But this is one of your stated reason why you don't like the idea of getting hair transplants to get more coverage coupled with Replicel to protect it. And now you agree that the same problem would potentially exist with Follica, Tsuji, Kemp, and Terskykh.
No matter which of these treatments is used, for people with some thinning in their donor area the best solution is to cryo-preserve cells. They'll have to thaw some and inject them more frequently than people who have better donor areas but at least they'll have a solution.
For the same reasons that cryo-preserved cells might protect from future losses if you get Follica, Tsuji, Kemp, or Terskykh treatments; cryo-preserved cells could also protect from future losses if you get a hair transplant coupled with Replicel.
Yea, the cryo-preserved donor area cells of people with somewhat thinning donor areas wont be as good as the cells of a 16-year old's donor area, but the same can be said of those same cells when they're used to create hair germs (or whatever) for Follica, Kemp, Terskykh, or Tsuji treatments.
