Comparison of Different Methods of Local Anesthesia for Platelet Rich Plasma Injections to Scalp in Patients With Hair Loss - A Prospective Study

This prospective study involving 60 patients compared different methods of local anesthesia for PRP injections to the scalp for hair loss treatment. The study found that vibration anesthesia resulted in the highest intra-procedure pain, while nerve block was the least acceptable due to pain from the anesthetic injection and visible bulging. Post-procedural pain was highest with vibration anesthesia and lowest with ring block, which also had the highest patient acceptance. The study concludes that standardizing the anesthetic protocol, particularly favoring the ring block technique, can significantly improve patient comfort and compliance.
