That's because brazilian doctors are not alowed to post before and after pictures, by the law.
So just to clarify you guys, he charges R$5 reais per graft and the average rate is 1 dollar = 2.20 reais... So you can get a hair transplantation of 4000 grafts for something like $8.700 - 9.000 dollars.
And yes, he is a very good doctor, and he performs 4000+ larges secctions too.
Any information just contact me. I'm brazilian and i know the doctor.
