Vietnamese Hair - Premium Glueless Wig Wholesale Vendor

3 Key Criteria to Identify a Trustworthy Vietnamese Hair Supplier

Vietnamese hair is becoming one of the most preferred choices in the global wig and extension market. But the final quality of any product depends heavily on the supplier you choose. Evaluating a supplier correctly helps you avoid risks and secure long-lasting, high-quality hair. Below are the three most important criteria to check before working with any Vietnamese hair supplier.

1. Check the Hair Source: Single Donor vs. Multiple Donor

Unlike Chinese suppliers who grade hair using the 8A–12A scale, Vietnamese hair is evaluated by its origin.

Two Main Types of Vietnamese Hair

✔ Single Donor

Collected from one person only
Naturally uniform color and texture
Rare and high-priced
Best for premium wigs that require top-tier quality

✔ Multiple Donor

Most common type in Vietnam
Each bundle is manually sorted strand by strand
Usually divided into 2–3 quality levels:

Level 1

Shiny, raw, and chemical-free
Can bleach to blonde
About 10% faulty strands

Level 2

Slightly less uniform
Can bleach but with ~20% faults

Level 3

Lowest quality
Not suitable for light colors; typically dyed dark

👉 Always ask for a clear explanation of hair type and bleaching error rate to avoid misunderstandings.

well-selected multiple-donor hair can have a quality close to single-donor hair, while costing only half the price.

2. Check the Drawn Level (Thickness From Root to End)

“Drawn” shows how many strands in a bundle share the same length.

Common Drawn Levels in Vietnam

✔ Single Drawn (~25%)

Most strands are different lengths
Natural look but not very thick
Lowest price

✔ Double Drawn (~50%)

More uniform strands
Full from roots to ends
Best-selling option

✔ Super Double Drawn (75%+)

Highly uniform
Very thick; ideal for luxury wigs
Higher labor cost = higher price

👉 Request videos or photos of the bundle spread out to verify true thickness.

To check the bundle’s drawn level, just look at the thickness of the ends.

3. Check Density and Knot Quality in Closures & Frontals

With closures and frontals, craftsmanship matters the most.

Why Density and Knot Size Matter

Labor is the biggest cost
Density affects realism and styling
Knot size determines how well the lace blends with the scalp

Reality in the Market

Density numbers (100%, 150%, 200%) vary widely—there’s no unified standard, and advertised values may not match the real product.

👉 Ask the supplier for:

Close-up videos of the lace roots
Clear knot visibility
Side-by-side density comparison

The denser and smaller the knots, the more natural and beautiful the hair looks

To choose a reliable Vietnamese hair supplier, focus on these three core factors:

Hair origin (single donor or multiple donor)
Drawn level
Density and knot quality

Evaluating these points helps you secure consistent, high-quality Vietnamese hair suitable for the global market.
