Tresemme Ash Blonde Colour Enhancing Hair Mask is the solution for keeping your hair colour looking beautiful in between visits to the salon. Suitable for natural or dyed hair, highlights, balayage and ombre, our professional-quality formula with effective colour pigments reduces brassy and yellow tones refreshing your colour without damaging hair. The colour pigments adhere to the surface of the hair instead of giving a chemical reaction in the core. In just a few minutes, this nourishing mask, enriched with UV filter and argan oil, provides a vibrant colour boost and a glossy shine in between colourings or salon visits. This hair mask, made with no ammonia or peroxide, is suitable for daily use and meant to be used on the same hair tone to enhance it. The effect remains visible for 2 to 3 washes. How to use: Wash your hair with your favourite Tresemme shampoo. Evenly distribute the mask on damp hair focusing on mid-lengths to tips. Leave in for 3 to 5 minutes then rinse thoroughly. For a more intense colour conditioning, leave in for up to 15 minutes. The result obtained after usage depends on your original hair colour and the condition of your hair. With this colouring mask, it is not possible to colour your hair lighter than your original colour. Does not give grey coverage.
