Put simply, the difference between bundle hair and packaged hair, is the quality. A bundle is made from the cutting the gathered ponytail of one donor. All hairs are the same structure, all placed on the weft in the direction of growth which prevents tangling.
Our hair is double drawn which means all of the hairs are the same length, which prevents shedding. With packaged hair, the hairs on a weft come from many donors. The hairs are not the same length or placed in the direction of growth and this leads to shedding and tangling.
