When you shopping hair wigs online website, you can find most of the companies use the grade 5A 6A 7A or 8A to distinguish the hair, then how to grade the different hair wigs.

Now, there are many different types of hair wigs, the grades (5A, 6A, 7A, 8A) all were created by vendors in China, as to explain to their customers the quality of their hair wigs. Currently, now there is not have a "Universal Standard" for human hair wigs grading, do not have a standard hair wigs grades that you can pull up and it be accurate.

However, there are some factors that we consider when grading for virgin hair extensions:

Wefts: Single stitch or double stitch? Double stitch wefts should reduce shedding.

Weight: The standard weight of sew-in hair bundles are 100 grams or about 3.5 oz. Is the bundle cheaper because it weighs less?

Remy or Non-Remy: You want remy hair with the cuticles facing the same direction to reduce chances of tangling.

Single Donor or Multiple: Single Donor hair really only matters for a few types of hair including Indian Temple hair or possibly a unique gray hair. Is it necessary? 99.9% of the time we would say no. Some companies “claim” the hair bundle is from a single donor but I would not pay extra for it.

Single or Double Drawn: Most all human hair sold in the USA market is single drawn hair. The cost to produce a double drawn bundle is much higher because of the shackling process of removing the shorter hairs is much more expensive during the manufacturing process. Expect to pay more for a bundle of human hair that has long hairs all the way to the tips.

Color: Can you color the hair? The best quality virgin hair will lift all the way to a #613 Blonde. If you are not coloring the hair you might consider buying a less expensive option if available.

Styling: Human Hair extensions generally should not have an issue styling.

It is important you know exactly what you are buying and selling to your clients.
