The Ultimate Guide to the Undercut Hairstyle

The undercut has been one of the most popular men's hairstyles for over a decade — and it shows no signs of fading. It's bold, versatile, and works with almost every hair type and face shape. This guide covers everything you need to know about the undercut, from its variations to styling techniques.

What Exactly is an Undercut?

An undercut is characterized by a stark contrast between the top and sides of the head. The sides and back are cut very short (often buzzed or shaved), while the top is left significantly longer. Unlike a fade, which gradually blends from short to long, the undercut creates a distinct, disconnected line.

Key characteristics:

• Dramatic contrast between top and sides
• Disconnected look (no blending)
• Short or shaved sides and back
• Longer, styled top section

Popular Undercut Variations

Classic Undercut

The original undercut features uniformly short sides with a slicked-back or side-parted top. It's clean, professional, and timeless.

• Sides: #1 to #2 guard, all one length
• Top: 3-6 inches, slicked back or parted
• Best for: Professional settings, classic style lovers
• Face shapes: Oval, square, heart

Disconnected Undercut

This variation emphasizes the contrast even more, with a very distinct line where the short sides meet the longer top. No blending whatsoever.

• Sides: Skin to #1 guard
• Top: 4+ inches with hard line separation
• Best for: Bold, fashion-forward looks
• Face shapes: All shapes, especially angular faces

Undercut with Fade

A hybrid style that combines the undercut's length contrast with a fade on the sides. It's more versatile and slightly less dramatic than a pure undercut.

• Sides: Faded from skin to #2-3
• Top: 3-5 inches
• Best for: Those who want contrast but not too extreme
• Face shapes: All face shapes

Textured/Messy Undercut

Instead of slicking the top back, this version features a textured, tousled top. It's more casual and contemporary.

• Sides: #1 to #2 guard
• Top: 3-5 inches with layers and texture
• Best for: Casual, everyday style
• Face shapes: Round, oval, heart

Long Top Undercut

An undercut with extra length on top — typically 6+ inches. Can be worn as a man bun, ponytail, or flowing freely.

• Sides: #1 to #2 guard
• Top: 6-10+ inches
• Best for: Artistic, creative types
• Face shapes: Oval, oblong

Curly Undercut

Curly hair and undercuts work beautifully together. The contrast between short sides and curly top creates a striking look.

• Sides: #1 to #2 guard
• Top: 3-5 inches of natural curls
• Best for: Men with natural curls or waves
• Face shapes: All face shapes

How to Style an Undercut

The versatility of the undercut means you can style the top in various ways:

Slicked Back

1. Apply pomade or gel to damp hair
2. Comb hair straight back from forehead
3. Use a blow dryer on low heat to set
4. Finish with a light hairspray if needed

Side Part

1. Find your natural part line
2. Apply pomade or cream to damp hair
3. Comb hair to the side, following the part
4. Use fingers for a more relaxed look

Textured/Messy

1. Apply matte clay or wax to dry hair
2. Work product through with fingers
3. Push hair up and back, creating texture
4. Scrunch and separate for more definition

Undercut Maintenance

• Sides: Need trimming every 2-3 weeks to maintain the crisp contrast
• Top: Trim every 4-6 weeks depending on desired length
• At-home touch-ups: You can maintain the sides with clippers between barber visits
• Daily styling: Most undercut styles require 5-10 minutes of daily styling

Is the Undercut Right for You?

The undercut works best if you:

• Have medium to thick hair
• Don't mind regular barbershop visits
• Are willing to style your hair daily
• Want a bold, statement hairstyle
• Work in a creative or casual environment

You might want to reconsider if:

• You have very thin or fine hair
• Your workplace requires conservative grooming
• You prefer low-maintenance styles
• You have a very round face (though texture can help)
