Platelet Rich Plasma (PRP) Therapy | Dr. Joseph Greco Ph.D. Answers Your Questions

[Buckerine11]

Hi Dr. Greco,
One question/concern I have about the PRP procedure is the variability of platelet count in the healthy population. The normal range is 150k-450k/ml. Therefore, for any two people that opt for this treatment, it's possible that they are getting a 3x difference of platelets injected into their scalp. Since we don't know for the certain the mechanism of action of this procedure, it's also possible that there is a threshold of platelets, where any amount of platelets below would not yield any positive results. I think this platelet count variability may be a key contributor to the difference in efficacy that we are observing with this procedure.
What are your thoughts about this?
Thanks.
