Atomic Turquoise is a bright, neon, radiant aqua blue hair dye with green undertones. This color can add turquoise tones to virgin, unbleached hair, but looks brightest when hair is lightened to the lightest level 10 blonde. We recommend toning hair that has yellow tones before use to avoid undesired hues. This semi-permanent hair dye formula gradually fades in 4 to 6 weeks because it does not penetrate the cortex of your hair but simply rests on top of the hair shaft. The vegan formula has been specially developed to condition as it colours. These vivid and arresting shades contain no harsh chemicals and are presented in a conditioner base, bringing restorative properties which fill, add moisture, and soften the hair. Tested on celebrities, not animals. Pack size 118ml.
