How will Replicel or Aderans technique be used?

[BoSox]

Forgive me if this has already been discussed.

..but let's say Aderans or Replicel's technique works. Will this ONLY be used as a "filler" type of treatment while traditional hair transplants are still needed?

The illustration on Replicel's site obviously indicates a NW7 restored to NW 1/2, but how exactly will these procedures achieve this and is it possible with just injections alone?

Cheers.
