Men in North Korea are now required to get the same haircut as their leader Kim Jong Un, it is reported.

The state-sanctioned guideline was introduced in the capital Pyongyang about two weeks ago, according to Radio Free Asia.

State-sanctioned guidelines were reportedly imposed on the capital Pyongyang two weeks ago, the BBC reports, with the shaved sides, ahead-of-the-trend, high-top fade haircut look now being rolled out across the country.

But some people have expressed reservations about getting the look.

"Our leader's haircut is very particular, if you will," one source tells Radio Free Asia.

"It doesn't always go with everyone since everyone has different face and head shapes."

Meanwhile, a North Korean now living in China says the look is actually unpopular at home because people think it resembles Chinese smugglers, BBC reported.

"Until the mid-2000s, we called it the 'Chinese smuggler haircut'," the Korea Times reported.

It is believed that haircuts have been state-approved in North Korea for some time - until now people were reportedly only allowed to choose from 18 styles for women and 10 for men.

Earlier, North Korea's state TV launched a campaign against long hair, called "Let us trim our hair in accordance with the Socialist lifestyle".
