Japanese Thermal Straightening

The thermal straightening system that FIX utilizes is the most advanced innovation in hair straightening. This internal structuring system permanently straightens excessively curly or wavy hair while leaving it in optimum condition.

Most straightening products use harsh chemicals, which can leave the hair dry and lifeless. Less caustic products fail to straighten the hair permanently. Our thermal straightening system is a unique approach, which provides internal conditioning and beneficial protection through its combination of Vitamin B5, Soy Proteins, Wheat Proteins and Keratin Amino Acids. The system is then used with a Paul Mitchell smoothing iron, resulting in permanently straightened hair that is smooth, shiny and healthy.
