I'm doing research for my first hair transplant and I'm learning that the scalp gets inflated (I think called Tumescence). Do all surgeons do this and if so, both during extraction and during placement? Do they all inflate at the same level? Also, regarding pain management, I assumed all clinics use anesthesia but I'm finding that they all have different methods for pain management. The differences likely may be in different countries. What is the preferred method that I should look for before I select a clinic?
