The Plastic Surgery and Regenerative Surgery Unit, the Second Clinical Dermatology Unit, the Health Services Research Unit, IDI-IRCCS, Rome, Italy and the Greco Medical Group, Sarasota, Florida did this study.

It was supported the Italian Ministry of Health in 2012-2013 and Published by the American Society for Dermatologic Surgery, Inc. in The Journal of Dermatologic Surgery, Sept, 2014.

RESULTS: Sixty-four consecutive patients were enrolled. Some improvement was seen in all patients by 1 evaluator and in 62 by the other. The mean change in clinical rating was 3.2 (95% confidence interval [CI], 2.9– 3.5) and 3.9 (95% CI, 3.5–4.3), and the proportion of patients reaching a clinically important difference was 40.6% and 54.7%, according to the 2 evaluators, respectively.

In simple terms, we now know the growth factors or proteins in PRP:

  1. Play a key role in communication with the stem cells in the hair shaft to initiate the hair cycle
  2. Play 
a role in hair canal formation
  3. Control of hair growth and follicle size.
  4. Stimulating hair growth by prolonging the anagen phase (growth phase) of the hair cycle.
  5. Increase hair shaft diameter
  6. Increased vessels around follicles
