Ideal for highlighted, blonde or colour-treated locks, the Balmain Hair Ash Toner is enriched with deep violet hues to minimise unwanted brassy tones. Infused with Silk Protein & Argan Elixir, the clarifying, leave-in mist neutralises yellowness & restores a permanent ash tone with a fresh, cool finish. Brightens grey hair & enhances natural shine, whilst nourishing & softening strands from root to tip. Can be used on human hair extensions.
