Is PRP considered 'anti-inflammatory"?

Does PRP stop inflammation?

Is platelet rich plasma (PRP) considered "anti-inflammatory"? and if so - which inflammatory scalp conditions can it be used in?

Platelet rich plasma (PRP) procedures are short 1 hour procedures. They involve taking a patient's blood (generally about 30-120 mL) and spinning in down in a centrifuge type machine to obtain "PRP". From 120 mL of "whole blood", we usually obtain about 3-6 mL of concentrated PRP.



PRP has potential anti-inflammatory properties

PRP has potential anti-inflammatory properties. Studies in the joints and tendons of humans and animals have shown that a protein known as hepatocyte growth factor (HGF) may be responsible for the anti-inflammatory effects. Furthermore studies have shown that PRP can impair the ability of blood cells known as monocytes to differentiate into dendritic cells and activate the immune system.


PRP can sometime create inflammation

Other studies have shown that the white blood cells and neutrophils in PRP can be "pro-inflammatory" in some cases (rather than inhibiting inflammation) so we have a ways to go to understand all the effects of PRP!

We have had an interest in understanding PRP and whether it helps a range of hair loss conditions. For the autoimmune condition alopecia areata, we have published already that PRP can benefit some patients but not everyone. Whether PRP also helps inflammatory scarring alopecias is unknown but something we are very much interested in.
