Cotton has been spun, woven and dyed since prehistoric times. Recognizing cotton fibers' unique properties, Mr. Shu Uemura singled them out for the creation of his legacy. The inherent strength, elasticity and softness of cotton fibers help this product to provide flexible definition and create a soft touch. The Japanese word 'uzu' which translates to 'swirl' pays homage to the cotton fiber's elementary state in the blossom. Safe on color-treated hair.
