I had very bad hair loss last summer after a bad flare and pred taper. The whole top of my head was sore for at least three months. I took Biotin to make my hair stronger (still taking it now). My hair did stop falling out, but only after I cut down my dosage of Asacol, which I had upped for the flare as well. I assumed it was from the Asacol and not the pred side effects, but no one seems to know for sure. It will get better, though.
