People doubt RepliCel because the results of their phase I trial were underwhelming, to put it lightly, and they only followed progress for six months. I can't find anything about 5 years anywhere.
It's going to take some damn impressive results, with plenty of follow up, from phase II for me to regain confidence in RepliCel.
The smart money's on Tsuji and the funky bunch at this point.
imho we're comparing apples and bananas here.
Afaik, Replicel is mostly for maintenance (like current meds -- hopefully better and with no sides), Tsuji is for regrowth (like current transplants).
The one does not exclude the other, and both the market and individuals need both (e.g. you can tsuji your bald spots, but will still lose native hair if you don't replicel it).
It depends very much on where you're sitting: something to save still? Reached the bottom of it?
For the same reason, I'm not expecting stellar results from Replicel pics: maintenance is not spectacular.
But: if treating an area of my scalp with replicel means saving that hair for good, or for a long time... well, that's spectacular to me.
