L'Oréal Dia Light 8.1 Light Ash Blonde Hair Color is an acidic demi-permanent gloss color formulated to tone, refresh, and enhance color-treated or sensitized hair without ammonia or lift. Powered by a 1% Hyaluronic Acid complex, it delivers 2x more hydration, up to 82% glossier color, up to 3x less breakage after bleach, and leaves hair 30% more conditioned. The 8.1 shade delivers a cool, neutralized ash finish, perfect for toning highlights, balayage, and refreshing faded color. The acid-gel cream technology seals the cuticle for a vinyl-like finish with ultimate shine. Mix 1:1.5 with DIActivateur Developer and process for 5–20 minutes. Not for grey coverage over 30%. For professional use only.
