Ms. Yuko Yamashita

The people who make the Yuko Hair Straightening System offer this information about their product.

Yuko Hair Straightening System smooths curly, dry, unruly hair permanently with a revolutionary straightening system that uses heat to restructure the hair’s protein bond. The result is smooth, sleek, shiny, straight, regenerated (repaired”> hair!

The protein-based professional Yuko System uses a specially-designed, patented heat iron set at over 300 degrees to seal in moisture once the cystine bone in the hair is cut off, allowing hair to be molded into any shape. Heat consolidates the straightening process – repairing and regenerating hair. The shine and softness are evident. Salon professionals and the customer both love the system’s results.

Ms. Yuko, who created the system in 1996 with the intent to create a non-coating, straightening system that uses the heat oxidation process to seal in and rebuild hair from the inside out. One of the Yuko steps includes using shark oil on hair and also using steam instead of direct heat to condition hair.

Both an unconventional idea and a breakthrough in the art of hair straightening, the Yuko Straightening System actually uses the hair’s small amount of “living body electricity” to cut off the hair’s cystine bone, reshaping it to appear straight. This goes against the notion that straightened hair is damaged hair: the result is hair that can breathe from a lack of coating, and a hair shaft that is rejuvenated for the first time. If desired, the Yuko process can be reversed to obtain natural curls again.

Yuko Hair Straightening System FAQ

Q: How many touch-ups do you need and how long does the process take?!

A: Expect to have the process done at least twice a year. Long hair takes four and a half hours to be processed. Short hair is about three hours.

Article continues after video.

Q: How long does the Yuko straightening last?

A: Once the hair is processed it is permanently straightened. There are NO traditional waxes used, therefore time does not “wear down” the process. The straightening comes from a re-structured protein bond inside the hair shaft.

Q: What if I want to wear my hair in a curly style or what my old curls back?!

A: Your hair will respond to any curling iron. If you want to grow out your hair, the Yuko System can be reprocessed with new solutions to bring back curly hair!

Q: What is the youngest age a person can use the Yuko System?

A: It is safe for a child as young as twelve years old to use the process.

Q: Can senior citizens use the Yuko System?

A: YES! The system is processed the same on aged hair but performs just as beautifully.

Q: Is it safe to use this revolutionary hair straightening system?

A: The system has been tested in three continents: Asia, Europe and the USA. It is safe for children over age 5 and for seniors as well!
