I am a 23 year old and I had to undergo radiation therapy for a brain tumor. Most of my hair grew back except for an area where the main focus of the radiation. The hair is a LOT thinner in that area. I've tried Rogaine and had no results and there is no history of baldness if my family. I've been searching for info about my particular situation but havent been able to find anything relevent. So my question would be do they do hair transplantations for people in my situation?
