Cell therapy – Platelet Rich Plasma (PRP) vs Platelet Rich Fibrin (PRF). Why do some doctors believe that PRF is superiod to PRP in treating hair loss and thinning hair? Both Platelet Rich Plasma (PRP) and Platelet Rich Fibrin (PRF) are non invasive cell based therapies that use the patient’s own blood platelet as growth factors for healthy hair growth.
PRF is superior because it is spun at a lower speed which allows some of the white blood cells and stem cells to remain within the platelet layer that is collected for treatment purposes. Thus, there are more growth or healing factors within PRF. In addition, the lower spin speed causes less trauma to the individual cells of the blood and therefore allowing more stem cells or growth factors to remain in the final plasma. Another key difference between PRP and PRF is the concentration of the platelets.
