This is a complicated question. As I see it, the answer depends on your age, your family history, the extent of your present hair loss, what steps you plan to take to prevent (as much as possible) ongoing hair loss, and what you mean by “going bald”. I'd also be interested to know what you mean by “turned out just fine”—i.e., how old was that someone you know personally at the time of his transplant, and how old is he now? 34? 43? 56? The basic principle to understand is that a hair transplant doesn’t “nip it in the bud” as far as future hair loss is concerned—it simply replaces some of the hair that has already been lost with permanent, DHT-resistant follicles. So you won't lose your transplanted hair. But unless you are proactive (and the jury is still out with regard to PRP), you will lose just as much of your non-transplanted hair in the years after a hair transplant as you would if you hadn’t had one. The question is, what is your genetic destiny, how effective will preventive measures be, and how abundant is your donor area? You might very well be one of those younger men who continues losing very little hair and gets a lot of mileage out of a single procedure; you might need further surgery as you age; or you could be a young man who is genetically programmed to end up like Dr. Phil or Steve Harvey, in which case your demand will exceed your supply—no amount of surgery will be able to cover the entire bald area because the total number of follicles needed has exceeded the supply of donor follicles. The younger you are, the cloudier the crystal ball is. This is why most experienced hair transplant surgeons advise against transplanting young (< 25 years old) men in the early stages of hair loss. Thanks for your excellent and important question. I don’t know if my answer was helpful, but I gave it my best shot. Dr. B
