Platelet rich plasma (PRP) for the treatment of genetic hair loss

PRP for the treatment of genetic hair loss


Platelet rich plasma or "PRP" is a non surgical method of treating hair loss for men and women.   PRP relies on the growth factors in a patient's own blood to help stimulate hair growth.  A number of studies have been published supporting its effectiveness in treating genetic hair loss. Both my Vancouver and Toronto practices offer PRP. 

How is PRP performed?

As part of our protocol, 120 mL of blood is taken from the patient and spun down (centrifuged) for 15-20 minutes. During that time the patient's scalp is numbed with local anesthetics so that the PRP injections will be more comfortable.

From start to finish, a PRP session takes 45-60 minutes. PRP does not help everyone, but helps 30-40 % of men and women with genetic hair loss. I also use for patients with alopecia areata, and less commonly for patients with telogen effluvium and scarring alopecia.  

 We just finished publishing a report on PRP in the journal called JAAD Case Reports and more are underway as we learn more and more about PRP in treating hair loss.
