Undercut & Slicked Back Haircuts: The Complete Guide
The undercut and slicked back hairstyles are two of the most versatile men’s cuts — sharp enough for the office, bold enough for a night out. This guide covers every variation, how to style them, and who they suit best.
What Is an Undercut?
An undercut is a hairstyle where the sides and back are cut short (clipped or faded) while the hair on top is left significantly longer. The contrast between the short sides and long top is the defining feature. The top hair can be styled in many ways — slicked back, textured, quiffed, or left natural.
Types of Undercut Hairstyles
1. Classic Undercut
The sides are clipped short (typically a number 2 or 3 guard) with a clean fade or taper. The top is left 4-6 inches long and can be styled in any direction. A versatile, timeless look.
2. Slicked Back Undercut
The most popular undercut variation. The long hair on top is slicked back using pomade or gel, creating a sleek, polished look. The sides are faded or clipped short. This is the style that works for everything — from job interviews to weddings.
3. Textured Undercut
Instead of slicking the top back, the hair is styled with texture and volume using matte clay or paste. A more casual, modern take on the undercut. Great for guys who want a lived-in, effortless look.
4. Long Undercut
The top hair is grown out long (6+ inches) while the sides stay short. Can be worn down, tied back, or styled up. A bold, statement look that requires commitment to grow out.
5. Skin Fade Undercut
Combines a skin fade on the sides with long hair on top. The fade creates a sharp, clean contrast. The top can be slicked back, textured, or styled as a quiff or pompadour.
What Is a Slicked Back Hairstyle?
Slicking your hair back is a styling technique, not a specific cut. It involves using product (pomade, gel, or wax) to comb the hair back away from the face. It works with an undercut, a fade, or even longer all-over hair.
The slicked back look has been popular since the 1920s and has evolved through every decade. It’s a timeless style that signals confidence and grooming awareness.
How to Style a Slicked Back Undercut
What You’ll Need
- Pomade or styling wax: For hold and shine. Use water-based pomade for easier washing.
- Comb: A fine-tooth comb for a sleek look, or a wide-tooth comb for more texture.
- Hairdryer: Essential for setting the style.
- Pre-styler (optional): Sea salt spray or volumising mousse for extra body.
Step-by-Step Styling
Step 1: Start with towel-dried hair (damp, not dripping wet).
Step 2: Apply a small amount of pre-styler if using (sea salt spray works well for volume).
Step 3: Blow-dry the hair back using your fingers or a round brush. Direct the airflow from front to back.
Step 4: Once dry, take a nickel-sized amount of pomade and rub between your palms.
Step 5: Work the pomade through your hair from front to back, ensuring even coverage.
Step 6: Comb the hair back with a fine-tooth comb for a sleek finish, or use your fingers for a more natural look.
Step 7: Check the sides and make sure they’re clean and tight.
Which Face Shape Suits an Undercut?
| Face Shape | Suits Undercut? | Best Variation |
|---|---|---|
| Oval | ✅ Yes — all variations | Any style works |
| Round | ✅ Yes — adds angles | High fade undercut, textured top |
| Square | ✅ Yes — balances jaw | Classic undercut, slicked back |
| Oblong | ⚠️ Be careful | Avoid very long top — keeps proportions balanced |
| Diamond | ✅ Yes — adds width on top | Textured undercut, quiff |
Undercut Maintenance
- Trim frequency: Every 2-3 weeks for the sides. The top can go 4-6 weeks between trims.
- Product buildup: Wash pomade out thoroughly. Use a clarifying shampoo once a week if you style daily.
- Growing it out: Undercuts grow out awkwardly. Plan for an awkward phase of 2-3 months if you’re going for a longer all-over style.
