The lace material used in the base construction of the EHK is acquired from a special source. Erwin Kupitz has used this confidential source for his own Hollywood movie creations for many years. And now he has incorporated it into the EHK exclusive design. The material is treated in a way so that it accepts various bonding methods easily along with providing an invisible appearance against the scalp. It is the lightest, thinnest, yet remarkably strong material that we have ever used in a hair replacement.
