Default fish disease?

I have a yellow tailed blue damsel that appears to have lost all of
the blue coloring (scales?) at the top of his head and around his
eyes. So he's mostly blue, but black in that area.

Electrical leakage into the tank can cause this sort of thing. If all your
submerged equipment is on a GFCI outlet, this is almost certainly not the cause.
If you don't have a GFCI, get one. If it trips, unplug equipment and reset until
it doesn't trip. Replace the last item you unplugged.

If this is the cause, the scales may not regrow, but the fish will be ok.
