What is "Technical Hairs" and who does it?

[Baldnessfalls]

I was reading this thread: http://www.baldtruthtalk.com/showthread.php?t=149 and it intrigued me. I'm interested in any approach/method that can put hair back on my head in as short amount of time as humanly possible. So can someone tell me what this doctor is referring to? What companies do this sort of thing? And how viable of an option is it? I'm a male with nearly a NW3 hairline.

Thanks to anyone who answers!
