PRP for Genetic Hair Loss: What is the evidence?

TREATMENT OPTIONS FOR GENETIC HAIR LOSS

Minoxidil and Finasteride are two FDA approved treatments for genetic hair loss. Other treatments like low level laser therapy (LLLT) and platelet rich plasma (PRP) are also possibilities. 

What is PRP?

Platelet rich plasma is a treatment whereby a patient's own blood is used for treating his or her hair loss. We no longer live in a world where we wonder if PRP works. We have now entered an era where we have evidence it does something and now need to figure out how well it works and who it works in.  

To date there have been approximately seven studies on the role of platelet rich plasma in treating genetic hair loss. These studies include:
