This is what I was trying to say in the other Tsuji thread but people were freaking out over it. Sorry to be "negative" but this is the reality. I think people just don't know how all this works.
You can read about the stages of clinical testing here:
https://en.wikipedia.org/wiki/Phases_of_clinical_research
To summarize, it is a three to four phase process, each of which costs tens of millions of dollars and usually takes at least a year or more.
At this point, as far as we know, Tsuji hasn't even have a single replicated human follicle. Let alone a proven method to mass produce them. So he is nowhere near even beginning Phase 1-3 testing. He's still in the purely experimental and theoretical stage still.
Japan has tight regulations on drugs and medicine, as they are an advanced nation. It's not like he's running this enterprise in Columbia where he might be able to skip all that regulatory testing.
I can't see how any commercially available form of this will be available before 2022. And that's IF he solves the hair cloning problem AND works out a method for mass production of them in the next year. Even that is a tall order to expect.
Then do you want to be one of the first guinnea pigs for lab created hair follicles? Will you feel confident knowing the processes he undertook to create those follicles (artificial multiplication and manipulation of stem cells) won't put those follicles at risk of becoming defective over time? Or developing into tumors or increasing skin cancer rates in the scalp?
Personally, I wouldn't let the technology touch my scalp until I saw at least 5 years of safety data from it.
Everyone should still be hitting topical/systemic antiandrogens and stimulants like minoxidil hard. If you think Tsuji gives you an excuse to get lazy and just let yourself go bald since he'll have a magic cure in a year or two you're nuts.
Now for real. I trust the lotion. Not the company producing it. And having something working for all alopecia suspects would be great.
