Pastel hair color? Great idea! The Joanna brand has created 4 pastel shades for hair coloring, which you can cover all your hair or just the ends. The color stays on the hair for a minimum of 10 washes and is best seen on blond and bleached hair. Thanks to the fact that the shampoo is in the sachet, it is super easy and comfortable to use. In addition, it does not contain ammonia and oxidant.
