Update (advice needed)

I posted in this subreddit a little while ago and the amount of feedback I got was so appreciated. My blood tests and stuff came back with some vitamin deficiencies but other than that, I seem to be doing okay. It's just a waiting game now but I'm stuck and need advice.

The rate at which my hair is falling out is so much to keep up with, multiple hair brushes every time I brush my hair. I just don't know if I should bite the bullet and shave the rest or just let it run its course?
