目前市场上有部分厂家生产的假发是80%真发混合20%高温丝或者80%真发加20%蛋白丝，那么这种混合的发丝有什么优势和劣势呢？
1、混合发丝的优势
假发为了打造更多夸张的造型，仅仅依靠真发发丝是不能完成的，因为头发有弹性，有张力，所以在定性方面比较差。而且高温丝只能在低温180度定型。所以很多夸张的发型基本都是化纤高温的。而化纤高温丝经过定型后，发丝表面会有裂痕，再次使用就会打结，所以，纯高温丝的假发一般都是一次性的。通过混合80%真发，就能到达更好的定型左右，防止发型变形。通过扎光处理，发丝如真发的颜色一样有光泽，很难分辨。
Wig in order to create more exaggerated form, relying solely on real hair hair is not done, because the hair elastic, there is tension, so in the qualitative aspects of relatively poor. High temperature wire and only at a low temperature setting of 180 degrees. So many exaggerated hairstyles are basically synthetic high temperatures. After high-temperature wire and fiber stereotypes,there will be cracks in the surface of the hair, it will be used again knotted, so pure high temperature wire wig are generally disposable. By mixing 80% real hair, you can reach a better stereotypes about preventing hair deformation. By rolling light treatment, such as hair color, like real hair shiny, hard to tell.
2、混合发丝的劣势
化纤高温丝，无法进行染色。所以通常配比的化纤是生产的原丝染好的，不能再进行上色。有些高温丝，不能用染膏和烫发药水，经过试验，加了高温丝或者蛋白丝的假发，遇上烫发或者染发药水，其发丝材质如煮了的面条一样脆弱。当然化纤高温丝比真发发丝要便宜很多，也能降低成本。
High temperature fiber yarn can not be dyed. Therefore, the ratio of the fiber is usually produced raw silk dyed good, can no longer be painted. Some high-temperature wire, can not perm hair color cream and syrup, after testing, plus the high temperature silk or silk protein wig, met perm or hair potions, their hair as fragile materials such as boiled noodles. Of course, the high temperature silk fiber hair than real hair is much cheaper, but also to reduce costs.
