Until last month, I hadn't gotten a paid haircut since the start of the pandemic. Got a decent pair of clippers with a taper guard, and did "okay" except for the edging on the back, which I learned to just not worry about (though my wife has done it a couple of times, and it comes out decent then)

If you have a baseball cap you can hold the brim (pointed down!) against the back of your neck and trim along it for something half decent :)

Great tip - I'll have to try that

It would be easier if we could reject bad hair pull requests.

You can consider the last two years to be a staging environment, depending on your industry.
