Hi
In my opinion, for your age and advanced hair loss level and your donor appears good I think you’re a good candidate for an HT. I’ve seen results from Hair of Istanbul and they look good but it’s mainly from their social media marketing and not from patients themselves so I would be cautious with them or any other clinic where you don’t see many or any patient posts.
If your ht budget is $10k max then I think for the coverage you need, Dr Diep would be out of range for you, unless you do some kind of payment plan with him.
For Turkey, I would suggest you check out current patient results from HLC clinic, Dr Keser, Dr Pekiner, Dr Demirsoy and ASMED, maybe Cinik, and avoid the heavily marketed hair mills.
Good luck!
