PRP therapy, which takes about 30-40 minutes to complete, begins with the collection of the patient’s blood in a tube. Platelet-rich plasma is used by separating it from other components of whole blood by centrifugation method. Because platelets act as a natural reservoir for growth factors needed to repair injured tissues. Growth factors secreted by platelets stimulate tissue healing by increasing collagen production and gene and protein expression in tendon stem cells. These growth factors also accelerate blood flow and make cartilages more rigid and flexible. PRP injections can be done in different ways. For example, for hair loss, lidocaine, a local numbing solution, is applied if necessary before injecting into the scalp. For this, it may be necessary to come to the treatment session a little early. Usually, PRP is mixed with a local anesthetic to reduce the pain associated with the injection. Sometimes, PRP injection can be done together with the surgical procedure.
