I am an essential when Colouring because I activate the Hair Colour when you mix us together. I'm strong, strong enough to Lighten your Natural Hair Colour 3 Shades so I am capable of decent Colour transformations like lightening from 3 Dark Brown to 6.5 Pure Plum or 5 Light Brown to 8.2 Light Beige Blonde or 6 Dark Blonde to 9.3 Light Golden Blonde. You should also know, I love vibrant Hair Colours and I've been created with specific ingredients to bring out the intensity in these Hair Colour Shades.
