Hello I am writing a review because I purchased this hair. I purchased 3 packs for a full sew-in but only needed two. While I am loving this hair I can only give it 3 stars because one of my packs must have been a bad batch. My stylist put in 2 packs originally and then within hours one pack was matted so bad I could not comb through it. I had to go back to the salon the next day and have that part removed and add the other pack I had. Now since I got two good packs in, I love the hair. It does not shed much, it's very low maintenance, and it does not tangle much at all. I have contacted customer service to see if they would help me out because this hair way too expensive to have a 1 in 3 chance of getting a good pack of hair. I have included pictures of the back of my hair about 3 hours after it was put in and a side by side pic of the hair that was removed and the hair that I replaced it with. I am hoping customer service will help me resolve this issue.
