Platelet rich plasma therapy uses a patient's own platelets to encourage and accelerate healing in a variety of tissues. With the growing popularity of using platelet rich plasma for aesthetic procedures, the need for a book that ties together all of the current literature in one place has become more pressing. This book fills in that gap as a comprehensive guide that covers history, basic science and clinical utility of platelet rich plasma with its uses in hair restoration, facial rejuvenation, and some wound healing. It includes the latest studies/literature from peer reviewed journals and clinical, anecdotal experience. Chapters provide an extensive look at how to describe the mechanism of action of platelet rich plasma (PRP) in the skin and hair; how to identify the difference between PRP, platelet rich fibrin, and stem cells; and identify the various PRP preparation systems and how to calculate dosing.
