You are excited to receive your new wig. However, when you take it out of the box, you may be concerned that it looks differently than its online picture. The wig may look “flat” or has kinks in the fiber. There are a few terms in the wig industry that define this: "box hair," "cold crimp" and “cold set.” A wig develops cold set during storage or shipping where fluctuations in temperature can alter the fibers' shape. Thus, the wig may have warped areas or bumps that you didn’t expect.
