No, it was a rough number not based on speculation but on a fictional duration of miniaturisation. If the original process for you to get from NW1 to NW4 took 10 years, then it will be 10 years again after treatment. Of course, if you started balding at 17 and were NW4 at 19, then it will take two years post-RCH-01 treatment as well and then the treatment will likely not be a sensible option.No one knows if you need to redo the treatment after 2 years or 10, pure speculation
