That's Replicel and HairClone's strategy. Tissuse doesn't require a follicle. The consensus in research is that at a certain point the follicle is dead. Hence the need for Follica to recruit cells to create a new DP.
Oh ok, wasn't sure. Just remember reading something about TissUse hoping to "revitalize" already existing follicles in addition to the newly created follicles. But yeah, that doesn't make much sense anyway...no need to revitalize old follicles if the main objective is to create enough new follicles to produce a satisfactory look.
