Platelet Rich Plasma
Platelet Rich Plasma (PRP) in Hair Restoration
Platelets are one of the components of the human blood system. They are circulating in the vasculature along with red and white blood cells. Platelets participate in the blood clotting system and function to stop bleeding at an injury site and assist in the initial process of wound healing. There are many biochemical factors contained within the platelet which are immediately released at an injury site. These factors include Platelet-Derived Growth Factor (PDGF), Vascular Endothelial Growth Factor (VEGF), Epidermal Growth Factor (EGF) and Fibroblast Growth Factor-2 (FGF-2) among several other healing and growth factors. The combination of these biochemical growth factors initiate and enhance the body’s process of healing and tissue recovery after injury.
Since platelets are contained in the blood system they can be easily harvested from a patient’s own blood. A tube of blood can be drawn from the patient then placed into a centrifuge which spins the blood to separate it into the various components of the blood system. The separated layer containing the concentrated platelets is considered the “platelet rich plasma” or PRP. This layer is removed and can be used in various medical situations in order to enhance tissue regeneration and healing. Platelet rich plasma has been used for many years to assist in the healing process. It has been primarily used in the hospital setting in various operative orthopedic procedures. Recently the process has been used in other areas of medicine and surgery with favorable results.
The stimulation of tissue regeneration and enhanced healing properties of PRP has recently been used in various areas of hair restoration. It has been found to be helpful in preserving the viability of hair follicle grafts during hair transplant procedures and to enhance the tissue healing and promote hair growth in transplanted follicles. These benefits can result in improved graft survival and better hair transplantoutcomes.
