Tecna Colour Keeper Nourishing Drops are formulated with an anti-fading acid action to protect and prolong the vibrancy of colored hair. These drops actively work to seal the cuticle, reducing color washout after washing and environmental exposure. Ideal for frequent color-treated hair maintenance, this treatment smooths the hair surface, enhancing shine and manageability without weighing the hair down. Integrate this oil into your daily or regular hair care routine for sustained color brilliance.
