Yuko Hair Straightening was created in Japan in 1996 by Yuko Yamashita, a hair stylist and salon owner who wanted to make people's lives easier when it came to hair care. This special straightening process utilises collagen, keratin and silk proteins which penetrate the hair follicle. A hot iron promotes heat oxidisation to leave hair smooth, radiant and manageable with minimal effort. Yuko is the original and leading hair straightening system. The hair that has been straightened will remain straight, your roots will grow out in the normal way.  As well as straightening your hair, Yuko also de-volumises and gives fantastic shine and manageability.Typically you would do your roots between 6 and 12 months after your first service, depending on hair type, style and growth rate.
