As an expert in hair products, I recommend the Wella Koleston 7 Supreme Hair Dye 9/1 Special Light Ash Blonde for its innovative formula that provides complete gray coverage, deep hydration, and intense color result with a radiant shine. This color cream has a patented formula to prevent damage and boost the seven signs of healthy hair. The package also includes a conditioning treatment and a color enhancer for vibrant, luminous hair.
