Hair extensions are a convenient solution for adding length and volume that natural hair growth alone might not achieve. As Vietnamese hair continues to be a top choice for hair vendors worldwide, understanding its quality grading system is crucial. This classification helps vendors determine the best match for their customers in terms of price, quality, and specific needs. In this guide, we will explore the different quality grades of Vietnamese hair and how they impact the hair industry.
1. What Are the Quality Grades of Vietnamese Hair?

Vietnamese hair is commonly classified into three main categories based on hair thickness within a bundle. The thicker the bundle, the higher the quality and price. The three main grades include:
- Single Drawn Hair
- Double Drawn Hair
- Super Double Drawn Hair
These classifications help distinguish hair quality and ensure customers receive products that meet their expectations.
2. Classification of Vietnamese Hair Grades
1. Single Drawn Hair

a. Definition
Single-drawn hair is the lowest thickness grade among Vietnamese hair classifications. Typically, only 40-50% of the strands are the same length, while the rest vary, creating a natural, tapered effect. The roots appear thick, but the ends are thinner.
b. Pros and Cons
Pros:
- Natural look: Mimics the way hair naturally grows from the scalp.
- Affordable: The least expensive option among the three grades.
Cons:
- Less volume: Not ideal for those seeking a fuller, voluminous look.
- Requires trimming: To achieve a uniform thickness, trimming the ends may be necessary.
2. Double Drawn Hair

a. Definition
Double-drawn hair is a mid-range option where approximately 60-65% of the strands are the same length. Shorter hairs are removed by hand, making the bundle appear fuller from top to bottom.
b. Pros and Cons
Pros:
- More volume: Provides a thicker and more glamorous look compared to single-drawn hair.
- Fewer bundles needed: Requires fewer extensions to achieve a full look.
Cons:
- Higher cost: More expensive than single-drawn hair due to additional processing.
This grade is the most popular among customers, particularly in Africa, as it offers a balance between price and quality.
3. Super Double Drawn Hair

a. Definition
Super double-drawn hair is the highest-quality grade, consisting of 80-90% of the strands being the same length. The result is an extremely full, thick bundle from root to tip.
b. Pros and Cons
Pros:
- Maximum volume: Ideal for achieving luxurious, thick hairstyles.
- Natural appearance: The most realistic and uniform look.
- Requires fewer bundles for full coverage.
Cons:
- High cost: The most expensive option due to extensive processing and high hair quality.
