Let’s be real for a second. If you close your eyes and think of Diane Keaton, you probably see a high-neck turtleneck, a massive belt, and a hat that could double as a satellite dish. But the real magic? It’s what’s happening underneath the brim. The hairstyles of Diane Keaton have basically rewritten the rulebook on how to look effortlessly cool while your birth certificate starts to look like a vintage artifact.
Honestly, she’s the queen of the "I just rolled out of bed but I also own the building" aesthetic. For decades, we’ve watched her transition from the long, brunette waves of the 1970s to the sharp, silver-streaked bobs of 2026. She doesn’t do "done" hair. You won’t see her with a stiff, hairsprayed helmet. Instead, it’s all about texture, movement, and a refusal to fight against the natural flow of her hair.
The Annie Hall Era: Brown Waves and "No-Style" Style
In the late '70s, specifically around 1977, the world fell in love with a neurotic, tie-wearing woman named Annie Hall. That was Keaton. Back then, her hair was a soft, medium-to-dark brown. It wasn't overly styled. Basically, it was long, slightly wavy, and usually tucked under a black bowler hat or a fedora.
What’s wild is that she actually hated her hair back then. She’s gone on record in her 2024 book Fashion First saying she wore hats because she hated the "strange area from your eyebrows to your hairline." Talk about relatable. But while she was busy hiding, she accidentally created the blueprint for the "anti-style" movement. It was messy. It was real. It was the exact opposite of the hyper-groomed Farrah Fawcett curls that were everywhere else.
The Blonde Pivot and the 90s Bob
By the time the mid-90s hit—think Amelia Earhart: The Final Flight in 1994—Keaton took a hard left turn into platinum blonde territory. She chopped it into a short, almost architectural bob. It was a massive departure. This wasn't just a color change; it was a shift in energy.
- The 1994 Chop: A short, sleek platinum look that felt very "New York Executive."
- The 2000s Highlight Era: Around the time of Something's Gotta Give, she moved into a light brown/blonde mix with lots of face-framing layers.
- The Texture Shift: She started moving away from the flat-ironed look and toward the "shaggy" texture we know today.
She’s mentioned before that she felt the blonde was a bit high-maintenance. You’ve probably felt that too—the constant battle with roots is a full-time job.
Moving to Silver: The Gray Hair Revolution
Around 2014, Diane did something that felt like a radical act in Hollywood: she stopped dyeing her hair. She let the silver grow in. But here’s the thing—she didn’t just let it go "flat." If you look closely at her hair at the Golden Globes or her recent 2025 appearances, it’s not just one shade of gray. It’s a masterclass in dimension.
Her stylist (shoutout to the pros like Rogerio Cavalcante who often analyze her look) uses a technique called "lowlighting." Instead of trying to cover the gray, they add darker streaks to create depth. This is why her hair never looks "old" or "washed out." It looks intentional. It looks like a choice, not a surrender.
How to Get the "Keaton Bob" (Without Looking Like a Costume)
If you want to copy her current look, you need to ask for a "shaggy long bob" or a "lob." But there are some specific technical things your stylist needs to do.
The secret is point cutting. Instead of cutting the hair straight across (which makes it look like a mushroom), the stylist snips into the ends at an angle. This creates that "messy flick" that Diane is famous for. It gives the hair height at the crown, which is vital as hair tends to thin out or lose its "oomph" as we age.

- Ask for: A shoulder-length bob with interior layers.
- The Fringe: Ask for "piecey" bangs that hit right at the eyebrow.
- The Products: You’ll need a styling paste or a matte pomade. You basically just rub a dime-sized amount between your palms and "scrunch" the ends.
Why the Shaggy Bob Works for Everyone
The reason the hairstyles of Diane Keaton are so enduring is because they focus on frame. She knows she has a long-ish face and striking glasses. By keeping the length around the jaw and adding volume at the sides, she balances her features.
Also, can we talk about the hats again? She uses them as an accessory, not a crutch. If you’re having a bad hair day, a wide-brimmed hat over a messy bob is an instant "look." It’s sort of her armor. She told AARP years ago that she was trying to wear hats less, but let’s be honest—we hope she never stops.
Actionable Steps for Your Next Salon Visit
Ready to go full Keaton? Don't just show up and say "Make me look like Diane." That's how you end up with a haircut that doesn't fit your face.
First, look at your hair's natural texture. If your hair is bone-straight, you're going to need a sea salt spray to get that "gritty" Keaton vibe. If it's curly, you'll need a smoothing cream to keep the bob from turning into a triangle.
Next, consider the "Silver Transition." If you're tired of the dye cycle, ask your colorist about "gray blending." This involves using fine highlights and lowlights to bridge the gap between your natural gray and your old color. It’s the exact route Diane took, and it’s way less painful than the "harsh line" grow-out phase.
Keep your layers moving. Use a light mousse at the roots for lift. And most importantly, as Diane herself once said, "Just have fun. Smile. And keep putting on lipstick." The hair is just the frame; you’re the picture.

Invest in a high-quality purple shampoo to keep those silver tones from turning yellow. This is the single most important maintenance step for anyone rocking a natural gray bob in 2026. Try something like the Oribe Silverati or even a classic drugstore option—just make sure it's used once a week to keep the "icy" look Diane nails every single time.
