The Grade system is a fabricated way of categorizing hair quality. It was created by the Chinese Hair Manufacturers in the hair Industry’s infant years. Originally the grades started at 1A and gradually progressed to 2A, and 3A; then continued on present day where 8A -10A hair is thought to be the best quality hair available. In fact the hair is all the same and has been for all these years. Unfortunately, this was a tactic to manipulate people into thinking the hair is just as good quality as Raw Indian Hair. This same tactic was used in the arrival of Brazilian, Malaysian, Peruvian and Mongolian etc. to the market. These are all names given to hair processed to provide different textures. Hair labeled as such actually comes from all the comb waste of Indian hair and is sold to the Chinese for chemical processing at cheap prices. After chemically processing the hair, It is sold with different names to make the texture of the hair more believable. Normally, when a package is labeled “100% Human Hair” but it tangles, sheds easily and frankly doesn’t last long, this is where the hair is derived from. Since the Hair Extension Industry is not regulated, this practice is how Beauty Supply Stores and other online discount retailers can get away with selling the hair and calling it something it is not. DO NOT be fooled. Invest in Raw Indian or Virgin Human Hair. Just like any other investment, Do your research ladies!
