Every woman needs an easy updo hairstyle she can count on in a pinch. One that’s created without much fuss, can be thrown together on the fly, and serves as a faithful go-to option when parties come a knockin’. This may explain why the purposely messy bun that’s dominated runways and red carpets for the past few years continues to gain steam. “It’s been a big hit on and off the runways,” says celebrity hair and makeup artist Tony Masciangelo. “Obviously there’s the fact that it’s easy to create on your own, but I think another reason stylists and women love the messy bun is because it shows people that beauty doesn’t have to be perfect.”
