Some time ago, I sent photographs to a hair transplant doctor for an online consultation. I guess you can say that I am fortunate at this point because I still have some hair but am severely diffuse thinning and my hairline has receded by about an inch. The doctor had informed me that any surgery that I would have now would lead to shock loss and I would inevitably yield about what I currently have. Now, I have been told this on a couple of other occasions from other doctors as well. Here is my confusion and question about this. If shock loss is in fact such an issue, then how can some people go for 2 or 3 surgeries a year or 2 apart to improve density? If shock loss is an issue with someone who has diffuse thinning and the doctor believes that any new transplanted hair will kill the surrounding, then how can it not be for a second or third surgery to improve density?
