Alpine Green Semi-Permanent Hair Colours This deep green is just the shade for those who love to shout about their strong hair colour from the tree-tops. 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.
