You said a hair transplant costs $2000 in your country, how many grafts did you get for that price? 2K is on the low, most basic, end of the price spectrum - so you must have gotten the least grafts. If you get the maximum number of grafts, for the most fullest head of hair possible, it can get very costly.
One full strip from your donor area. It depends on the dense of your hair at the back. Mine was about 2000 graft.
$1/graft - that's a very good price. In the US, the lowest price I can find is $3/graft X 2000 = 6K USD
