Kérastase Blond Absolu Masque Ultra-Violet: Anti-Brass Blonde Perfecting Purple Masque 200ml

Kérastase Blond Absolu Masque Ultra-Violet is a rich purple hair mask designed to care for lightened, highlighted, cool blonde or grey hair that’s prone to brassiness. The creamy texture is infused with hyaluronic acid, edelweiss flower and ultra-violet pigments to help neutralise unwanted yellow tones while delivering comforting hydration. Hair is left feeling softer and smoother, with a cooler, more even-looking blonde and a healthy-looking shine.

Use this mask after shampooing as an occasional or regular treatment, depending on how quickly brassiness appears in the hair. It fits easily into a blonde care routine alongside a gentle or violet shampoo, offering a more targeted boost of tone correction when needed. The formula works to nourish sensitised lengths that have been lightened or bleached, helping them feel more supple and easier to manage while supporting a luminous, salon-fresh finish between colour appointments.

How to use
How to Use:
Start with freshly washed hair and gently towel-dry to remove excess water. Apply Kérastase Blond Absolu Masque Ultra-Violet to the lengths and ends, avoiding the roots. Distribute evenly through the hair and leave on for around 3–5 minutes, or up to 10 minutes if stronger neutralisation is desired. Add a little water, emulsify, then rinse thoroughly.

Frequency:
Use once a week or as often as needed to help control brassiness, following the guidance on the product packaging or your hairdresser’s recommendation.

Application Technique:
Work the mask through sections of hair using your fingers or a wide-tooth comb to ensure even coverage. Rinse until the water runs clear before styling as usual.

Best Practices:
Apply to clean, shampooed hair for best results and adjust the leave-on time according to how cool you’d like your blonde to look. Follow with your preferred styling products and use a heat protectant before blow-drying.

Safety Tips:
For external use only. Avoid contact with eyes; if this occurs, rinse immediately with plenty of water. Discontinue use if irritation occurs and keep out of reach of children.
