By taking advantage of your body’s remarkable healing abilities, Platelet Rich Plasma (PRP) therapy is becoming one of the most effective, scientifically proven hair loss treatments. Platelet Rich Plasma (PRP) is a serum created from your own blood; it’s filled with a concentration of cells called platelets, which are an important healing component of your blood. Platelets are made up of growth factors, proteins and cytokines—all things that help you repair damage and recover from wounds.
