Just depends.
I had a hair transplant done in Turkey about five years ago. It made a big difference, although I'll probably fly black for a second procedure at some point in the not-so-distant future. To try to answer your question, OP, there are a lot of clinics in Istanbul, and there's a pretty significant variation in prices and rates. Most reputable clinics will probably charge anywhere between $1,500 and $3,500, with some better-known surgeons setting higher rates.
I had a hospital in Bursa do my transplant, and I think I paid a grand total of about $850. I spent a half-day getting my head poked and then it was over. The whole process, including recovery, was much less intense than I thought it'd be. I mean, you'll look like a fucking space alien for the first few days, but you shouldn't be doing much in those first few days, either.
FWIW, I probably got an unusually cheap rate because (a) this was five years ago, but more importantly, (b), the rate was pre-negotiated by a Turkish-speaking friend who did his transplant the day before me and whose uncle had gone there, too.
