Over time natural blonde, bleached or lightened hair develops annoying yellow reflexes that pollute the colour’s purity. Blonde Maintain is a brightening anti-yellowing shampoo ideal for the treatment and maintenance of all natural, lightened or bleached blond hair. It protects the colour, neutralises unwanted yellow tones and restores shine. The result is a cool blonde effect and a totally purified and illuminated colour. The purple pigment, which gives the texture its typical deep, full-bodied colour, naturally counteracts warm yellow tones by settling between the scales and cuticle of the hair, restoring purity to the colour and bringing it back to life.
