What Is Hair Extension Grade?

Hair extension grades refer to a system used to categorize the quality of hair extensions. This grading system, often seen as numbers like 5A, 6A, 7A, 8A, 9A, and 10A, is intended to help consumers understand the quality and durability of the hair they are purchasing.

Hair extensions that are graded 5A and below are lower quality hair extensions and are typically the cheapest. Those may not last long and usually cannot withstand heat or dyeing well.

6A and 7A grade offers medium quality hair extensions. Brands that offer 8A, 9A and 10A grades usually provide 100% virgin human hair from a single donor.

Here’s a table that provides a comparative view between the hair grades from 6A to 10A in terms of quality, dye capability, lifespan with care, and thickness and strength.

Grade Heat Styling Upto
Bleach Capability Upto Lifespan with Care Thickness and Strength
6A 100 – 120 Dark blonde 3 – 6 months Standard
7A 150 – 200 Medium blonde 8 months Better than 6A
8A 220 – 260 Platinum blonde 1 Year Thick
9A 250 – 300 Any level 2 Year+ Thicker
10A 300 – 350 Any level 2 Year + Thickest

However, the grading system is not standardized or universal and can vary between suppliers. As formal regulation doesn’t exist, it can be hard to tell if the hair you are purchasing online has been marked correctly without being able to touch it.

This is where reviews and blog forums can come in handy. Going with a well-known brand will be your best bet when choosing between 6A-10A hair.

Choosing Your Ideal Hair Grade

6A Hair Grade

6A hair is the best budget choice that won’t sacrifice too much quality in the hair. It can last up to a year with proper care. When cared for properly, it will last anywhere from 3-6 months or just under a year if hair remains virgin.  

You can also choose grade 6A Benehair Human Hair Bundle which can be straightened, curled, dyed and bleached. It’s an affordable option and also there are different size, color and style available for you.

Its relatively porous nature makes it ideal for coloring hair upto dark blonde. However, read the bleaching, dyeing and styling instructions carefully.

You will need 3 bundle to fix one head and 4 bundle if it is over 18 inch. The extension can not withstand temperature over 120 Fahrenheit so if you want an extension that is suitable for rough styling we will advice you to choose a higher grade hair extension.

7A Hair Grade

A higher quality than 6A, this hair can be dyed to a platinum blonde and can last a bit longer with proper maintenance. Still, with this hair, the cuticle of the hair shaft is solid and all face in the same direction.

9A hair is very similar to 8A hair in terms of offering and ability to be colored to a white blonde hue. However, it can last a little longer than its lower-grade counterparts, with a lifetime of up to 2 years or slightly longer if perfectly cared for.

Coloring 9A hair will decrease its quality and mean that it may not last as long as other totally virgin hair with this grade. 

9A hair also has a healthy shaft, indicating that the hair in the bundles you receive is all long and strong. Expect less tangles and easy maintenance with 9A hair. You can opt for 9A Grade Brazilian Virgin Hair for longevity and heat styling.

Regarding quality, 10A hair is the most expensive yet the highest quality virgin, unprocessed hair on the market. This hair is the thickest and fullest, with the healthiest shaft all the way to the ends of the hair. The hair in each packet is long and hand-selected, so all hair is the same length. 

Without color processing, 10A hair can last more than 2 years. If you want to purchase 10A hair, expect minimal maintenance and hair that is difficult to mat or tangle up. 

You can get this premium 10A grade Perstar Wave Bundles and enjoy your stunning hairstyle for an extended period. However, the given length of these wave bundles is measured when the hair is straightened so you will have to choose accordingly.

While the grade of hair certainly matters but sometimes it is just marketing strategy. All hair from 6A and beyond is of fairly decent quality and will ensure that your weave, wig, or extensions look fantastic. So, think about the color you desire, the texture you crave, and the budget before hair extension grades.
