I had traumatic experience from DHI years ago. Before the day of the surgery you wouldn't know your doctor. The techs, maybe due to low salaries, are not staying there for long time, so the grafts maybe fitted to your head by a technician undergoing training, who is gonna learn how to fit grafts in your head.
Also the "most advanced technique" of hair extraction (I suppose) doesn't guarantee you natural results, even if it really is the most advanced extraction technique, it doesn't guarantee neither proper scar closure, nor proper incisions or grafts' placement.
There is a local Greek forum, whereby all Greeks undergone HT with DHI are looking for the best repair option.
STAY WELL CLEAR
