We serve you with decades of manufacturing experience and proven technology.

Since 1984, we have manufactured and exported wigs, hairpieces, and hair materials,
while also developing the machines, process systems, and chemical products used to produce them.

Alongside production, we have conducted extensive hands-on training worldwide,
from large-scale factory programs involving thousands of workers
to customized one-to-one training for professionals, company trainees, and complete beginners
from over 30 countries.

Through continuous collaboration with global buyers and partners,
real market feedback flows back into our development process—
enabling us to refine machines, improve chemical formulations, and create practical, scalable,
and commercially viable solutions.

This integration of manufacturing, development, education, and feedback
is what we define as Integrated Wig Science.
At the beginning of 1970's, our dyeing technician, under the guidance of a professor of a textile dyeing university developed the dyeing method for raw human hair as the first dyeing technician in Korea.

And he had been upgrading the technology while working for processing & dyeing raw human hair (over 6,000 tons) of Korean human hair products factories exporting to the world before before he joined John Korea's Training course as a trainer in 2001.

Between 1980 ~ 1990, more than 80% of hair products in the world market were produced in Korea.
1985, 95% of hair products sold in Japan were made in Korea; 85% of hair products in USA were made in Korea.)
There were 7 Korean hair procressing & coloring factories in 1980's that processed raw human hair for Korean human hair product factories.
