The Jack Grealish haircut is one of the most talked-about styles in men's grooming right now.
If you have been trying to figure out exactly how to get this look, you are in the right place.
This guide covers what the cut is, how to ask your barber, a full step-by-step breakdown, styling tips, and the best products to use.
I have followed men's haircut trends for years, and this one consistently delivers results. Simple, sharp, and easy to maintain.
What Is the Jack Grealish Haircut?
The Jack Grealish haircut is a slick back undercut. The sides and back are clipped short, while the top is left long at around 5 to 6 inches.
The long hair on top is then pushed back to create that flowing, natural look he is known for.
It sits somewhere between polished and relaxed, which is why so many men are drawn to it.
The style works for everyday wear and smarter occasions. It is clean, low-maintenance once you know how to style it, and suits most face shapes well.
Key Features of the Jack Grealish Haircut
These four elements define the cut and make it work the way it does.
Short Undercut Back and Sides
The sides and back are clipped close to the head using a Grade 1 or skin fade. This short base creates the sharp contrast that makes the whole style stand out.
It is the foundation of the cut and the most important part to get right.
Long Top (5 to 6 Inches)
The top needs to sit at around 5 to 6 inches to flow and push back properly. Too short and it will not hold the style. Too long and it becomes hard to control on a daily basis.
Natural Volume and Flow
The hair on top should move freely and look relaxed rather than stiff. Over-styling with too much product kills the natural finish this cut is known for. The goal is full, easy movement that looks effortless throughout the day.
Optional Headband Look
Jack Grealish wears a thin headband during matches and it has become part of his signature style. You do not need one to pull off the cut successfully.
But a plain black or navy band does complete the look and adds that recognisable Grealish touch.
How to Ask Your Barber for the Jack Grealish Haircut
The right words at the barber chair will save you time and get you the exact result you want.
What to Say (Simple Barber Script)
Keep it direct and simple when you sit in the chair.
Say: "I want a slick back undercut, Grade 1 on the sides, skin fade if possible, and leave the top around 5 to 6 inches." That one sentence gives your barber everything they need to deliver the right result.
Clippers Guide (Grade 1 or Skin Fade)
A Grade 1 leaves roughly 3mm of hair on the sides and back. A skin fade takes it closer to the skin for a sharper, cleaner finish. If you have never had a fade before, start with Grade 1 and adjust from there on your next visit.
Top Length and Texture Details
Ask your barber to add light texture to the top using scissors or a razor. This removes bulk without cutting into the length you need for the style. It helps the hair flow naturally instead of sitting heavy and flat on top.
Jack Grealish Haircut Step-by-Step Guide
Follow each step in order and the result will come together exactly as it should.
Step 1: Grow Your Hair to the Right Length
The top needs to reach at least 4 to 5 inches before you visit the barber. If it is shorter than that right now, give it time and be patient. You simply cannot achieve this style without the right length on top first.
Step 2: Get an Undercut and Protect the Top
Ask your barber for a Grade 1 or skin fade on the sides and back. Show a photo of Jack Grealish if it helps, and make sure the top stays at 5 to 6 inches to hold the style comfortably.
Step 3: Add Texture for Natural Movement
Ask your barber to texture the top before you leave the chair. This removes extra weight from the hair and helps it move freely rather than sitting stiff. It also makes your daily styling routine at home much quicker and easier.
Step 4: Style with Volume and Direction
After washing, towel dry gently and apply your chosen product to damp hair. Use your fingers or a comb to push the hair back and to the side. Let it dry in that direction and the style will hold cleanly throughout the day.
How to Style the Jack Grealish Haircut
Getting the cut is only half the work. Here is how to wear it four different ways.
Slick Back Undercut (Signature Look)
Apply a small amount of pomade to damp hair and use a wide-tooth comb to push everything back from the forehead. Blow dry on low heat or let it air dry in that direction.
This gives the classic Grealish finish with clean movement and a natural shine.
Curtain Bangs Style (Relaxed Look)
Part the hair gently down the middle and let the front sections fall loosely to each side. Use a light hair cream instead of pomade to keep it soft and natural looking.
This version gives a casual, lived-in finish that still looks sharp and intentional.
Styling Without a Headband
Push the hair firmly back and use clay or wax for a stronger hold throughout the day. Dry it in the direction you want it to stay before stepping outside.
Without a headband, the product does all the work of keeping everything neatly in place.
Styling With a Headband
Place a thin, flat headband just behind the hairline after you finish styling the hair. Choose a plain black or navy band for the cleanest and most polished result. It holds the hair back and instantly adds that recognisable Jack Grealish look.
Maintenance Tips to Keep the Haircut Fresh
A few simple habits will keep this style looking clean and sharp every week.
- Trim the sides every 3 to 4 weeks to keep the fade looking fresh and defined.
- Wash hair every other day to maintain natural oils and avoid dryness.
- Apply product to damp hair, not dry, for better hold and a natural finish.
- Use a volumising shampoo if your hair feels flat or lacks body at the roots.
- Sleep on a satin pillowcase to reduce frizz and keep the style intact overnight.
Conclusion
If you want a sharp, easy-to-wear style that works for most hair types, the Jack Grealish haircut is worth trying. I got a version of this cut last year and it quickly became my go-to.
The maintenance is simple, the styling is quick, and it always looks put together. Whether you are heading to the gym or going out, it holds up well.
