The Iconic Tommy Shelby Undercut

Perhaps one of the most talked-about Cillian Murphy hairstyles is the one he wears as Tommy Shelby in *Peaky Blinders*. This look is a very distinct undercut, where the sides and back of the head are cut extremely short, almost shaved, while the hair on top is left much longer. It's a style that really became popular because of the show, and it perfectly fits the character's tough, sharp persona, you know?

This haircut has a rather rebellious feel to it, which was very much in style for working-class men in post-World War I Britain. It was practical for fighting, as hair couldn't be grabbed easily, but it also became a powerful fashion statement. For Tommy Shelby, it signifies his control and his status, so it's more than just a haircut, really.

The contrast between the short sides and the longer top creates a very striking silhouette. It's a bold choice, and it certainly makes an impact. Many people have tried to copy this look, which shows just how influential it has been, and it's still quite popular today, apparently.

Getting the Shelby Look

If you are thinking about getting a haircut like Tommy Shelby's, you will need to ask your barber for a disconnected undercut. This means there is no fade between the very short sides and the longer hair on top; it's a clear, sharp line. The sides and back should be cut with clippers, often down to a very short grade, like a number one or even a zero, depending on how bold you want to go, typically.

The hair on top needs to be left long enough to style. For Tommy Shelby, it's usually swept back or parted to the side, with some volume. The length on top can vary, but generally, it should be at least a few inches so you have something to work with. This allows for versatility in styling, which is good, you know?

When you are talking to your barber, bringing a picture of Cillian Murphy as Tommy Shelby is probably the best way to make sure you both are on the same page. This helps them understand exactly the kind of cut you are looking for, so there's no misunderstanding, which is quite helpful, actually.

Maintaining the Undercut

Keeping the Tommy Shelby undercut looking sharp requires fairly regular visits to the barber. The short sides grow out quickly, so you will need to get them trimmed every two to three weeks to maintain that clean, disconnected line. This is pretty much essential for the look to stay crisp, honestly.

For styling the top, you will want to use a product that offers good hold but also allows for some movement. A pomade or a strong-hold cream works well. Apply it to damp or dry hair, then comb or brush the top back or to the side, creating the desired shape. You might even use a bit of hairspray to keep everything in place, especially if you want it to last all day, so that's something to think about.

This style, you know, needs a bit of effort to keep it looking good. But for many, the distinct and rather confident appearance it gives is totally worth the time. It's a statement, after all, and it really shows off your features.

The Longer, More Relaxed Styles

Beyond the sharp lines of the Shelby undercut, Cillian Murphy has also worn longer, more relaxed hairstyles throughout his career. These looks often highlight his natural hair texture and give him a somewhat softer, more artistic appearance. Think about his earlier roles, like in *28 Days Later*, where his hair had a bit more length and a natural, slightly messy flow, so it was a different vibe entirely.

These longer styles often involve hair that falls around the ears or even touches the collar, sometimes with a natural wave or curl. They convey a sense of ease and a less structured approach to grooming. It’s a contrast to the very precise cuts and shows his versatility, which is really something, you know?

This kind of look can be very appealing for those who prefer a less formal hairstyle or whose hair naturally has some body and movement. It's about working with what you have, and letting your hair do its own thing, more or less.

Achieving a Natural Flow

To get a longer, more relaxed Cillian Murphy look, the first step is, quite simply, to let your hair grow out. This might take some patience, as hair growth varies for everyone. During this growing-out phase, you might want to get regular trims to remove split ends and maintain a healthy shape, so it doesn't just look messy, apparently.

Once you have some length, ask your barber or stylist for a cut that enhances your natural texture. This might involve some layering to reduce bulk and add movement, especially if your hair is thick. The goal is to create a shape that looks good even when styled minimally, which is rather convenient, too.

For styling, often less is more with these looks. A light styling cream or a sea salt spray can help define waves and add texture without making the hair stiff. You can let it air dry for a truly natural finish, or use a diffuser on a low heat setting if you are in a hurry, you know?

Styling for Texture

When you have longer hair, playing with texture can really change the whole look. Cillian Murphy often lets his natural waves or a slight tousle come through in these styles. This adds a certain depth and character to his appearance, which is quite appealing, really.

To enhance texture, you could try using a texturizing spray or a light matte paste. Apply it to damp hair and scrunch it gently with your hands to encourage waves. You can also work it through dry hair for a more lived-in, slightly undone look, which is pretty much always a good option.

Brushing too much can sometimes flatten natural texture, so consider using your fingers to style or a wide-tooth comb. The idea is to create a relaxed, effortless vibe, as if you just woke up looking this good, or something like that, anyway. This approach allows your hair to look natural and feel comfortable, which is very important for many people.

The Neat and Classic Looks

In addition to his more dramatic or relaxed on-screen hair, Cillian Murphy also often sports very neat, classic short hairstyles, especially for red carpet events or in roles where a polished look is needed. These styles are clean, well-groomed, and often involve a side part or a subtle sweep back. They show a different side of his overall look, you know, a more refined one.

These classic cuts are versatile and timeless, suitable for many different occasions. They emphasize a clean-cut appearance and can make a face look sharper and more defined. It's a look that speaks of sophistication without being overly fussy, which is quite appealing, apparently.

Whether it is a short back and sides with a bit of length on top, or a slightly longer, combed-over style, these looks are about precision and good grooming. They are a staple for many men, and Cillian Murphy wears them very well, really.

The Oppenheimer Influence

In his Oscar-winning role as J. Robert Oppenheimer, Cillian Murphy's hair was often seen in a neat, somewhat period-appropriate short style. This look was fairly modest, reflecting the character's intellectual and serious nature. It wasn't about flash, but about a practical, well-kept appearance, so it fit the role perfectly.

This kind of haircut is typically shorter on the sides and back, gradually blending into a slightly longer top. It's often styled with a clean side part, kept close to the head. It's a very traditional and respectable look, you know, the kind that never really goes out of style.

If you liked his *Oppenheimer* hair, you're probably looking for something that is both tidy and easy to manage. It's a classic choice that works for many face shapes and hair types, and it gives a very put-together impression, which is always good, honestly.

Styling a Shorter Cut

For these neat and classic Cillian Murphy hairstyles, styling is all about control and polish. You will want to use a product that provides a clean finish without too much shine or stiffness. A light pomade or a matte styling cream can work wonders, so that's something to consider.

Apply a small amount of product to damp or dry hair, then use a comb to create a sharp side part and sweep the hair into place. For a slightly more relaxed but still neat look, you can use your fingers to gently guide the hair. The key is to keep it smooth and tidy, so no stray hairs, basically.

These styles are great because they are relatively low maintenance once you have the cut right. A quick comb-through in the morning is often all you need to look sharp. They are perfect for professional settings or any time you want to present a very clean and refined image, which is pretty much always a good idea.

Evolving Hair Over Time

Looking at Cillian Murphy's career, it is clear that his hairstyles have changed quite a bit over the years. From his earlier days in films like *Disco Pigs* to his more recent, Oscar-winning performance in *Oppenheimer*, his hair has often reflected the characters he plays or the period of time. This shows his willingness to change his appearance for a role, which is a sign of a truly dedicated actor, you know?

He has had longer, shaggier hair in some roles, then very short, military-style cuts in others. This variety is part of what makes his overall look so interesting. It also shows that he is not afraid to experiment with his hair, which can be inspiring for anyone looking to try something new, apparently.

His natural hair color is a rather deep brown, and he usually keeps it that way, letting the cut and style do most of the talking. This focus on shape and texture, rather than color, is a hallmark of his approach to grooming, and it works very well for him, really.

Even with his upcoming hiatus from acting in 2025, it is likely that Cillian Murphy will continue to influence hair trends, simply by being himself.

Not every style works for everyone, and that is perfectly okay. The goal is to find a look that makes you feel good and is manageable for you, you know?
