This Review Title is Worst Extensions EVER and the content is: I am abhorred at the misrepresentation of these extensions. This should be illegal and I think it is. This WAS NOT 100% human hair, I believe it was yak hair. The “Keratin” on the utip is something alien that broke down and melted in my hair.  See pics. The ends melted together the first time I tried to curl it. These are something aimed at Halloween costumes. BUYER BEWARE…DO NOT BUY THIS HAIR!!!!.There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
