I'm also in a law firm but I'm in our Finance Dept. We're normally business casual. I usually keep my head shaved and a goatee (salt & pepper).

When they told us to work from home in early March, I decided to let everything go until we go back to the office. I assumed that this would be maybe 2-3 months at most. Here we are in October and they've told us that we won't be back in the office anytime before January.

My hair is out of control. One interesting thing I've noticed is that my face is ravaged by white hairs. But not so much on my head. Maybe 5 or 6 stray ones up there.

I'm considering giving in and cutting it all off though. It's starting to get on my nerves.
