Poor growth can occur from both FUT and FUE. In some instances, the scalp is not healthy, which means is has a skin disease. In other instances, the team doing your surgery is not very good. They harvest grafts poorly, damage them on extraction, and damage them on re-insertion into the scalp. This is common with FUE perhaps more so than with FUT. There has been a trend in the hair restoration industry for physicians lacking the skills to perform hair restoration surgery to allow assistants without formal medical training to do the entire hair restoration surgery procedure. This trend has resulted in some very bad results. Therefore, if you are going in for a second surgery, make sure the physician is going to do your procedure. If he has the ARTAS robot, run, don't walk out the door. ARTAS can result in almost no growth and destroy a donor area in one pass. Only physicians lacking in good hand eye coordination use the ARTAS. Avoid these doctors entirely. If the surgeon is going to allow assistants to do the surgery, decline his offer and go somewhere else. Find out how many FUE procedures the physician has done and how long he has been doing FUE. If he has been doing exclusive or his practice has been devoted to at least 90% FUE for 10 years, you might consider him unless he had extensive training with a physician with over 10 years of FUE experience. These are some general guidelines to govern your next decision. If you had bad results, find out why. Was it a skin disease or was it poor surgical skill. I would probably not do a large session next. You should find a top quality physician and have a workup for a skin disease if it appears you have one and then do a test session to make sure you can get good growth. Sometimes, bad work results in poor growth and then poisons the scalp for the rest of your life such that nothing will grow. Ultimately, it's better to find a skilled physician in FUE for the first procedure rather than to avoid doing good homework on your physician before your first procedure.
