Seems new trials are on the way, this is good.
@Fox243 Dr Barghouthi and Dr Mohebi will have new trials. I think that will be enough evidence already for Standard FUE. IMO it's better to direct efforts towards more scenarios that hasn't been tested. Like injuring recipient and injecting verteporfin, Revising old FUE scars.
Also there are big pockets with hair loss or unsuccessful HT, with enough evidence they will back up more trials, worth to contact them.
