Fact: There are more bobs in the world than there are oat milk brands in East London. Bob from HR, Bob the builder, Bob Ross, and of course, the hundreds of bob haircuts. We've dissected what defines the Italian bob, the geometric bob and the heart-throb bob, but today, we're tapping the minds of hairstylist and trend forecaster, Tom Smith, to really understand what makes the 'bottleneck bob'.
One of the many bobs, yes, but the bottleneck style is one that's not only got a flair for the dramatic but is flattering on almost everybody! More on who it's best suited to, below, as well as how to style the cut and inspo pics galore...
Like I said, the possibilities bobs are endless!

What is the bottleneck bob?
The bottleneck bob is elusive in name, so Tom explains more about what defines the style. "It's a hybrid haircut that extends the soft, face-framing fringe of a bottleneck bang into a textured, ruffled mid-length bob shape," he says. The top of the head starts with the bottleneck shape, narrow and shorter between the brows, curving out and around, and finally kicking out from the cheeks to the chin.
Think of it as a step towards the shape of a shag haircut, but more wearable. "It's modern, flattering, and more versatile," Tom adds.

Who is the bottleneck bob best suited to?
Not everyone is going to think they're suited to a short bob haircut – it can be scary territory for the long-haired girls! That said, Tom says, "This cut is particularly flattering on oval, heart, and longer face shapes because the fringe narrows the forehead and the length balances the jawline." Noted.
"Very round face shapes," on the other hand, "may find the face-framing layers emphasise roundness unless the bob is left slightly longer and styled more with a side parting," he adds. After all, when it comes to haircuts, it's all about finding facial harmony and working out what suits you best!
In terms of hair type and texture, Tom says the weight of the cut makes it super versatile. "The bottleneck bob works beautifully on medium to thick hair textures, as the fringe and shaping help distribute weight, but it can also help to add the look of fullness in hair that is finer or flatter."
However, those with very curly or coily textures may want to be cautious when it comes to this hairstyle; "It can turn more into a rounded shag shape, and you may find smoothing it out too much maintenance – unless they have the time and interest in daily heat work," Tom says.
How to style the bottleneck bob
To get the best out of your bottleneck bob, Tom reminds us that it's all about the texture. "Styling should enhance the undone, effortless quality of the cut," he says. "A round brush or a wide barrel tong can add soft bends through the lengths, while a texture spray will give it that modern, airy feel. The fringe should skim the brows and cheekbones, creating softness rather than any blunt edges."
