I don't know about a woman cutting her hair, but I wore a beard for years. As time went by, I got more and more of an inclination to shave it. Finally, I did, but only down to a goatee. I kept that for a few years more and then finally ditched it, too. Both times, I reappeared to provide a shock to my wife. However, it didn't bother me at all. Of course, I was bending to my own growing notion, not an exigent event.
