PRP is a product of blood that contains a high concentration of platelets, which are cells that help with clotting and healing. PRP also contains growth factors that can stimulate tissue regeneration and repair .

PRP is made by taking a blood sample from the patient and spinning it in a centrifuge to separate the platelets from other blood components. The platelet-rich plasma is then injected into the target area, such as an injured joint or tendon, or the scalp for hair loss treatment . Sometimes, ultrasound is used to guide the injection.

PRP therapy may help to speed up the healing process, reduce pain, improve function and enhance cosmetic outcomes for various conditions, such as sports injuries, osteoarthritis, wound healing and hair loss . However, PRP therapy is not a cure and may not work for everyone. The results may vary depending on the individual, the type and severity of the condition, and the quality of the PRP product. The risks of PRP therapy are generally low, as it uses the patient’s own blood and does not introduce foreign substances. However, some possible side effects include infection, bleeding, bruising, nerve damage and allergic reaction at the injection site .
