YUKO Hair Straightening, also known as Japanese hair straightening, is the world renowned U.S. patented method recognized as the leading brand of chemical hair straightening that gives you low maintenance, shiny, hassle-free straight hair. No matter how curly or unruly your hair is, YUKO will create the results you’ve alwayswanted. All after pictures are finger dried by hand with a blow dryer, no round brush. That is how the hair will look every time you wash and finger blow dry it. Blow drying time is cut in half since the cuticle is completely restructured. Only after care is using sulfate free shampoo and conditioner and not over shampooing. Also drying the hair 100% every time you wash will keep the cuticle smooth and ensure it staying healthy and straight.
