My daughter recently got extensions. She knew it was Remy hair, but was told it was high quality. However, in just a couple weeks time it has started to snarl and knot up just during the course of her day to the point that it looks almost matted. I know I have seen information about this happening on here before, but I can't remember the particulars. I want to help her deal with her vendor, but I need to know what would cause the hair to do this. Any insights you ladies can provide would be greatly appreciated.
