Single vs Double vs Super Double Drawn: The Complete Guide to Vietnamese Hair Grades

In the global hair industry, few things are as confusing as the grading system. You see terms like “SD,” “DD,” and “SDD” everywhere, but what do they actually mean for your hairstyle and your budget?

At XHair, we believe an educated customer is our best partner. The difference between these grades isn’t about the quality of the hair fiber (all our hair is 100% premium human hair)—it is about the density at the ends. Understanding this distinction is crucial when importing Vietnamese Hair to ensure you get the exact volume you are paying for.

Here is the ultimate breakdown of Single Drawn, Double Drawn, and Super Double Drawn Vietnamese Hair, and how to choose the right one for your business. 

What is Single Drawn Vietnamese Hair?

Single Drawn hair is the most common grade found in the market and is often the entry-level choice for budget-conscious buyers.

Characteristics of Single Drawn Vietnamese Hair

In a Single Drawn bundle, the hair typically mimics natural growth. Think of your own natural ponytail: it is thick at the roots but naturally tapers and thins out towards the ends.

• Fullness: Approximately 50% of the hairs are the full length. The other 50% are shorter strands mixed in.
• Appearance: The bundle is thick at the weft (root) but becomes noticeably thinner at the tips.
• The “Ponytail” Effect: This grade provides a very natural finish because real hair rarely grows at the exact same length.

Who Should Choose Single Drawn Vietnamese Hair?

This grade is perfect for clients who want a lightweight feel and a natural look. It is also an excellent option for those on a budget who want the quality of Vietnamese Hair without the premium price tag of high-density ends.

What is Double Drawn Vietnamese Hair?  

Double Drawn is the sweet spot. It is the most popular grade among professional salons in Europe and Africa because it balances cost with impressive volume. 

Characteristics of Double Drawn Vietnamese Hair

To create this grade, factory workers manually remove a significant portion of the shorter hairs from the bundle before wefting.

• Fullness: Approximately 70% to 75% of the hairs are the full length.
• Appearance: The hair remains thick from the root down to the mid-lengths, with only a slight taper at the very ends.
• Volume: It offers a much fuller appearance than Single Drawn, eliminating the “stringy” look.

Why Double Drawn Vietnamese Hair is a Bestseller

For most hairstyles—whether layers, curls, or waves—Double Drawn provides enough density to look voluminous and luxurious. It allows stylists to cut and blend the extensions easily without losing too much length.

What is Super Double Drawn Vietnamese Hair? 

If you are looking for the thickest, heaviest, and most glamorous hair on the market, Super Double Drawn (SDD) is the answer. This is the grade often seen on Instagram influencers and celebrities. 

Characteristics of Super Double Drawn Vietnamese Hair

This is a labor-intensive product. We aggressively remove almost all short strands, ensuring the bundle is uniform from top to bottom.

• Fullness: Approximately 85% to 95% of the hairs are the full length.
• Appearance: The density at the tip is almost identical to the density at the root. It looks like a blunt cut.
• Weight: These bundles feel heavier and more substantial.

The Ultimate “Bone Straight” Experience

Super Double Drawn is the preferred grade for Vietnamese Bone Straight Hair. When the hair is meant to be glass-straight, any thinness at the ends becomes visible. SDD ensures that the sleek look remains solid and impactful all the way down.

Why Vietnamese Hair is Superior for All Grades

You might wonder: “Can’t I just buy Super Double Drawn hair from China, India, or Brazil?” Technically yes, but the results won’t be the same. Vietnamese hair outperforms other origins across all grades for specific biological and environmental reasons.

Naturally Thick Hair Structure

Vietnamese hair strands are genetically thicker in diameter than hair from many other regions. This natural thickness means:

Even Single Drawn looks fuller: A Single Drawn bundle of Vietnamese hair often appears thicker than a Double Drawn bundle of finer hair from elsewhere. The individual strands themselves are more substantial.

Double and Super Double are exceptional: When you upgrade to higher grades with Vietnamese hair, the volume becomes truly impressive because you’re starting with naturally thick strands and removing short ones—you’re left with maximum density of naturally strong hair.

Superior Strength and Durability

Vietnamese hair, particularly from donors in rural northern regions, possesses exceptional cuticle strength. This matters because:

Supports heavy wefts: Super Double Drawn wefts are heavy. Weaker hair types can’t support that weight without shedding or breaking. Vietnamese hair maintains integrity even in the densest grades.

Longer lifespan: The natural strength means all grades of Vietnamese hair last longer than alternatives. Single Drawn lasts 1-2 years, Double Drawn 2-3 years, Super Double 3+ years with proper care.

Handles processing better: Whether you’re coloring, bleaching, or heat styling, Vietnamese hair’s robust structure withstands treatment better than weaker hair types across all grades. 

Consistent Quality Standards

Vietnam has become a hub for premium hair production with established quality standards:

• Ethical sourcing practices are well-developed
• Processing methods are refined and gentle
• Quality control is more rigorous than many other origins
• Cuticle alignment is carefully maintained

This means when you order any grade of Vietnamese hair, you’re more likely to receive consistent, reliable quality batch after batch—critical for businesses building reputation on product consistency.
