Cotril Icy Blond Extra Purple Shampoo is specifically formulated to counteract unwanted yellow and brassy tones in blonde, bleached, or gray hair. This specialized cleansing treatment works by depositing cool violet pigments to gently neutralize warm reflections, maintaining a bright, cool, and luminous blonde result. Regular use helps preserve the integrity of cool tones between salon visits, leaving hair clean, soft, and vibrant. It is ideal for those seeking to enhance silver or platinum shades while providing necessary care for treated hair.
