Sorry but this has been here dozen times before. Basically you are saying if miracle happens then we are cured. But so far it never did. There were similar situations and all failed. Most of them failed because it worked in animals better then in humans. There is no reason to think that follica will be different.
As far as I know FDA grants permision for a specific purpose. If they want to use the stuff in a new way they will need to ask again and then it is up to FDA to decide if trials are needed or not.
I doubt that FDA will just let them go with scraping ppls heads and throwing some growth stuff into the wounds without testing it properly. I know that in theory the ingredients could have been already allowed for other uses. It does not mean though that FDA will just let them go ahead with it even for this usage where new tissue is about to be grown in vivo. To me, it just sounds like asking for cancer or some serious trouble later on.
BTW that information about skipping the trials has been here before as well. It’s the same wishful thinking and walking in circles.
What I mean is that you are true, in theory it could happen. History though says that it will not.
