That's a load of "smelly stuff."
I went the full route in Sherman Oaks, CA and paid a fortune. I chose them for the exact reasons you stated. After paying I met the dead 1 inch bug on the floor, realized that their contract sales girl had lied throughout the introduction process and only saw the doctor 3 time during the procedure. The technicians did the bulk of the work.
This was a "top quality" office according to everything I saw in my research.
I will admit that the risk is higher going to Mexico...that's common sense.
But having had a couple other cosmetic procedures (rhinoplasty (nose job) and one other process) in the Pacific Northwest, I can say that compared to real procedures....
FUT hair transplant, technically speaking is more like going to a dentist.
