Hair Affair: The Most Popular Styles of the Last Century

19. The Karen

Social media sites like Instagram, TikTok, and YouTube were behind major 2010 hair trends, like the curly girl movement and rainbow hair fad. But they also—unintentionally—popularized another prominent hairstyle from the decade. Known as the Karen, this cut features a wedged back cut in chunky layers with a longer front that falls in angled pieces along the jawline. Hairdressers know it as an inverted bob or A-line cut.

Reality star Kate Gosselin originally popularized the look on her show John & Kate Plus 8 in the late 2000s. But the style isn't one of the most recognizable of the decade because of Kate Gosselin. Thanks to viral videos of women with a similar haircut harassing store employees and people of color in public, the wedge cut that Gosselin's fans loved became synonymous with whiny, entitled women in the 2010s.
