Spend some time here looking at the Drs/Clinics that are being recommended, not just by the forum itself, but also from other members, some really good choices in Europe and further afield.
Apart from the names I already seen mentioned I also see good work from Heitmann, Fuegenix, Pittella and @DrTBarghouthi.
Yeh the question gets posted often, the most common being “please best/cheap transplant in Turkey/Istanbul” but at least you’re considering travelling elsewhere.
What’s you’re own situation, are you on meds? How old are you? You was quoted a lot of grafts so I’m guessing you have extensive baldness already.
