In a city known for its timeless style and sharp silhouettes, the Slick Back with Undercut has become a front-runner for modern gentlemen in 2025. This is more than just a haircut—it’s a power move. Combining vintage elegance with urban grit, this style captures the best of both worlds: tailored polish with confident attitude.
It’s seen on creatives in Shoreditch, executives in Mayfair, and entrepreneurs in Soho. Whether you’re behind the boardroom table or leading your own brand, the slick back with undercut says: I’ve arrived—and I’ve got my look together.
Let’s break down how this style works, how to know if it suits you, and how to maintain it with help from your independent barber and a select few premium products from Pall Mall Barbers London.
What Is the Slick Back with Undercut?
The Slick Back with Undercut is where elegance meets edge—a haircut that perfectly balances structure and flow. Originating in the 1920s and revived in the post-war ‘40s, the slick back earned its legacy as a go-to for gents who wanted to look well put-together without being overly styled. Fast forward to today, and it’s taken on a bold, urban twist: enter the undercut.
This modern variation features closely clipped or shaved sides and back, typically done with clippers or a tight fade. What makes it distinct is the disconnection—the undercut is left separate from the longer hair on top, creating a striking contrast that immediately sharpens your profile. On top, the hair is grown to medium length—usually 4 to 6 inches—long enough to be swept or combed straight back with a product of your choice.
The result? A style that’s:
-
Timeless yet forward-thinking
-
Sleek yet strong
-
Minimal at the sides, maximum impact up top
This haircut doesn’t hide in the background—it commands attention. You’ll often see it paired with a sharp suit, a well-fitted overcoat, or even a leather jacket. It’s adaptable, bold, and makes an impression from boardroom to rooftop. What really makes this cut special is its versatility. You can style the top:
-
Glossy and clean for business meetings or formal events
-
Looser and textured for a more relaxed, fashion-forward appearance
-
Pulled into a mini-pomp or even man-bun if your hair’s long enough
It’s also a top pick for gents growing their hair out. The clean undercut gives structure and shape during awkward in-between lengths, making the grow-out process intentional—not unkempt. Ultimately, the slick back with undercut is for the man who likes his grooming to match his mindset: focused, refined, and never afraid to make a statement.
Is This Your Style? Who Does It Suit Best?
The slick back with undercut isn’t just a style—it’s a declaration. It’s perfect for men who appreciate structure, sharpness, and the power of presence. If your hair is medium to thick in density and tends to grow straight or with a subtle wave, this cut will work with your natural texture—not against it. It gives you the flexibility to style with ease while delivering a strong, defined silhouette every time you walk out the door.
This look suits gentlemen who like to make their style decisions feel intentional. If you’re someone who doesn’t just wake up and go—but rather, prepares to show up sharp and sure of yourself—this haircut mirrors that mindset. It’s ideal for men who thrive in high-stakes environments or fast-paced cities like London, where a well-groomed appearance signals readiness, attention to detail, and drive.
Facially, the slick back with undercut works best on men with square, oval, or angular face shapes. These strong foundations complement the haircut’s bold lines and clean structure. That said, even softer face shapes can wear it well when paired with a well-trimmed beard or fade blend that adds contrast.
If you naturally push your hair back, or you’re constantly adjusting your fringe to stay out of your face, this style is a seamless fit. And if you gravitate toward sharp tailoring, double-breasted blazers, elevated streetwear, or minimalist grooming routines, the slick back with undercut becomes an extension of your style language—refined, smart, and always ahead of the curve.
So, if you’re the kind of gent who values impact over trend and wants a cut that says “I’ve got this” without having to explain it—this is your signature look.
Your Barber’s Role: Precision + Customization
This is a cut that demands technical accuracy. Your independent barber will:
-
Use clippers or scissors to create a clean undercut—either skin-faded or slightly tapered, depending on your desired contrast.
-
Blend or disconnect the top cleanly to avoid bulk or uneven transition.
-
Shape the top for your natural hair flow, adding a slight layering to prevent puffiness.
Pro tip: Ask your barber to taper the nape and refine your hairline—it adds polish and makes styling at home significantly easier.
Frequently Asked Questions: Slick Back with Undercut
Can I wear the slick back with a beard?
Absolutely. The slick back pairs perfectly with a short, boxed beard or a full, groomed beard. Just make sure your beard is shaped and defined to match the clean aesthetic of the haircut.
What if I have wavy or curly hair?
This style works well with slightly wavy hair—in fact, it adds volume and movement. If your hair is tightly curled, you may need a texturizing cut and a stronger hold product like Pompadour Paste to control it.
How often do I need to visit my barber to maintain this look?
Every 3–4 weeks is ideal to keep the undercut sharp and the length on top tidy. A shape-up or taper at the nape between full cuts helps the style stay fresh.
Can I wear this look casually?
Yes—just use less product and air-dry the top. You’ll get a more relaxed, textured version of the slick back that still looks put-together. Sea Salt Spray alone works wonders on weekends.
