What Do Hair Grades Mean (Like 10A, 12A, etc.)—and Do They Matter?

You've probably heard of phrases like 8A, 9A, 10A, or even 12A hair if you've ever gone shopping for human hair extensions or wigs. At first glance, it might seem like these labels are a scientific grading system backed by industry standards. But what do these hair grades actually mean? Are they consistent across brands? And most importantly, do they matter when you’re choosing the right hair?

In this post, we’ll break down the hair grading system, what each "A" level represents, whether you should trust these grades, and how to shop smart when it comes to buying high-quality hair.

What Is the Hair Grade System?

The hair grading system is an informal method used by manufacturers and sellers to indicate the quality of human hair extensions. It’s not regulated by any industry standard, so the numbers (e.g., 10A, 12A) can vary in meaning depending on the supplier.

However, generally speaking, the higher the grade, the better the quality of the hair. The scale usually starts around 6A and can go up to 12A or even 14A with some sellers. Let’s explore what these grades typically mean.

Understanding Hair Grades: A Quick Breakdown

6A – Entry-Level Hair

Typically lower-cost virgin hair

May have more short strands

Suitable for short-term styles or limited styling (not ideal for repeated heat or chemical treatment)

7A and 8A – Mid-Range Hair

Usually 100% human hair, possibly mixed with synthetic strands in low-quality versions

Better cuticle alignment

Can be dyed to light brown or blonde

Lasts a few months with good care

9A – High-Quality Virgin Hair

100% virgin hair with intact cuticles

All strands in the same direction (Remy hair)

Can be bleached to light blonde (around 27)

Minimal tangling and shedding

10A Hair Grade

Thicker strands from top to tip

100% unprocessed virgin Remy hair

Can be bleached to 613 (platinum blonde)

Can last over a year with proper care

12A Hair Grade

Premium virgin Remy hair, possibly from single donor

Very thick and full ends

Long-lasting: 1.5 to 2 years with good maintenance

Can handle frequent heat styling and bleaching

Often used in luxury wigs and professional installs

Does Better Hair Always Have a Higher Hair Grade?

Not necessarily.

While higher grades generally indicate better quality, it’s important to remember:

There is no official or standardized grading system. Different vendors might label similar hair as 10A or 12A based on their marketing strategy. One supplier’s 10A could be another’s 8A.

The grade doesn’t tell the whole story. Hair can be labeled 12A, but still be poor in quality if the cuticles aren’t aligned, or if it's not 100% human hair.

What really matters is the source and treatment. Hair from a single donor with intact cuticles and minimal chemical processing will always outperform higher-grade, heavily processed hair.

Virgin Hair vs. Remy Hair: What's the Difference?

To understand hair grades better, you need to know the difference between virgin and Remy hair.

Hair that has never been chemically treated is referred to as virgin hair. It hasn't been chemically straightened, bleached, dyed, or permed. It usually comes from a single donor and retains its natural cuticle alignment.

Remy Hair: Refers to hair where all strands are aligned in the same direction, which helps reduce tangling and shedding. Most high-grade hair (9A and above) is Remy, and can also be virgin.

High-grade hair is often both virgin and Remy, especially grades 10A and 12A.

How Long Does Each Hair Grade Last?

Hair Grade	Expected Lifespan
6A	1-2 months
7A–8A	3–6 months
9A	6–12 months
10A	12–18 months
12A	Up to 2 years

Note: Lifespan also depends on how well the hair is maintained. Heat, bleaching, and styling tools can all reduce longevity.

How to Choose the Right Hair Grade for You

Here are a few tips:

✔ Consider Your Budget

If you’re looking for affordable, short-term hair for a quick style or event, 7A or 8A may do the trick.

✔ Think About Your Styling Habits

Do you use heat styling or bleaching? If yes, invest in 10A or 12A hair to avoid damage and get the best results.

✔ Longevity Matters

If you want hair that will last for a year or more, go for 12A hair and treat it well.

✔ Ask Questions Before You Buy

Always ask the seller about:

Source of the hair

Whether it’s 100% human hair

If it’s virgin or chemically treated

How the cuticles are aligned

If they can’t answer clearly, you may want to shop elsewhere.

Final Verdict: Do Hair Grades Really Matter?

Yes—and no.

They matter as a general guide to hair quality, especially if you’re buying from a trusted source. But since there’s no industry standard, you shouldn’t rely on the number alone.

Instead, look at:

The reputation of the seller

Customer reviews and photos

Return policies and guarantees

Product details and transparency

Use the hair grade as one data point in your decision—not the only one.

Hair grades like 10A and 12A give a helpful overview of quality, but they’re not foolproof. Knowledge is your best defense as a customer. By understanding what these grades typically represent, you can make better choices and avoid overpriced or low-quality hair.
