Hair transplant surgery, no matter what technique is used, is usually performed using a local anesthesia along with sedation to make you relaxed and comfortable. Various methods of transplant surgery are available. Your surgeon will choose the surgery most appropriate for you, based on your own circumstances. If general anesthesia is used, you'll sleep through the procedure.
Using needle-free anesthesia the patient is partially or completely anesthetized and does not feel any pain. When the patient wakes up, the operation is completely finished.
