Hi PGP, I believe Irishrover hasn't posted any pictures from his 2nd procedure yet (only pics just after the transplantation, the bald ones), so we can't really judge anything.
The pictures shown (with long hair) are from his 1st procedure and then it's difficult to draw any conclusions (if it was a succes, back then). Perhaps he's been getting more bald over the past few years.
As for Prohair, they have good results indeed but if any clinic in Belgium is close to Armani then it should be the clinic of Dr.Feriduni.
You know him ?
They are way more expensive than Prohair though.
