Introducing our best-selling pink hair dye! Pinkissimo is a semi-permanent hot pink hair dye which has been formulated to create perfect pink hair. Marilyn Monroe said, “Some like it hot”, and she was not wrong. For the best results, we recommend lightening your hair to level 9 or 10 (blonde) before use. It is also suitable for level 8 (light brown), however, results will only be tonal.
