replicel has nothing to speculate about, its a megashot of stemcells that supposedly immunizes the remaining hair on top up to 5 years and regrows some and they are just testing if spreading the dose instead of a big one helps with more regrowth.
Follica so far showed nothing except the claim that it regrows 25 FU's/cm^2, however they said its a complimentary treatment meaning you still need to take finasteride as it possibly does not address the dht part of male pattern baldness. If we knew anything about follica we could probably replicate their results since its science is based on wounding and most people here dermaroll along with minoxidil.
