I did get a haircut but it was outside on the patio (we have a friend who lives a few blocks away who is a hairdresser). I set up a folding chair and came back out with my hair wet. We both wore masks and she had a face shield too. She left right after and I venmo'd her money. Nobody got covid (no symptoms and I had an antibody test a few weeks later that was negative).
FWIW, DW got her hair cut and dyed in a salon (also masked) and didn't get covid either.
