Fred, I understand the let down that you felt but sometimes you have to realize that if something doesn't work out the way you hoped then it can actually be a good thing. No one NEEDS to have SMP nor does one NEED to have hair transplantation (unless they need a repair or to fix an injury) but the message take away is that you weren't harmed and a clinic that felt you were not a candidate told you so. I never look at such scenarios as a bad thing as it shows the clinic has ethics. I can name dozens of clinics that would not have been so up front. Remember, you can't be harmed by being turned down.
Were you turned down by this one clinic or were there others? You're in Brussels so I would imagine you consulted with multiple clinics, yes?
