The top part will be debated forever and ever as people have differing opinions on benefits and drawbacks. However, the main reason we can debate these different talking points is we are fortunate to be given a great source of information that allows us to make a better, more informed final decision.
If you took the random guy who did no research, the first question that will be brought up and the decision to be made will be do I want a linear scar are not. Then if the surgeon compares horrific scarring from strip procedures dating back years ago and even right up to this moment now - it will put anyone off. I am not saying that surgeons on here do that but I am talking about selling a hair transplant as a procedure around the world to an individual who has little knowledge about hair restoration. Even though forums are popular, the number of patients coming from forums going to have hair transplants globally is I am guessing a pretty small proportion and hence most will be not fully informed.
There is so much information you need to process in my opinion when getting a hair transplant as the problem is not resolved there and then - it is an on going battle.
