What does the addition of Q10, vitamin C, and oleic acid do for the hair during and after coloring with this product? — Hair Dye "Dark Mahogany" 5.5, 130 ml – Premium Fashion Color Rubella

These three ingredients are included as 'conditioning and protective helpers,' each with a distinct role based on their common use in hair care. Q10 (Coenzyme Q10) and Vitamin C (Ascorbic Acid) are primarily valued for their antioxidant properties. In the context of oxidative hair color, they help defend the hair from additional oxidative stress during the development process, which can contribute to the hair looking livelier and less dull afterwards. Oleic acid is a fatty acid known for its emollient properties. It works on the hair's surface to soften it and improve slip, which can make freshly colored hair feel smoother to the touch and appear shinier. Together, they are part of the formula's aim to provide a more polished, glossy finish and a better post-color feel in one step.
