I traveled to Istanbul for a hair transplant a few years ago and it was definitely an interesting experience. The cost was much cheaper compared to getting it done in my home country, but make sure to do your research on reputable clinics. I stayed in Istanbul for about a week to allow for the procedure and recovery time, which was enough for me.
The procedure itself went smoothly and the results have been great so far. However, I did have some concerns about communication barriers and post-op care once I returned home. Overall, it was a positive experience, but just be prepared and do your due diligence before making the trip.
