Let's be honest for a second. Most of us didn't go into Mission: Impossible – Fallout thinking we’d walk out obsessing over a man’s grooming habits. We went for the HALO jump. We went to see Tom Cruise break his ankle jumping across London rooftops. But then Henry Cavill stepped onto the screen as August Walker, and everything changed. It wasn't just the arms—though, yeah, the arms were massive—it was that specific, rugged, and weirdly disciplined Henry Cavill Mission Impossible haircut that basically reset the bar for how a "tough guy" should look in the 2020s.
It’s a look that managed to feel retro and modern at the exact same time. It’s got that 1940s detective grit mixed with a 21st-century "I will punch through a bathroom wall" energy.
What actually makes the August Walker look work?
If you ask a barber for the Henry Cavill Mission Impossible haircut, they aren’t going to just reach for the buzzers and call it a day. This isn't a simple fade. In fact, it’s remarkably low on the "shaved" side of things compared to the skin fades we see everywhere else. The magic of the August Walker style is in the taper. It’s a classic scissor-cut taper on the sides and back, leaving enough length to show some texture but keeping it tight enough to look military-adjacent.
The top is where the drama happens.
We’re talking about four to five inches of length. It’s a heavy side part, but it’s not slicked down like a 1950s oil tycoon. It has volume. It has movement. When Cavill is reloading his arms in that famous bathroom fight scene, the hair moves, but it doesn't fall apart. That's the hallmark of a great cut. It’s functional.
Most guys make the mistake of thinking they can just grow their hair out and push it to the side. You can't. Cavill’s hair in Fallout relies on weight distribution. The hair is thinned out in specific areas to prevent it from looking like a "helmet," yet it retains enough density to support that iconic swoop. It’s a high-maintenance look masquerading as a low-maintenance one.
The mustache that almost broke the DCEU
We can’t talk about the hair without talking about the "Kingstache."
While the Henry Cavill Mission Impossible haircut is the foundation, the chevron mustache is the load-bearing wall of that entire aesthetic. It’s legendary now, mostly because of the CGI nightmare it caused over at Warner Bros. for the Justice League reshoots. Because Paramount wouldn't let Cavill shave for his Superman duties, we ended up with a digital upper lip that looked like uncanny valley sourdough.

But within the context of Mission: Impossible, that mustache was a stroke of genius. It gave Cavill a heaviness. It made him look less like a "pretty boy" and more like a blunt instrument. If you're planning on mimicking the haircut, you have to consider the facial hair. Without at least some stubble or a heavy mustache, the haircut can lean a bit too "prep school." The grit is required.
Technical breakdown for your barber
Don't just show a blurry screenshot from your phone. If you want the Henry Cavill Mission Impossible haircut, you need to speak the language.
First, tell them you want a classic taper. No skin. You want visible hair all the way down to the nape of the neck. Ask for a "natural finish" on the hairline rather than a blocked-off, squared-back look. This makes the grow-out phase much more forgiving and looks less like you just walked out of a strip-mall franchise.
For the top, specify that you want it disconnected on one side—the side you part it on—but blended on the other. This allows the hair to "roll" over the top of the head, creating that signature August Walker silhouette. If your hair is naturally straight, you’re going to need some "point cutting" to add texture. If it’s wavy like Cavill’s, you’re in luck. The wave is what gives this look its soul.
- Sides: #3 or #4 guard equivalent, but ideally done with shears.
- Top: 4-5 inches, textured.
- Product: Matte pomade or a styling cream. Stay away from gels.
Why this style survived the "trend" cycle
Trends usually die within eighteen months. We saw the "man bun" come and go. We saw the "Permed Mullet" (regrettably) take over TikTok. But the Henry Cavill Mission Impossible haircut has stayed relevant since 2018 because it taps into a timeless masculine archetype.
It’s the "Executive Protection" look.
It screams authority. It’s the kind of haircut that looks equally good in a Tom Ford suit or a muddy tactical vest. That versatility is why guys are still searching for it years after the movie left theaters. It solves the problem of wanting to look professional for work while still having enough "edge" for the weekend.

Managing the "Cavill Curl"
One thing most people overlook is the cowlick. Cavill has a prominent one right at the front of his hairline. Instead of fighting it, his stylist for Fallout used it. They incorporated the natural flip of his hair into the part.
If you have hair that refuses to lay flat, stop fighting it. Use a blow dryer. Seriously. If you want this look, you have to own a blow dryer. Five minutes of heat directed from the roots upward will give you the lift you need. Without the lift, you don't have the August Walker look; you just have a messy side part.
The Reality Check: Hair Density Matters
I hate to be the bearer of bad news, but this cut requires hair.
If you’re thinning significantly at the temples or the crown, the Henry Cavill Mission Impossible haircut might be a struggle. The look relies on "bulk." Because the sides are kept relatively long (tapered, not shaved), you need enough density to create a contrast between the side and the top.
If your hair is on the finer side, you can still pull it off, but you'll need to lean heavily on sea salt sprays and volumizing powders. These products coat the hair shaft and make each strand feel thicker, giving you the structural integrity needed to hold that heavy side-sweep.
How to style it every morning
You wake up. Your hair is a disaster. Here is the move.
Start with damp hair. Apply a small amount of sea salt spray. This provides the "grip" so your hair isn't too slippery. Use a vent brush and a blow dryer to push everything up and back, away from the face. Once it’s mostly dry, find your part. Don't make it too straight—use your fingers for a more "rugged" line.

Take a dime-sized amount of matte clay or pomade. Rub it between your palms until it’s warm and clear. Work it into the roots first, then pull it through the ends. The goal isn't to make it look "greasy." The goal is to make it stay put while you’re running through the streets of Paris (or, you know, walking to the office).
Actionable steps for your next transition
If you're currently rocking a short buzz or a very high fade, you can't jump into the Henry Cavill Mission Impossible haircut tomorrow. You need a transition plan.
Stop cutting the top immediately. Let it get to at least three inches before you worry about the shape. In the meantime, keep your barber focused on tapering the sides. This prevents you from looking like a mushroom while the length catches up.
Once you hit that four-inch mark on top, that's your window. Bring in a high-resolution photo of Cavill from the "bathroom fight" scene—it shows the hair from multiple angles and under harsh lighting, which helps the barber see the texture.
Invest in a high-quality matte clay. Brands like Baxter of California, Hanz de Fuko, or even some of the higher-end apothecary brands work best. You want something with a "firm hold" but a "matte finish." If it shines, it’s wrong. August Walker doesn't do shine. He does grit.
The final piece of the puzzle is maintenance. This isn't a "cut it once and forget it" situation. To keep the taper looking sharp and the top from becoming unruly, you’re looking at a trim every 3 to 4 weeks. It’s a commitment, sure, but for a look this iconic, it’s worth the chair time.
Go find a barber who understands "classic barbering" rather than just "clipping." Tell them you want the Walker taper. Bring the matte clay. And maybe, just maybe, start working on those triceps.
