Kanekalon, a lighter and softer hair used globally for synthetic wigs and extensions, consists of a type of synthetic fiber known as modacrylic fiber. These fibers are modified acrylic fibers that stem from acrylonitriles and vinyl chloride.
Kanekalon's feel closely resembles that of human and animal hair. The modacrylic fiber it is made out of is often creamy or white and comes in a variety of lengths, crimp levels and deniers. It also often contains an array of shrinking potentials. As the majority of modacrylic fiber contains similar temperatures to boiling water and steam, the majority is easy to seal with steam and related objects. However, some dyes contain heat-resistant properties, requiring higher temperatures to accurately seal the hair.
