Dark Tulip Semi-Permanent Hair Colours A twist on tulip: this darker colour gives hair a rich, wine-like shine. With deep shades of purple and red, it’s perfect for those who want coverage on almost any base. For the most vivid results, we recommend applying to pre-lightened hair. The colour on the pot is a simulation of the colour on a level 10. Soft, silky hair never goes out of style. That’s why all our colours contain a conditioning formula that nourishes hair from first application.
