A Brief Study Examining the Variability of Platelet-Rich Plasma with Different Preparation Systems

The study, conducted 5 years ago, examined the variability of platelet-rich plasma (PRP) concentrations produced by four different commercially available systems. PRP has been used to improve hair growth and limit hair loss, with the belief that growth factors attached to platelets can promote hair growth and reactivate senescent hair follicles. However, the response to this treatment has been inconsistent, possibly due to differences in platelet concentrations depending on the PRP system used. The study found a wide variance in platelet concentrations among the different systems when compared to the whole blood concentration of platelets in each patient.
