When I began my hair business 12 years ago, the highest hair grade is 4A, and now the highest is 10A and even 10A+, I have to spend a lot of time explaining it when my clients ask for the 10A hair.

Which is better 10a or 12a hair?
First things first, let’s get to the bottom of these mysterious hair grades. The truth is, they’re more about marketing than actual quality standards. Vendors often use grades like 7A, 8A, 9A, and 10A to differentiate prices, even when the hair quality doesn’t differ significantly. These labels aim to suggest a higher quality tier; however, they’re not standardized across the industry. That means a 10A from one vendor could be quite different from another. It’s a bit like trying to buy a mystery prize, isn’t it? It’s essential to keep this in mind before buying into the numbers game.
The idea was simple: convince shoppers the higher the number and the more A’s, the better the hair.
In fact,virgin, Remy, and raw hair are more significant indicators of quality than a 10A or 12A label.

What is the best bundle hair to buy?
Let’s get to the real meat: what truly makes one bundle better (and pricier) than another?
The top 3 factors for what makes a bundles cost higher or lower.
One of the top factors is the long strands that are in the hair bundle, that’s one major factor.Within each bundle, some strands are long, others are shorter. The more long strands you have, the thicker and fuller your hair will look all the way to the tips.
There are two simple ways to test.
If you actually run your hands through it, it’s a better quality when you feel it is a little bit more consistent all the way through, it actually has a lot more longer strands.
If the one will feel a little bit thicker at the top and then very quickly will thin out, it’s obviously not a good quality.
You can also do something like this where you can grab the bottom and you can shake it and you can see how many short strands come out, that’s a little technique we use just to do a quick check.
That having the longer strands in the bundle is going to make the bundle cost more generally you’re going to have a little bit better result, you are going to have less flyways.
What is the best bundle hair to buy?
The next factor is the actual weight of the bundle, so most bundles are sold around 100 grams, some companies will you know it could be anywhere from 95 to 105.It’s not an exact science sometimes it really depends on the manufacturing facility. So you have to really think about how much weight is.
Most hair bundles are sold at or near 100 grams—about a big handful. But sneaky suppliers might skim off a few grams per bundle. That cheaper price? You might just be getting less hair.
The last factor is fillers.
These sneaky additions, like plastic or synthetic fibers, are meant to boost the weight and volume of your purchase but instead, compromise quality.
It’s usually lower-quality, leftover hair added to bulk up a bundle without you noticing. These strands are prone to tangling, matting, and breakage. Especially in virgin hair (vs. raw), filler can sneak in. A trustworthy supplier takes the time to sort out fillers and keep things pure.

Conclusion
When searching for high-quality hair, discussing directly with your vendor is key. Skip the talk about the grades and jump straight into asking the tough questions: Is the hair 100% virgin or raw? Are there any fillers or chemicals involved? Will it hold up to coloring and styling?
Focus on real quality, ask good questions, and pick what feels right for your lifestyle, look, and budget. Happy hair shopping—you’ve got this!
