Understanding Hair Grades: What 10A, 12A and, 16A Really Mean

9A, 10A, 12A, 16A. If you've been shopping for bundles lately, you've seen these hair grades everywhere, and every listing seems to have a bigger number than the last. It's easy to assume the highest grade means the best hair. The real tea is that there's no official standard behind any of it. Once you know what these labels actually mean, you can shop for your next install with total confidence.

As the #1 virgin hair supplier in the nation, She's Happy Hair has spent years helping stylists and hair lovers find bundles they're obsessed with. Let's break down the grades of human hair, what each label usually means, and how to tell what you're really getting.

Hair grades are the labels, like 8A or 12A, that sellers use to describe the quality of human hair bundles. The idea is simple: a higher number is supposed to mean healthier, softer, and less processed hair.

What a lot of shoppers don't realize is that no official organization creates or checks these grades. Each supplier decides what its own grades mean. That's why one brand's 10A can look and feel totally different from another brand's 10A. The numbers keep climbing too. Not long ago, 10A was the top of the scale, and now 12A, 15A, and 16A are all over your feed.

So treat the grade as your starting point. The details behind the hair are where the real story lives.

Here's how the different grades of hair are usually used across the industry. Since there's no official standard, think of this chart as a guide to common seller language rather than a certified scale.

When you're investing in premium hair, a few key terms tell you more than any grade can. Each one describes something different, so let's get into it.

Raw hair is human hair that hasn't been chemically altered at all. It keeps the donor's natural texture, color, and strand variation, exactly the way it grew. Raw Indian hair, for example, is commonly sourced from hair donated at temples in South India.

Virgin hair hasn't been colored or permed, but the word gets used pretty loosely in the hair world. Some virgin hair is steamed to create a wave pattern or lightly treated for a more uniform look. Raw hair stays as close to its natural state as it gets.

You'll also spot the word Remy on a lot of listings. Remy refers to cuticle alignment, meaning the cuticles all run the same direction from root to tip. That's its own separate trait, while raw is all about how the hair has or hasn't been processed. Remy hair is commonly processed after collection, so it doesn't always meet the definition of raw. That's why She's Happy Hair doesn't carry Remy hair.

Single donor hair comes from one person's head instead of being blended from lots of different people. Having one donor gives the bundle more consistency in texture and cuticle direction. Think about your own hair for a second. Not every strand is the same length, and single donor hair works the same way. That little bit of natural variation is completely normal for real, unaltered hair.

"Drawn" is all about density. Single drawn hair keeps its natural mix of strand lengths, so it's fuller at the top and tapers toward the ends. That taper is totally normal. Double drawn hair gets sorted to remove a lot of the shorter strands, which gives you thicker ends and that full look from top to bottom.

Neither one is automatically better. Double drawn brings the fullness all the way through the ends, and single drawn gives you natural taper and movement. Both can be amazing hair when they're sourced and cared for the right way.

Before you buy premium raw hair, run through these four questions.

1. Source: Where did the hair come from? A country name is a great start, and the full sourcing story tells you even more.

2. Donor: Is it single donor or collected from multiple donors?

3. Cuticle: Are the cuticles intact and running in one direction?

4. Processing: Has the hair been colored, acid-treated, silicone coated, steam textured, or chemically altered?

If the hair is already in your hands, try these checks too:

• Look for natural variation. Raw hair can vary a little in color, wave pattern, and strand length from bundle to bundle.

• Do a wash test. Washing removes surface coatings, so raw hair should look and feel pretty much the same afterward. If the hair turns dull or rough after a wash, it may have been coated.

• Check the ends. A natural taper on single-drawn hair is exactly what you want to see.

• Feel it from root to tip. Hair with aligned cuticles feels smooth sliding down and slightly textured sliding up.

• Try a burn test on a few strands. Human hair burns to a fine ash and smells like burning hair. This confirms you have human hair, and the checks above help confirm it's raw.

Some searches for black hair grades or African American hair grades are really about curl patterns, and that's a whole different conversation. Hair texture types like 3C, 4A, 4B, and 4C describe the shape of your curls or coils. They're a separate system from bundle grades like 10A or 12A, and they have nothing to do with quality. To find the bundle texture that matches your natural pattern, check out our Hair Extension Textures Guide. If you have Type 3 or Type 4 hair, our guide on how to blend hair extensions will help you get a seamless install.

Hair grades are a handy shorthand, and now you know how to look past the number. Focus on the source, the donor, the cuticle, and the processing, and you'll spot quality hair every single time.

Remy hair is human hair collected so the cuticles stay aligned in one direction from root to tip. That alignment keeps the hair smooth, but Remy hair is commonly processed after collection, so it isn't the same as raw hair. At She's Happy Hair, we skip Remy altogether and carry only high-quality raw and virgin human hair.

There's no official best grade because hair grades aren't standardized. For top quality, look for raw hair that hasn't been chemically altered, has intact cuticles, and comes with clear sourcing.

9A hair can definitely be good quality human hair. It's usually sold as mid-range virgin hair and can be a great pick for a budget-friendly install. Since grades aren't standardized, ask the seller whether the hair has been processed and where it was sourced.

Grade 10A is usually sold as high-quality virgin hair. That means hair that hasn't been colored, permed, or bleached, with a soft feel and a healthy shine. For years, 10A was the highest grade most of us ever saw on a listing. It's still a go-to label for high-quality virgin bundles.

It can be! A 12A, 15A, or 16A bundle might be gorgeous, healthy hair, but the number can't prove that on its own. Higher grades popped up as sellers raced for the top of the scale, and there's no shared definition behind them. You'll see a lot of raw Indian hair listed as 12A grade. With raw hair, the source, the donor, and the processing tell you way more than the grade does.

The same grade labels show up on Brazilian, Indian, and other hair origins. The origin tells you where the hair came from and its typical texture. Each seller still sets its own grades, so the same questions about sourcing and processing apply.
