Omarshari,
I understand my friend, but only make such a commitment to a physician if it serves the best interest in your patient care. Now I can't speak for your doctor, but I think in so many words, he is clearly telling you he is inexperienced with FUE, AND NOT THE BEST CHOICE for you. Remember, hair transplant docs in general do not like admitting that they are not that patient's best choice for their particuliar siutation or case. It's like saying, "I am not competent to do that", so and so is better at FUE. When he said he has the instrumentation to do it, that's no guarantee of a good result and yield, and again, I think in so many words, he's telling you that.
Now my real concern for you Omar is the diffused thinning you are noticing in the temporal lobe areas. You describe it as a lower density of coverage, not necessarily recession. And if that's true, you run the risk of shocking out the natural diffused hair that is there in place right now. Trust me, you'll be chasing those areas with more surgery. It's hard to say though. A very small FUE session can enhance the area because there are not as many incisions done which ultimately causes the trauma which promotes and incurs shockloss to the neighboring weak hairs.
For me, it's still too small of a session to get in the chair. Some Toppik could beef up the density, and most people would never know what you are doing. You will need to mist over the Toppik with spray to hold the fibers in place.
Then, eventually you will lose the hair in those weaker frontal areas, and there will be nothing for the Toppik fibers to cling to. That's when you know you are ready to put more grafts up front. See what I mean?
