SYOSS permanent hair colors, designed for professional results, ensure that your hair color looks and feels vibrant for a long time. The color cream, with rich color pigments and keratin, penetrates deep into the hair fiber to guarantee up to 100 days of professional color intensity and up to 100% gray coverage. The intensive care mask with keratin strengthens the hair intensively from within and smoothes the hair surface: the color pigments are well captured and reveal the most vibrant and rich colors of SYOSS.
