I don't think this doctor is well known on this forum. I would take the instagram results with a grain of salt as the clnic will cherry pick what they post - Impartial results posted by patients are a better indicator of the quality of a doctor
Wow the results from your first transplant are very disappointing. Which doctor performed it? Graft placement looks a little spare on your 2nd transplant, 800 grafts isn't a lot however.
I'd recommend a 3rd transplant for some added density for sure
