Whats the Difference between Human Hair Grades- 7A 8A 9A ?

- Nov 03, 2017-

Before we get to know the difference between human hair grades-7A 8A 9A, we can know the cuticle hair extensions at first. We start with the definition of "hair cuticle".

According to Wikipedia 

The hair cuticle is the outermost part of the hair shaft. It is formed from dead cells, overlapping in layers, which form scales that give the hair shaft strength and provide protection for it. Although the cuticle is the outermost layer of the hair, it does not give the hair its color because it has no melanin, which is the pigment responsible; the color of a person's hair depends on what type of melanin they have, which is found in the cortex.

Human hair also has different grades according to the state of the hair cuticle.

As we all know, the different factory has a different quality standard to define different hair grade so that there are too many different price range and quality. Even some suppliers use low-quality hair as high-grade hair. so we should see hair quality first rather than regarding their hair grade as important only.

Our factory also have a standard about the hair grade. Now we explain these grades systematically so you can be more clear when you choose them.

5A: Non-Remy hair, suitable for low-class market.

6A: Remy hair, and cuticle towards the same direction.

6A+: Thicker hair than 6A at the bottom, that means 6A has more short hair mixed in the bundle

7A: Same quality as 6A, and 6A+, but thicker hair than 6A and 6a+

7A+: Same quality as above hair, but very slightly short hair in the bundles.

8A: Virgin human hair just from one head

9A: Virgin human hair just from one head, but better quality than 8A.

(For example, this is a 100% human hair weft of 7A grade. )

From the above, we can see it is really different between the grades, so when people need to purchase hair extensions, they should see hair quality first instead of just focusing on the grades.
