The M&M Hair Academy posted Jong Un's picture accompanied by the phrase, "Bad Hair Day?"
“We put up posters for an offer for men's hair cuts through the month of April. Obviously in the current news there has been this story that North Korean men are only allowed one haircut,” barber Karim Nabbach told the BBC.
After embassy officials contacted the police, they paid a brief visit to the salon before being asked by the manager to leave.
"We didn't realize but the North Korean embassy is a 10-minute walk from the salon. The next day we had North Korean officials pop into the salon asking to speak to the manager,” Nabbach said. "He said 'listen this isn't North Korea, this is England, we live in a democracy so I'm afraid you're going to have to get out of my salon.'"
Nabbach, 26, came up with the poster, which offers 15 percent off men’s haircuts. Despite the large ad, he hasn’t had too many people coming in to request Jong Un’s hairdo.
“We have never had to perform that haircut on anyone,” Nabbach told the Guardian. "Perhaps, if David Beckham wore it. But, I don't really see it catching on to be honest."
