Answer

PRP has both proliferation-inducing as well as anti-inflammatory effects. A small randomized, double-blind, placebo- and active-controlled, half-head study has shown PRP to be superior to both intra-lesional triamcinolone acetonide and placebo. [59]  While showing promise, more studies are needed. [60]
