As an Irishman who suffered at the hands of a certain hair transplant surgeon in Ireland about 15 years ago, I have some experience. If I was to get work done in Ireland again, it would be the Blackrock clinic Dublin with Dr Maurice Collins. I've had two consultations in an 18 month period, no gimmicks, no salesman stuff, he is thorough, takes lots of photos, will prescribe propecia and insist you go away and think about things for atleast six months before he proceeds. My first transplant was sold to me by a man in a suit in some downstairs office that told me applying minodoxil to my head was akin to taking bleach or window cleaner from the kitchen and putting it on my head. He also told me a hairdresser would never be able to detect my donor scar. Complete BS.
Dr Collins is in another league. I think he did Louis Walsh's hair and that Irish actor Nesbitt from up north. In saying that, I don't know how he compares with British/European surgeons. His premises is top notch. Looks and feels very professional.
The downside for me, well there are two, he is bloody, bloody expensive and only does FUT.
Do lots of research. I am currently considering Farjo in England or a couple of the Belgian surgeons mentioned on this site.
Again, do lots of homework before you jump in.
