Hair colour protection involves using products and practices to maintain the vibrancy and longevity of dyed hair. These products typically contain UV filters and antioxidants that shield hair from sun damage and environmental stressors, preventing colour fading or oxidation. Additionally, colour-protecting products help to nourish and moisturise coloured hair, preserving its shine and preventing dullness. Regular touch-ups, limiting heat styling, and minimising exposure to harsh chemicals also aid in colour preservation.

The Blond Absolu range by Kérastase is designed specifically for blonde hair, whether natural or chemically treated. It addresses common concerns such as brassiness, dullness, and damage often associated with blonde hair. The range includes products like the Bain Ultra-Violet Purple Shampoo and Cicaflash Conditioner, which hydrate, strengthen, and illuminate blonde strands while neutralising unwanted yellow undertones, maintaining a luminous, cool blonde colour.

The Kérastase Bain Ultra-Violet Purple Shampoo typically contains a combination of purple pigments and caring agents. It is enriched with violet and blue pigments, and ultraviolet neutralisers that counteract unwanted yellow and brassy tones in blonde, bleached, or pre-lightened hair. This shampoo also includes ingredients like hyaluronic acid, edelweiss flower extract, and antioxidants to hydrate, nourish, and protect the hair while neutralising warm tones for a cooler, more vibrant blonde colour.

The Blond Absolu range from Kérastase offers ideal colored hair products for illuminating and healing hair. Specifically, the Bain Ultra-Violet Purple Shampoo and Cicaflash conditioner hydrate and illuminate blonde strands. They also neutralise brassiness and nourish the hair, leaving it luminous, strengthened, and revitalised, enhancing both colour and health.

Using Kérastase Blond Absolu colour-protecting products is quite simple. Begin with wet hair. Apply the Bain Ultra-Violet Purple Shampoo, lather, and massage into the scalp. Leave on for at least two minutes to a maximum of five minutes, depending on the desired degree of neutralisation, then rinse thoroughly. Follow it up with the Cicaflash conditioner, applying it evenly through mid-lengths and ends on towel-dried hair. Leave the conditioner on for three to five minutes and rinse well to neutralise brassiness and enhance blonde tones.
