The Serrated Bob Is Destined to Be 2026's Coolest Haircut—Here's How to Wear It

It's been a while since I've written about a bob hair trend. Whilst the bob hairstyle has been one of the most popular short haircuts of the year, it seems that people have been favouring longer lengths on the run-up to winter. However, now that the new year is on the horizon, I've spoken to many people who are considering getting the chop once again, and I'm telling all of them to try the serrated bob haircut. This newer bob trend is the ultimate cool-girl take on the classic bob haircut, which has been around for a while.

I spoke with BaByliss ambassador and hair stylist to the stars, Syd Hayes, about how to achieve the look, so keep on scrolling for everything I want you to know.

What Is a Serrated Bob?

"The serrated bob is a modern, cooler evolution of the classic bob," explains Hayes. " start with a clean outline, then use a razor to break up the perimeter, giving the ends that feathered, dishevelled finish—light, airy and completely effortless. It’s the kind of texture that moves beautifully on camera and never feels overworked."

The best thing? Hayes says this style can work for all hair types. It will help straighter hair to gain movement and softness, whilst wavy hair will fall into a naturally undone texture. "With light razor use, the perimeter becomes soft on curly hair, and internal feathering removes bulk while keeping the shape buoyant on thick hair," Hayes tells me. When it comes to fine hair, he says that it will need delicate serration to add body without making the ends too thin.
