I am interested in anything that can immunize hairs long term or better still permanently. Reason being I still have a lot of hair left which I hope to keep while waiting for Tsuji.
The only treatment giving a glimmer of possibility for immunization is Replicel/Shiseido. Personally, I don't trust Replicel, however I hope Shiseido scientists know more and can make this process work somehow, maybe by tweaking it or adding some other elements. We should know in the next 2 years how that pans out.
I'm also interested in Follica for de novo regrowth. I group Follica within the "regrowth" category of treatments along with Tsuji. It would be wonderful if one day we had the choice between new cloned hairs or wounding hairs.
It would be the ultimate goal to get de novo regrowth from Follica or Tsuji, but to fully arrest the balding process you need to immunize what's left. That's where I hope Shiseido can conjure up something unique.
I don't care if Shiseido dont regrow anything, as long as they can permanently immunize the hairs they will have done their job in preparation for Tsuji.
