Softer edges, a deep side part and a wave that looks like it happened on its own. The classic French bob is all about precision: a blunt line at the jaw, maybe bangs, nothing out of place. It is chic, but it can also feel a little strict, and it needs constant trims to keep that sharp edge. Keira Knightley just showed a gentler way to wear it.
Celebrating her West End comeback in The Lives of Others, the actress, 41, debuted a new cut at the press night after-party at Brasserie Zédel in London on October 29. Her hairstylist, Luke Hersheson, founder of the Hershesons salons, blended the chin-skimming length of a French bob with the soft, cascading layers of a waterfall bob, set off by a deep side part. According to Hersheson, the look “stays true to Knightley’s personal style which has always been a little more offbeat and cool.”
What Makes It a ‘Waterfall’ Bob
A waterfall bob uses long, soft layers that seem to tumble down from the crown toward the face, instead of one solid line. Combined with a French bob’s short length, it keeps the shape compact but adds movement. The deep side part is key: it sends more hair to one side, creating a natural sweep that frames the face and makes the layers fall like water.
The result looks effortless, slightly undone and much easier to live with than a razor-sharp bob.
The Styling Trick Behind the Wave
The texture is not a classic curl. “I used my multi-tasker mermaid waver attachment which has large barrels,” Hersheson explained. “It gives a really subtle flat wave.” To finish, he added a light spray for separation and hold, so the layers stay piecey instead of fluffy.
A flat wave suits short hair particularly well. Round curls can make a bob look shorter and fuller, while a flatter wave keeps the length and adds texture. It is the kind of easy cut that works at any age, much like the short haircuts that make silver strands look chic.
How to Ask for It at the Salon
Ask for a chin-length French bob with long, soft layers rather than a blunt line, and show a photo with a deep side part. Ask your stylist to keep the ends slightly textured so they move. At home, use a large-barrel waver or a flat iron with a gentle twist to create flat, loose waves, working in sections and skipping the very ends. Finish with a light texture or air-dry spray, scrunch with your fingers and avoid brushing it out. Keep the side part deep for the most flattering sweep. If your hair is very fine, ask for fewer layers so the bob keeps its body.
Pair the cut with an equally relaxed beauty look, such as the glossy onyx nails Olivia Colman made this autumn’s most elegant manicure. The lesson worth borrowing is that a bob looks more modern when it moves.
The Bottom Line
Goodbye, sharp bob: Keira Knightley, 41, debuted a soft “waterfall” French bob for her West End comeback, with a deep side part and a subtle flat wave. It is a softer, easier take on a classic, and it suits almost any hair type.
