It could very well approach the $100K mark when you consider traveling to Japan, staying there for 3 or so weeks (or traveling back and forth, since it will take ~ 3 weeks to culture the cells), etc. Plus, it will only be offered in a small scale at first, and treatments are always more expensive in the beginning. Especially if pricing is structured like transplants, since they'll be using surgeons to implant the follicles IIRC.
Who knows if they'll start the US or Euro approval process quickly, if ever, but if so it might be easier to just wait and get it there.
