Review title is Will not buy again [SEP] Ok so these are very pretty . I have 4 packs in my head in these photos  they are very versatile and dye well . They are thick and good quality tested human hair<br />HOWEVER! There is a major flaw in this system ,every time I brush my hair I loose 3-4 Strands which would not be an issue except the metal at the bead stay put it’s not an install issue it’s a manufacturer error ! The hair slides of the metal u tip and then they are broken and done for.. I will be looking for a new nano tip brand randomly loosing strands and having the remaining metal lost in my hair is super uncomfortable
