I purchased 3 bundles of brazilian straight 12/14/16 from Nala Queen on Aliexpress. The hair had been colored because a ton of black dye came out when washing. The hair was dirty, it had lent, and various colored threads. There was also a noticeable chemical odor that lingered after washing. I did get half of my money back because I was getting ready to go out of town and did not have time to find more hair. I get a little shedding, but that could be from the colored ends.
HTH - sorry for the giant pics
