I had a hair transplant 1 year ago and lost the hair that was there and no new hair grew since (Photo)

It appears that all of the native hair was lost from the surgery (before photo on the left and after on the right)and that your hair transplant was a failure. I always tell my patients that to hold on to their native hair, then should go on the drug finasteride,  Go back and meet with your surgeon? and your surgeon should make it right for you.
