Hi, I'm undergoing a hair transplant soon and I'm looking to get full density in my frontal by filling in my temples, The hair in between, and lowering my hairline by only 2-3 cms. My main goal is my mid section/crown, it's been my issue since late teens! How many grafts am I looking for full thick density in mentioned areas? Also what will be my success rate on a 100% scale for just 1 procedure? Looking to get a mega procedure.
