If one is going bald, then it's often less than $10k. How do I know? Because I've had a marginally receding hairline (that hasn't moved in about 6-7 years) and I've met with top hair transplant specialists in the NY/Boston area and Toronto/Ottawa area.
In all honesty, I have researched this, and I know that a transplant is the way to go if you're going to do it. It's really not a huge stigma for me since baldness runs in my family, but not everyone of us goes bald and I was hoping it would skip me. In the end, I decided just to accept it. I'd much rather go bald than give up hobbying!
