The hair transplant industry in Istanbul, Turkey is reportedly worth more than one-billion US dollars. Every year, over 200,000 people travel there from all over the world in hopes of regaining their hair. However, the industry in Istanbul is very lightly regulated and, therefore, in your average clinic the work will be performed by a technician, not a doctor, which to me rings alarm bells.
While the Turkish Ministry of Health sets industry standards that are in line with EU regulations, there is no obligation for clinics to divulge how many procedures they perform, and membership of medical associations remains voluntary.
