Taken from JA website:

Quote:The basic concept is simple. We have found a way to blend the magic of Hollywood artistry into the real world of everyday Hair Replacement. The results look completely natural viewed from any angle and in any kind of light. EHK was created by combining the finest Hollywood lace, imported virgin European hair, and the best kept design secrets of Erwin Kupitz. Highly detailed attention has been given to the color blend and workmanship. All of the materials, time, special care, and Erwin’s confidential techniques that the major Hollywood stars receive have been incorporated into the EHK design. And now it is available only to J.A. Alternatives clients.

No doubt a lot of marketing hype, but still, they seem to be using the best materials in the market (probably SFS lace, virgin European hair) together with a professional eye.
