In my dream I was at my Hair Dr.'s office. This older gentleman in front of me... I would say was in his 60s. He was bald in the crown area. The doctor gave him instant injection hair by hair 2 inches long in the balding area.
To continue, I believe the future technology will allow us to do that. Growth of the human hair in the lab and direct injection to your scalp. How far away are we from this? 5, 10, 15 years? I would say 10..
