Human Hair Bundles Grade Explained: What Do 8A, 10A & 12A Mean?

If you have been shopping for human hair bundles, you have probably seen grades like 8A, 10A, or even 12A. But what do these numbers really mean? Does a higher grade always mean better quality?

The truth is, human hair bundles grade is not an official industry standard. These grades are marketing terms used by suppliers to describe differences in hair quality.

However, there is no organization that defines what qualifies as 10A, or 12A hair. Because every supplier can create their own grading system, a 12A bundle from one company may not be the same as a 12A bundle from another.

That means the number of A’s can be a reference when comparing products from the same supplier, but it should not be the only factor you consider when choosing human hair bundles.

What Should You Look For Instead of Hair Grades?

Since hair grades are not standardized, it is more helpful to understand what these grades are usually trying to describe.

Thickness From Root to Tip (Less Short Hair)

One of the biggest differences between different hair grades is usually the amount of shorter hair mixed into the bundles.

In many suppliers’ grading systems, a higher number of A’s often means the bundle contains fewer short hairs and has better thickness from root to tip.

For example, within the same company, a 12A bundle may contain fewer shorter hairs than a 10A bundle, making the ends look fuller and more even.

Hair Type: Raw Hair vs Virgin Hair

After understanding what hair grades mean, there is another factor that can be even harder to judge: hair type.

You probably don’t want to choose a bundle simply because it has fewer short hairs, only to find that the hair tangles easily after a few wears.

This is why understanding the difference between raw hair and virgin hair can help you make a better decision.

Raw hair is considered one of the most premium options because it is unprocessed and keeps the hair’s natural characteristics. It can be very durable with proper care, but it also requires more maintenance and usually comes with a higher price.

Virgin hair is a more popular choice for many customers because it offers a good balance between quality, appearance, and affordability. With proper care, high-quality virgin hair can also last a long time, making it a practical option for everyday wear.

Single Weft vs Double Weft Hair Extensions

When buying human hair bundles, one of the biggest concerns is how long they will last. Hair grade can tell you something about the bundle quality. However, weft construction is another important factor that affects how the bundles look and perform.

Single weft hair extensions are made with one layer of hair sewn onto the weft. They are lightweight and work well for clients who prefer a more natural look, less weight, or a flatter installation.

Double weft hair extensions have two layers of hair sewn together, creating a thicker and fuller bundle. Because they provide more density, you may need fewer bundles to achieve your desired look. This can also make the installation process more efficient.

For many Black women, double weft extensions are a popular choice for sew-ins and quick weaves. They provide the fullness and volume that many textured styles need.

The length and number of bundles you choose also play an important role in achieving your desired style. If you are unsure what length is right for you, check out our guide on What Length Bundles Should I Get?

Final Thoughts
