Schwarzkopf Igora Vibrance Kit 4-99 Brown Violet Extra is an ammonia-free tint color. When you mix it with beize, you get a high-quality home color. The hair color is soft, easy to mix and rinse off. A color result that is up to 70% more shiny than uncolored hair. The color lasts up to 25 hair washes. Use the color for full color or just refresh. Please note that this is ONLY the tint color itself, and you must therefore already have 1.3 - 3% beize at home to be able to use it. NOTE: The color result depends on your natural hair color and the color basis. This shade is recommended for brown and light brown hair.
