Your current strategy is a losing one. The hair you shed (if not imagined) was hair that was going to fall out anyway, but your treatments were doing what you want them to do...i.e., having an affect on your hair cycle. Although it seems like a negative one, it's anything but.
The prognosis for your shed hair is a poor one with this type of start/stop panic. You really do have to stick it out...else you might as well get used to your new look.
