Everything I've read says no, but I was put on potassium supplements after blood test revealed low potassium and my hair loss stopped that week. I went to clean out the hair trap in my shower for several days in a row and the trap, normally clogged with my hair, was clean! Having a normal potassium level is the only thing in my lifestyle that changed.
So, and this is just my own experience, yes it can cause hair loss.
