Atlantic Blue Semi-Permanent Hair Colours Taking inspo from the depths of the ocean, Atlantic Blue recreates the shimmering tones of the open seas. This colour transforms locks into beautiful rolling waves. 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.
