Introduction

Choosing the right hair system can dramatically improve your appearance, confidence, and daily styling experience. Among all modern hairpiece bases, Skin Base systems remain one of the most natural-looking and realistic options.

But not all skin bases are made the same.
The three main techniques — V-loop, Knotted, and Injection — each offer unique benefits in naturalness, durability, and styling flexibility.

This guide breaks down these techniques in an easy-to-understand way, helping you choose the perfect hair system for your needs.

What Is a Skin Base Hair System?

A Skin Base system uses a thin polyurethane (PU) material that mimics the appearance of natural scalp. It blends seamlessly with your skin, offering:

• Ultra-realistic look

• Lightweight and comfortable wear

• Highly natural hair growth appearance

• Ideal for short and medium hairstyles

1. V-Loop: The Most Natural, Knotless Technique

What Is V-Loop?

V-looping uses a “V-shaped” loop to implant hair without knots. The result is an ultra-natural front hairline and soft, flowing hair movement.

Advantages

• Completely knotless

• Most realistic hairline in the industry

• Perfect for brushed-back or lifted styles

• Extremely thin and lightweight

Considerations

• Less durable than other methods

• Requires gentle handling and proper maintenance

Recommended Product

👉  Ultra-Thin Skin V-Loop (0.03–0.04mm)

2. Knotted: Strongest, Longest-Lasting Skin Base Technique

What Is Knotted?

Hair is tied onto the skin base using tiny knots. While the knots may be slightly visible, this method is the most durable.

Advantages

• Most durable technique

• Holds up well with daily wear

• Ideal for customers needing longevity

• Cost-effective and stable

Considerations

• Knots may be visible (can be bleached depending on color)

• Front hairline is less natural than V-loop

Recommended Product

👉 Super Thin Skin with Knotted Back / 1/8 V-Loop Front

3. Injection: The Most Realistic Top View

What Is Injection?

Injected hair enters the base vertically and locks beneath the PU layer. This creates a “hair growing out of the scalp” illusion.

Advantages

• Highly realistic top view

• Smooth, soft feel

• Excellent for fuller, natural-looking crown

Considerations

• Medium durability

• Higher production cost

• Slightly longer manufacturing time
