I’m kinda laughing to myself while reading this thread. When I was a kid my mom used to cut my hair to save money, now back in those days haircuts were only . 25 cents and there were truly bad haircuts, because everyone had the same style haircut which was the standard part on the side, white walls cut and anything different was considered a bad haircut for a kid. So every time she made a mistake she would simply take the clippers and scalp me down to a Vin Diesel shaved head look . Now while that might be the style of today, it was a terrible look for a kid back in those days, and basically told the world that your family was too poor to send their kids to a barber and tried to cut their hair themselves and screwed up.
But today there is no such thing as a bad haircut and from what I’ve seen, anything goes!
