Japan based Yuko System's patented Thermal Reconditioning process based upon the principles of restructuring hair’s protein bonds. This curl busting process has taken the hair world by storm. This natural cornstarch-based hair relaxing system utilizes a more gentle form of ammonium thyoglycolate free of the traditional relaxing waxes or lyes along with special straightening irons. Developed in 1996 by Ms. Yuko, the system was designed to create a non-coating, straightening system that uses the heat oxidation process to seal in and rebuild hair from the inside out through a combination of patented chemicals and irons that reach 356 degrees to achieve sleek and silky straightness.
