Park Seo Joon plays entrepreneur Park Sae Ro in Itaewon Class, a series based on a webtoon with the same name. He cut his beautiful swoon-worthy hair (the one we all loved in What's Wrong With Secretary Kim?) to a bowl cut to bring his character to life. (You can watch his hair transformation here!)
In a press conference for Itaewon Class, Seo Joon talked more about his high maintenance haircut—he said that he has to have it cut every four days. That's a lot of commitment! "I’ve been maintaining this hairstyle for six months. Cutting my hair every four days," he confessed. Honestly, Seo Joon makes our woes with bangs upkeep seem petty.
So, if you're guy is eyeing on sporting a bowl cut like his, Seo Joon advised not to do so. "I thought that people wouldn’t copy this hairstyle, but many people are doing it. I heard that some hairstylists are having a hard time. It takes a lot more maintenance than it looks. I recommend that you don’t do it," he warned.
His friend, Park Hyung Sik, left the funniest comment on one of his posts to describe PSJ's unique haircut. He wrote: "Shiny chestnut." (Now I can't unsee my mental image of PSJ as a chestnut.)

You can watch Itaewon Class on Netflix.
