Hi yes I know the Choi NHI Clinic in Athens. I am based in the UK and went to Athens a couple of weeks ago for a procedure. initially I was a little nervous, but I have to say, honestly, the experience was great. The procedure was painless and the clinic team were very professional. The thing that surprised me most, looking back is that this whole thing was not a big deal I had no post-operative pain or swelling and now - nearly three weeks later i'm wondering why I delayed things for so long. If you're thinking of getting a hair transplant I'm sure there are some good places around, but I would recommend NHI in Athens to anyone...go for it guys!
