1990s’ “5-5 Part” Trend Revives Globally... K-Pop Stars Redefining Global Beauty Standards

The iconic 1990s hairstyle known as the “5-5 part” is making a comeback, particularly in the United States. Popular celebrities such as actor Charles Melton and comedian John Mulaney have adopted this style, drawing significant attention. It is evolving beyond mere retro appeal to become a new cultural movement. This trend revival is driven by K-Pop, . Global stars like BTS, SEVENTEEN, and EXO have reinterpreted 1990s-style parts on stage, causing their fans around the world to perceive it as a “cool” look. What was once considered outdated has been completely transformed into a sophisticated retro style through its association with K-Pop idols. This hairstyle trend does not limit itself to haircuts alone. In fashion, 1990s styles such as wide pants, oversized jackets, and loafers are resurfacing, while in music, tracks that modernize classic sounds like lo-fi and synth-pop are gaining popularity. The beauty industry is also seeing a resurgence in retro makeup that evokes nostalgia. Although retro trends repeat periodically, this time they differ from past cycles because Korean popular culture is giving them global traction. As K-Pop content spreads and its stars become cultural icons, South Korea’s approaches to hair and fashion are serving as benchmarks for world popular culture. Styles commonly adopted by K-Pop stars—such as the 5-5 part, dandy cut, and two-block style—have now become symbols of style worldwide beyond Asia. Icons representing alternative fashion styles include Hikaru of Kep1er (a blend of grunge, punk, and cuteness), Chaeyoung of TWICE (a cool girl aesthetic), Rei of IVE (Y2K-style cuteness), Jeon Soyeon of (G)I-DLE (a restrained alternative style), Choi Ye Na (aesthetic flexibility), Jennie of BLACKPINK (a confident style), and Hongjoong of ATEEZ (a masculine alternative style). Once focused on catching up with European and American styles, South Korea’s fashion and beauty industries are now leading the world. This is a clear example of how K-Pop’s influence extends beyond music to affect overall lifestyles and styles.
