What is Hair Grading System?

when shopping arround, you may notice that many vendors use the (5A, 6A, 7A, 8A, 9A, 10A) grading system to describe their hair product. At the very begining it was created  by manufacturers in China as an easy way to distinguish the different level hair quality. The fact is that there is not a “international Standard” for human hair extension grading. There is not a standard hair grades chart that you can pull up and it be accurate. Factory may consider some factors to grading for virgin hair extensions:

origin: Some consider 7A as the Malaysian hair, 8A for the Brazilian hair, and RAW for the Vietnamese hair or Indian Hair. (It depends on the vendors' rules)

Hair material: As we all know human hair including virgin hair, remy hair and non-remy hair, usually virgin hair is regard as the higher grade.

Weight: The standard weight of sew-in hair bundles are 100 grams or about 3.5 oz. Is hair grade lower because of its weighs less ? For example: defined 95grams bundle as 7A hair, 100grams as 8A hair, etc.

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.

The proportion of longest hair: Which refer to the fullness of the bundle, hair with less short hair is consider as higher grade. 

Color: How light color can the hair lift to?  The best quality virgin hair will lift all the way to a #613 Blonde. Remy hair lift to darker #27. If you don't have high demand for bleaching or coloring you don't have to choose the most expensive one. 

All these factors above can be a basic consideration when vendors defined the hair grade and different vendors could have different rules while give a number grade. What one vendor consider as 7A hair extensions could be a 9A from another company, so while you are comparing hair quality you should only compare between one vendor.  Many people still don't know that there is no standard on the hair grade and they just compare the grade when choose a vendor and that's why so many vendors try to upgrade the hair even to 12A now.
