Abstract

CONTEXT:

Platelet-rich plasma (PRP) therapy is finding importance in aesthetic medicine.

AIM:

The objective of this study was to study efficacy of PRP therapy in follicular unit extraction (FUE) hair transplant.

MATERIALS AND METHODS:

It is a single-blind, prospective randomised study on 40 FUE hair transplant subjects, allocated in two groups (PRP and non-PRP) alternately. PRP was injected intra-operatively immediately after creating slits over the recipient area in PRP group; and normal saline in non-PRP group. Two groups were evaluated at 2, 4 and 8 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 12 patients at 4 weeks meaning reduced fall of transplanted hair during catagen phase. New hair growth started at 8 weeks in 16 patients and redness over recipient area completely disappeared in 19 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, four patients had >75% hair regrowth at 6 months; none showed >75% graft density at 4 weeks, and 13 subjects showed dormant follicle activity at 4 months. The number of patients having lengthier hairs was significantly more in PRP group.

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.
