Vietnamese Hair Bundles: A Complete Guide for Buyers
18/10/2026

Vietnamese hair bundles are human hair sewn onto a weft and sold by weight and length, most often around 100 g (3.5 oz) per bundle, though each vendor sets its own. They come raw, steam-patterned or colored, in straight, wavy and curly. Get those basics straight and the rest, from how many bundles an install takes to which order will sell, gets much easier to call.
Three kinds sell under that name, and they aren't the same product:
Weight is the other half of the spec. Many vendors sell 100 g bundles, but some go lighter, and weight can vary by a few grams within one order. Longer hair at the same weight is thinner, so a 26-inch bundle looks less full at the ends than an 18-inch one. Compare weights before comparing prices, and use our hair weave length chart to see where each length lands on the body.
Leave-out styles can often use one bundle fewer than a full sew-in, since your own hair covers part of the head. If you're adding a closure or frontal, three bundles plus the lace piece covers many mid-length installs. Matching sets are on our bundles with closure page.

What Are Vietnamese Hair Bundles?
A bundle is a length of hair machine-sewn along one edge into a weft, which a stylist then sews onto braids or a wig maker sews onto a cap. "Vietnamese" refers to where the hair was collected and, usually, where it was made up.Three kinds sell under that name, and they aren't the same product:
- Raw: not steamed, dyed or permed, so it keeps its natural pattern and a bit of color variation between bundles.
- Virgin, steam-patterned: no dye or perm, but the wave or curl was set with heat and steam. It's a valid product, just not raw.
- Colored: lifted and toned (613 blonde, ombre, fashion shades), which makes it processed.

Types of Vietnamese Hair Bundles
Texture decides what a bundle is used for, and which questions your customers send back.Wall displays of hanging hair bundles under signs reading "Baby Thin Hair" and "Raw Hair"
Straight
Natural straight and bone straight are the easy sell: they suit sew-ins, wigs and colored work, and they show off the cut. Natural straight keeps a little movement, while bone straight is flat and sleek. Ours are listed on the natural black hair weave page.Wavy
Body wave is the safe middle, a loose S-shape that's easy to wear. Deep wave holds a more defined pattern, so it reads bolder on the head. Wavy hair also draws up when it springs back, so it needs more length on the label than straight to hang at the same spot.Curly
Curly sells to buyers who want texture without a curling iron, but it generates the most questions. Tight curl can lose several inches once it's worn, and customers often order the wrong length the first time. We'd go heavier on straight and one wave for a first order and add curl once you know your repeat buyers.Vietnamese Hair Bundle Lengths and Weight
Bundle length is measured with the hair pulled straight from root to tip. A straight bundle labeled 18 inches (46 cm) gives you close to 18 inches on the head. A deep wave or curly bundle with the same label will sit shorter, because the pattern pulls the hair up.Weight is the other half of the spec. Many vendors sell 100 g bundles, but some go lighter, and weight can vary by a few grams within one order. Longer hair at the same weight is thinner, so a 26-inch bundle looks less full at the ends than an 18-inch one. Compare weights before comparing prices, and use our hair weave length chart to see where each length lands on the body.

How Many Vietnamese Hair Bundles Do You Need?
It depends on length, thickness and style. The numbers below assume 100 g bundles, so scale them if your bundles weigh less.For sew-in hairstyles
| Length | Bundles for a full sew-in | What changes it |
| 10-16 in (25-41 cm) | about 2-3 | Thick hair or a full look needs the 3 |
| 18-24 in (46-61 cm) | about 3-4 | Wavy and curly textures lean toward 4 |
Leave-out styles can often use one bundle fewer than a full sew-in, since your own hair covers part of the head. If you're adding a closure or frontal, three bundles plus the lace piece covers many mid-length installs. Matching sets are on our bundles with closure page.
For wigs
A wig takes a different count than a sew-in. For a wig made on a cap, most makers land around 2-3 bundles at 12-16 inches, 3-4 at 18-24 inches and 4 or more past that, with density as the main variable. A fuller density needs the higher number. Many wig makers buy loose bulk hair by weight instead of bundles, so ask for both and compare the price per gram.For longer lengths
At 26 inches and up, plan on 4-5 bundles for a full head, and more for very thick hair. Long bundles show their weakness at the ends, which is where double drawn pays off: fewer short hairs means the ends stay fuller instead of thinning to wisps. Ask whether the bundles you're pricing are single or double drawn, because the label isn't standardized and each factory draws its own line.How to Choose Quality Vietnamese Hair Bundles

You can check most of it yourself in ten minutes.
- Weigh a few bundles on a kitchen scale. A few grams of spread is normal; a big gap isn't.
- Pull one straight along a ruler and check the length, then look at the ends. Thin, see-through tips mean short hairs were left in.
- Check the weft. The stitching should be even, with no loose spots, and a gentle tug shouldn't shed handfuls.
- Look at color in daylight. Raw bundles vary a little; a bundle that's clearly another shade is a problem.
- Wash one bundle and air dry it. Good hair settles back into its pattern with no heavy coating and no chemical smell.
How to Care for Vietnamese Hair Bundles

Wash a new bundle before you style it, then treat it like your own hair, only gentler. Use a sulfate-free shampoo and conditioner, work from the ends upward, and finger-detangle wet hair instead of raking it. Wavy and curly bundles tangle faster, so keep them well conditioned.
Air dry when you can. Heat is fine on straight bundles with a protectant, but steam-set waves and curls can loosen with repeated heat, and raw hair reacts to the product you put on it. With proper care, good bundles can be worn and styled for a year or more, though it varies by texture and how often they're worn. For wearing and washing tips, see how to care for human hair weave.
