Actor Park Seo-joon revealed a clip showing off his new hairdo on his Instagram account Monday.

In the video, Park unveils the hair transformation -- from messy to well-groomed -- while getting ready for an event. Under the clip he commented “the reason I worked out in the morning.” Earlier in the morning, Park uploaded a photo of the Hangang River just before dawn and still dark, saying he woke up early to exercise.

Park is enjoying the limelight since appearing in two of last year’s most successful dramas -- “Kill Me, Heal Me” and “She Was Pretty.” The 27-year-old is set to star in the upcoming period TV drama “Hwarang,” which will premiere in the summer.
