Two Block Haircut: The Complete Guide for Men

• The two block is a Korean men's haircut with short sides/back and a long top — the foundation of most K-pop hairstyles.
• It suits all face shapes and hair types when styled correctly, and works especially well for thick, straight Asian hair.
• Popular variations include comma hair, middle part, textured fringe, fade, and perm combinations.
• Maintenance: trim sides every 3-4 weeks. In Singapore's humidity, a cold perm on top reduces daily styling time.
• At a Korean salon, just say "two block" — your stylist will customize the top length, transition style, and fringe to suit your face shape.

Quick answer

A two block haircut is a Korean men's hairstyle where the sides and back are cut short while the top is left significantly longer. The two "blocks" are the short lower section and the long upper section. It's the foundation of almost every K-pop hairstyle you see — from BTS to Stray Kids — and has become the most requested men's cut at Korean salons worldwide. The style works for all face shapes and is designed to be easy to maintain with minimal daily styling.

What is a two block haircut?

The two block haircut divides the hair into two distinct sections. The sides and back are trimmed short — anywhere from a skin fade to a 1-2 inch taper — while the top is left long enough to style in multiple directions. The contrast between these two lengths is what gives the cut its name.

Unlike a traditional Western undercut where the transition between short and long is abrupt, a Korean two block typically features a softer, more blended connection. Korean stylists use techniques like point cutting and slide cutting to create a natural-looking transition rather than a hard line.

The style originated in South Korea in the early 2010s and became a global trend through K-pop and K-drama culture. Today it's the default starting point for Korean men's haircuts — your stylist builds on the two block foundation and customizes the top based on your face shape, hair texture, and personal style.

Popular two block variations

The two block is a framework, not a single look. The sides and back stay short; the top changes based on the variation. Here are the most popular styles we cut at our Orchard salon.

Two block with comma hair

The fringe is styled into a comma shape that curves away from the forehead, creating a soft frame around the face. This is the most requested two block variation right now — it adds a relaxed, effortless K-drama look. Works best with slightly longer fringe (eyebrow to nose-bridge length). A light fringe perm makes the comma shape hold without daily curling iron work.

Two block with middle part

The top is parted down the center with curtain-style fringe falling on both sides. Clean, symmetrical, and versatile — it works in both casual and professional settings. Best for oval and heart-shaped faces. The middle part two block is also the easiest to maintain because gravity does most of the styling work.

Two block with textured fringe

The fringe falls forward across the forehead with choppy, textured pieces. Youthful and casual — this is the classic K-pop idol look. Your stylist uses point cutting to create the piece-y texture rather than a blunt line. Works well on straight, thick Asian hair because the natural density holds the texture without heavy product.

Two block with fade

The sides incorporate a fade (low, mid, or high) instead of a blunt taper. This adds a Western edge to the Korean foundation, with a cleaner transition at the hairline and a more conservative, office-appropriate silhouette. A low taper fade is the most popular option — it keeps the Korean aesthetic while sharpening the side lines. It's also the go-to short two block haircut for men who want a polished, low-maintenance everyday look. At a Korean salon, specify whether you want a taper, low fade, or skin fade — Korean stylists typically default to a softer taper rather than a hard fade.

Two block with perm

A cold perm on the top section adds natural wave and texture, making the two block dramatically easier to style. Instead of blow-drying and using a curling iron every morning, you towel-dry, apply a light styling product, and go. The perm handles the shape. This combination — two block cut plus cold perm on top — is one of the most popular services at Korean salons for men. See our full Korean perm guide for men for details, or if it's your first perm, start with our first-timer's perm guide.

For men with thick side hair that puffs outward within a week of cutting, adding a down perm on the sides flattens the hair against the head and keeps the two block silhouette clean for 2-3 months. The full Korean salon combination — cold perm on top for volume, down perm on the sides for control — is what gives the K-pop two block its sharp, intentional shape on thick Asian hair. Without down perm, thick sides break the silhouette within days of cutting.

Who suits a two block?

The two block works for most face shapes when the top is styled correctly. Here's what Korean stylists recommend.

Round face — add height and volume on top to elongate. Avoid flat, side-swept styles that widen the face. A textured fringe with volume at the crown works well. Consider a perm for added lift.

Oval face — the most versatile shape. Almost any two block variation works. Try the middle part or comma hair.

Square face — soften the angles with a curtain fringe or comma hair. Avoid very short, tight styles that emphasize the jawline. Slightly longer fringe that falls past the brow creates a natural frame.

Long face — keep the top shorter and add width rather than height. A middle part with volume on the sides works better than a tall, voluminous top. Avoid adding too much height at the crown.

Heart-shaped face — balance a wider forehead with fringe that covers it partially. The textured fringe or curtain bang variation is ideal.

The two block also works well across different hair textures. Thick, straight Asian hair holds the two block shape naturally because the density supports the longer top section. Thinner hair can benefit from a cold perm or root perm to add body at the crown.

How to ask your stylist for a two block

At a Korean salon, saying "two block" is usually enough — your stylist knows the cut and will ask you about the details. But if you want a specific variation, here's what to communicate.

Three things to specify:

1. Sides and back — how short? Options range from a clean taper (scissors, no skin visible) to a low fade (gradual skin fade at the hairline) to a disconnected undercut (sharp line between short and long). Most Korean two blocks use a soft taper, not a hard fade.

2. Top length — how long? Short (2-3 inches) for conservative, medium (4-5 inches) for classic K-drama, or long (6+ inches) for dramatic comma hair or flowing styles.

3. Fringe style — how do you want the front styled? Comma, middle part, textured forward, side-swept, or pushed back.

Bring a reference photo. This is the single most effective thing you can do. Show your stylist exactly what you want and they'll adapt it to your face shape and hair type.

Styling a two block in Singapore's humidity

Singapore's 80-90% humidity is the main challenge for any styled men's cut. Here's what actually works.

Without a perm: Blow-dry the top into shape immediately after washing. Use a matte clay or wax (not gel — gel melts in humidity) to hold the shape. Reapply a light finishing spray if needed midday. Budget 5-10 minutes in the morning.

With a perm: Towel-dry, scrunch in a light curl cream or sea salt spray, and go. The perm does the work. Budget 2 minutes. This is why the two block + perm combination is so popular in Singapore — it's the most practical approach to maintaining a styled look in tropical heat.

For thick side hair: If your sides puff outward within days no matter what product you use, the issue isn't your styling — it's hair density meeting humidity. A down perm on the sides solves this for 2-3 months. After down perm, your sides stay flat through 80%+ humidity without any product at all. Paired with a cold perm on top, your morning routine drops to zero.

Products that work in Singapore's climate:

• Matte clay or wax (holds in humidity, not shiny)
• Light hold hairspray (final layer of hold)
• Avoid water-based gels (dissolve in humidity) and heavy pomades (look greasy fast)

How to maintain a two block

Sides and back: Trim every 3-4 weeks. The two block silhouette depends on the short-to-long contrast — when the sides grow out, you lose the shape. In Singapore's humid climate, overgrown sides also get puffier faster.

Top: Can go 6-8 weeks between trims depending on growth rate and how much length you want. Your stylist will clean up the shape, thin out bulk if needed, and maintain the face-framing pieces.

If you have a perm: The perm lasts 3-6 months. As it grows out, the curl loosens naturally — no awkward grow-out phase. When the texture is gone, either re-perm or transition to a blow-dried styling routine.

Daily care: Use a lightweight shampoo every 1-2 days (daily washing strips natural oils that help with styling). Conditioner on the top section only — you want the sides to stay flat and controlled.

Two block vs undercut: what's the difference?

Both cuts feature short sides and a longer top, but the execution and aesthetic are different.

Many modern two blocks incorporate elements of both — a soft Korean taper with a low fade, for example. At our salon, your stylist can adjust the transition based on whether you prefer a cleaner Western edge or a softer Korean blend.

Where to get a two block in Singapore

For the best results, visit a Korean salon where stylists are trained in Korean cutting techniques. The two block is a standard cut at Korean salons — the stylist understands the nuances of transition blending, face-shape adaptation, and Asian hair texture that a typical barber may not.

At Miin in Orchard, our Korean men's haircut starts from $38 with wash and styling included. Every cut begins with a face shape consultation, and your stylist will recommend the best two block variation for your features.

If you want to combine a two block with a cold perm for easier daily styling, mention it when booking so we allocate enough time for both services.
