This is a permanent hair dye that gives the hair a deep black color with an elegant bluish undertone. It effectively covers grey hair and delivers a uniform, long-lasting result from root to tip. The caring formula helps maintain the hair’s softness, smoothness, and shine throughout the coloring process. To use, mix the color cream tube (50 ml) with the oxidant bottle (50 ml), apply the mixture to dry, unwashed hair, and leave it on for 30–40 minutes depending on the desired effect. Then rinse thoroughly with warm water and apply the included conditioner (15 ml), which nourishes the hair and helps lock in the color.
