Trends come and go . . . and some come right back again. That’s exactly what’s happened with this ’90s-esque ‘do, the half-up half-down bun. Some call it the “hun.” Others don’t know what to call it. They just know they’re seeing it everywhere. The hairstyle has taken the streets and the Pinterest feeds of America by storm. But don’t think it’s stuck in the ’90s doldrums. Even though it’s a throwback, the look is getting a fresh, 21st-century update with funky color, natural textures, and bling-infused accessories. So just a heads-up that you might want to get used to this one—everyone who tries out the half-up bun becomes a cheerleader for its easy, cool vibe.
