Dr Jeffery Epstein in Florida does both hair transplants to lower the forehead AND the hair line advancement surgery .
this is his website: http://www.foundhair.com/
I personally used a doctor in Arizona because it was closest to me. But, in my research Dr. Epsteins name kept coming up as a skilled doctor in this field.
Good luck. I just received the hair transplants in April for the same reason; A high forehead. Pictures of my album are on this site. I am posting updates each month.
