I went to Turkey for my hair transplant last year and it was a great experience overall. The cost was significantly lower compared to getting it done in my home country, saving me thousands of dollars. I was also impressed by the quality of care I received at the clinic in Istanbul - the facilities were modern and the staff were very professional.
However, one concern I had was the language barrier at times, as not all staff members spoke fluent English. Also, the recovery time was a bit longer than I expected, so make sure to plan for some downtime after the procedure. Overall, I would recommend considering Turkey for a hair transplant if cost is a major factor for you, just be prepared for some differences in the experience compared to getting it done locally.
