You don't think 5 years is possible anymore even for people willing to pay a premium price?If you think the mouse model means nothing, you don't understand what's happening here. Same goes for Tsuji, that mouse model is not the same as regular hairloss mouse models where they just grow mouse hair on shaved mice. It's cloned human hair on the body of a nude mouse. Alexei (the cofounder who's science this is based on) was the first person to clone a human hair in a lab, period. This sets them apart from basically any other company/process ever except for Tsuji, but these guys are actually funded and organized.
Either way, I'm saying the exact same thing as you. I'm not telling people that this is the end of hairloss and to be overly optimistic. I'm just saying to stop wasting your time/effort debating the process based on single lines of text in an interview. I think Stemson has a really good shot of accomplishing what they set out to, which is to offer us unlimited hair in the future. That future isn't going to be in the next 5~ years though, so don't cling to the idea of them as being some savior to rescue you from your current situation.
