The detail most barbers miss is that the famous Cillian Murphy haircut is not one fixed style. His Peaky Blinders cut is a severely disconnected crop with exposed sides and a textured top. His Oppenheimer hair is longer, softer and shaped around a natural side part.
Off-screen, Murphy usually wears versatile scissor-cut styles with movement through the fringe. Each version works because the cutting technique supports his fine-to-medium hair, angular jawline and prominent cheekbones.

What Is the Cillian Murphy Haircut Called?
The best-known Cillian Murphy haircut is commonly called the Peaky Blinders undercut, disconnected crop or Tommy Shelby haircut.
However, Peaky Blinders hair and makeup designer Loz Schiavo has made an important technical distinction. She describes the original Peaky cut as a disconnected haircut with a solid outline and heavily textured interior, rather than a conventional undercut.
That difference matters.
A standard undercut usually leaves one long upper section hanging over uniformly short hair. Tommy Shelby’s cut has more internal shaping, deliberate irregularity and a stronger perimeter. The top does not simply sit over the sides like a lid.

The Peaky Blinders Haircut: A Severe Disconnected Crop
The Original Tommy Shelby Shape
Murphy debuted Tommy Shelby’s distinctive haircut when Peaky Blinders began in 2013. The sides and back were clipped extremely short, while substantial length remained through the top and fringe.
There was no smooth transition between those areas. The visible separation created the hard, confrontational silhouette associated with the character.
Schiavo developed the look by combining early twentieth-century references with contemporary male grooming. She also adjusted the design as Tommy’s character matured. The original severe shape became longer and less rigid in later seasons.
Why the Disconnect Changes the Result
A fade gradually moves from short hair into longer hair. A disconnect removes that transition.
This produces three visual effects:
- The exposed sides make the upper section look denser.
- The hard weight line strengthens the head shape.
- The longer fringe draws attention toward the eyes and cheekbones.
On Murphy, the cut exposes his temples and narrow lower face. It also creates width above his cheekbones, which keeps his angular features balanced.
How the Top Is Cut
The top needs controlled texture rather than random thinning.
I would use point cutting through selected sections while preserving weight near the fringe. Removing too much hair with thinning shears can make fine hair appear transparent and weak.
For a practical recreation, keep approximately 50 to 75 mm through the top. Leave the front slightly longer than the crown. These are wearable salon guidelines, not documented measurements of Murphy’s screen haircut.
The fringe should remain heavy enough to sweep across the forehead. A short, feathered fringe changes the cut into a conventional textured crop.
What to Ask Your Barber
Take clear front, side and three-quarter reference photos. Then ask for:
“A high disconnected crop with very short sides, no fade into the top, a solid weight line and a longer textured fringe.”
Specify whether you want the screen-accurate version or a softer modern adaptation.
For the severe version, the sides can be clipped close to the scalp. For greater versatility, retain a little more length and introduce subtle graduation around the temples and occipital bone.
The Softer Peaky Blinders Haircut
The newest Tommy Shelby hairstyle keeps the short-sides, long-top structure but removes much of the earlier harshness.
In recent years, updated versions of the cut have used a subtle blend, relaxed texture and softer movement. A grade 3 or 4 on the back and sides can create a more wearable finish when combined with a textured blend and added length above.
A grade 3 leaves about 10 mm. A grade 4 leaves about 13 mm, although measurements can vary slightly by clipper system.
This version is more suitable for office settings. It also grows out more evenly than the original skin-exposing disconnect.
The severe Peaky cut is no longer the default request in most salons. Softer short back and sides, tapering and natural texture now have broader relevance.
Cillian Murphy’s Oppenheimer Haircut
The Cillian Murphy Oppenheimer hair is not simply a long side part. The film follows J. Robert Oppenheimer across several decades, so Murphy’s length, color, texture and grey coverage change throughout the story.
Christopher Nolan scheduled production around Murphy’s real haircut to reduce the need for wigs.
The Young Oppenheimer Style
For the younger sequences, the hair department used Murphy’s own grown-out hair. The top was permed to create an irregular curl pattern rather than a polished salon wave.
Hair department head Jaime Leigh McIntosh explained that the perm allowed the team to wet and scrunch the hair each day. Temporary airbrushed brunette color covered Murphy’s natural salt-and-pepper tones.
This is why the early style looks convincingly unsettled. The curl is uneven, slightly fluffy and allowed to fall over the forehead.
At home, a small curling iron would make this look too deliberate. A light curl cream, water mist and diffuser provide a more authentic finish for naturally wavy hair.
The Classic Oppenheimer Side Part
In the film’s more formal periods, the hair becomes shorter and more controlled. A defined side part directs the front away from the face without creating excessive height.
The silhouette relies on:
- Scissor-cut sides
- Moderate length through the crown
- A low or natural side part
- Light surface control
- Minimal shine
For a wearable version, keep roughly 60 to 90 mm at the front and 25 to 45 mm through the sides. Ask for a soft taper around the ears rather than a modern skin fade.
Use a vent brush or 25 to 32 mm round brush when blow-drying. Direct the roots sideways and slightly upward. High vertical lift will turn the style into a pompadour.
Cillian Murphy’s Modern Curtain Haircut
Murphy’s awards-season hairstyle offers the easiest version for most men to wear.
Celebrity groomer Gareth Bromell gives Murphy a haircut that can fall naturally in several directions. He scissor-cuts the sides, keeps them fairly short and leaves extra weight through the fringe.
The result sits between a curtain haircut and a grown-out short back and sides.
Why Scissors Work Better Than Clippers
Scissor-cut sides retain softness around the ears and temples. They also allow fine hair to move without exposing too much scalp.
Clippers can create a hard shelf beneath a longer fringe. That contrast is useful for Tommy Shelby, but less effective for Murphy’s relaxed red-carpet styling.
The longer curtain fringe adds width across the forehead. It also frames the cheekbones without hiding the jaw.
How to Style the Curtains
Apply heat protectant to damp hair. Add a small amount of lightweight cream from the mid-lengths to the ends.
Create a loose centre or slightly off-centre part. Blow-dry the front away from the face using your fingers or a 32 mm round brush.
Finish with matte paste or texture spray. Avoid heavy pomade because it can collapse fine hair and separate the fringe into oily strands.
Bromell has also styled Murphy’s hair forward and messy with a heavier fringe. Paste or grooming cream helps retain texture during long red-carpet events.
The Cillian Murphy Textured Crop
A short textured crop is the most practical choice for anyone who likes Murphy’s sharp silhouette but does not want the Peaky disconnect.
Ask for short, softly graduated sides and 40 to 60 mm through the top. Keep the fringe irregular and slightly longer near the centre.
Point cutting creates separation while protecting density. Deep razor cutting is less suitable for very fine or fragile hair because it can produce weak, wispy ends.
Style the crop forward with matte clay. Use no more than a pea-sized amount and warm it fully between your hands.
Hair Color and Grey Blending
Murphy’s hair has appeared dark brown, salt-and-pepper and silver-toned. These changes have included character work and temporary production techniques.
For Oppenheimer, temporary airbrushed color concealed natural grey during younger scenes. Grey was then allowed to appear progressively as the character aged.
Murphy later appeared with a silverish-blond shade connected to his newer Tommy Shelby look. His hairstylist Gareth Bromell confirmed that the color was dyed rather than a sudden natural change.
A salon adaptation should avoid opaque, single-tone permanent color. A demi-permanent gloss or targeted grey blending creates more dimension.
Grey coverage must match the wearer’s skin tone and natural base. Cool charcoal tones can look harsh against warm skin, while overly beige formulas may turn brassy.
Which Face Shapes Suit Cillian Murphy’s Haircuts?
Oval Faces
Most versions work well. Keep enough width at the sides to avoid making the face look overly long.
Square Faces
The Oppenheimer side part and modern curtains soften a strong jaw. Avoid an extremely boxy top with skin-tight sides.
Diamond Faces
Longer fringes balance wide cheekbones and a narrower forehead. Scissor-cut sides are usually more flattering than exposed skin.
Round Faces
Choose a controlled side part or textured crop with moderate height. Avoid a heavy horizontal fringe that visually shortens the face.
Long Faces
The modern curtains are the strongest option. Retain fullness around the temples and keep root lift low.
Suitability by Hair Type and Density
| Hair type | Best version | Technical adjustment |
|---|---|---|
| Fine, straight hair | Modern curtains | Preserve fringe weight and avoid aggressive thinning |
| Medium, straight hair | Peaky crop | Use point cutting for controlled separation |
| Wavy hair | Oppenheimer style | Enhance natural bends with cream and diffused airflow |
| Thick hair | Textured crop | Remove internal bulk without weakening the perimeter |
| Curly hair | Soft Peaky adaptation | Keep extra length and shape curls individually |
| Low-density hair | Side part | Use a soft taper and avoid exposed scalp at the sides |
The original Peaky cut can exaggerate recession at the temples. A softer blend or forward fringe is safer when the hairline has changed.
Styling and Maintenance
The severe Peaky cut needs attention every two weeks. The exposed sides quickly lose their graphic shape.
The softer crop can last three to four weeks. Curtains may stretch to five or six weeks if the outline remains clean.
Daily styling should take five to ten minutes:
- Apply heat protectant to damp hair.
- Direct the fringe into position while blow-drying.
- Add matte paste, cream or clay.
- Separate selected sections with your fingertips.
- Finish with flexible hold spray when needed.
Keep dryer heat at a moderate setting. Fine hair can become brittle when repeatedly exposed to concentrated high heat.
Clarify once weekly when using wax or clay. Product buildup reduces movement and makes the roots appear flatter.
Frequently Asked Questions
What is Cillian Murphy’s haircut called?
Cillian Murphy’s best-known haircut is called the Tommy Shelby haircut or Peaky Blinders undercut. Its designer describes it more precisely as a disconnected haircut with a solid outline, very short sides and a heavily textured interior.
How do I get Cillian Murphy’s haircut?
Choose the specific version first. Ask for a high disconnected crop for Tommy Shelby, a scissor-cut side part for Oppenheimer, or short sides with a long curtain fringe for Murphy’s modern red-carpet style. Bring several reference photographs.
Is the Peaky Blinders haircut an undercut?
It is commonly labelled an undercut, but hair designer Loz Schiavo disputes that technical description. Her original design uses a solid outline, textured interior and deliberate disconnection rather than the standard structure of a conventional undercut.
What product does Cillian Murphy use in his hair?
Groomer Gareth Bromell has used matte texturizer, grooming cream and texture spray on Murphy. The correct product depends on density. Fine hair needs lightweight cream or spray, while thick hair can support matte paste or clay.
Does the Cillian Murphy haircut work with receding hair?
The Oppenheimer side part and modern curtain style can work with mild recession when the fringe retains density. The severe Peaky cut exposes the temples, so it may emphasize recession rather than conceal it.
Is the Cillian Murphy haircut still fashionable?
Yes, but the most relevant version is now softer. Modern salons favor natural texture, scissor-cut sides and subtle blending. The original high disconnect remains recognizable, while the updated shape is easier to maintain and wear.
