It's been a long time since I got a bad haircut, but there have been four I can recall. Right now, I look like like a Pomeranian dog with a beard. This is going to take a while to clear up. I laugh every time I look in the mirror. Others are being polite.
The most noteworthy haircut I had was when the barber took way too much off the top and I had what was nearly a bald spot. That took a while to clear up.
The other two were at a chain called Great Clips, where they don't really employ barbers. They employ relatively unskilled people. Never again.
