The effect of plasma rich in growth factors combined with follicular unit extraction surgery for the treatment of hair loss: A pilot study.

This preliminary data demonstrate that PRGF is able to minimize the postsurgical follicle loss and potentiate the performance of grafted hairs. The fibrin clot not only acts as a protective barrier against environmental factors, but also provides a biologically active scaffold that induces resident cell proliferation and maintains an optimal integrity of the grafted hair.
