In recent years, the undercut has gone from an edgy, niche hairstyle to a mainstream style statement, especially when paired with hair extensions for added length, volume, or even color.

Undercuts are ideal for those who want a bit of boldness while keeping options open for styling versatility. This guide takes you through 10 unique undercut styles with hair extensions, plus everything you need to know about the trend, from benefits to drawbacks.

What Is an Undercut?

An undercut is a hairstyle where a section of hair—usually around the lower back or sides of the head—is shaved or closely trimmed, leaving the top layers of hair longer.

This contrast creates a dramatic look and allows for easy styling options, from sleek and polished to edgy and rebellious.

Why Would You Get an Undercut?

Getting an undercut offers multiple benefits. For starters, it’s a way to reduce bulk, making thick or long hair more manageable.

It’s also a style statement, giving you the ability to switch from professional to playful, depending on how you style the top layers. For those with hair extensions, an undercut can add dimension and create an eye-catching look.

Pros and Cons of an Undercut

Pros

• Style Versatility: Allows you to experiment with both bold and subtle styles.
• Reduced Bulk: Perfect for thick hair, as it removes excess volume.
• Cooler in Summer: An undercut keeps you cool by removing hair from the neck area.
• Styling Options: Extensions can be added or removed, giving endless styling possibilities.

Cons

• Frequent Maintenance: Requires regular trims to keep the undercut neat.
• Commitment to a Bold Look: Some styles may be harder to hide.
• Regrowth Process: Growing out an undercut can be awkward if you want to transition back to a full head of hair.
