Hi alli,
I've had the hair loss and itchy scalp for a couple of months. My med experience is not the same as yours, though. I'm trying to reduce the number of asacol I'm taking and switching to rowasa. Quincy asked some good questions that I hope will help me make a gradual med switch.
Are you washing your hair the same as before or less frequently because you're afraid to see the hair loss? That could effect the itchiness, especially if you're not washing it as often. Also, you may be growing hair more rapidly and the new little hairs could be contributing to the itch. Last, if you're on any form of prednisone, that can contribute to hair loss.
Good luck!
