapy is beneficial in giving faster density, reducing the catagen loss of transplanted hair, recovering the skin
faster and activating dormant follicles in FUE transplant subjects.
