Nick, I don't want to be negative here but if a hair clinic says "you are a great candidate!" basic on some picture and WITHOUT even knowing if you're on finasteride, that's actually a huge red flag. They just want you to pay for the treatment, make their money and don't care what happens to you in the future. Your judgment is being clouded by the fact that you WANT to be a great candidate.
The fact that the harley doctor doesn't even wanna see you unless you're on finasteride is actually a good thing. Sure, he could've looked into your case and told you to get on finasteride first, but the idea is the same.
Now they probably care only about their own reputation and not about your well-being, but ask yourself: why do they not even wanna consider you without finasteride? Because it's going to be a disaster, that's why. What makes you think that all the hair you have left will stay? It won't, you will lose it like the rest until you're slick bald. Anything you get transplanted right now has to be able to be presentable on its own. What will end up happening is you having a patch of transplanted hair in an otherwise bald head.
Like someone suggested earlier, go to some other respected doctors IN PERSON and ASK them straight up to be honest with you. A ticket from London to Brussels is about 100 bucks. If that ain't worth it to you, then something's seriously wrong.
