KERASTASE Blond Absolu Bain Ultra-Violet Shampoo - Neutralizes

In this review of KERASTASE Blond Absolu Bain Ultra-Violet Shampoo the bottom line is clear: this is a targeted purple shampoo for anyone who wants to neutralize warm, brassy undertones while keeping hair feeling soft and looking shiny. The product stands out for its blend of blue and violet pigments that correct gold tones without leaving an obvious cast. Reviewers praise its scent, quality and the healthy finish it gives to blonde and highlighted hair, though some users report mixed feelings about value and occasional dryness on already fragile strands.

Key Features

• Neutralizing pigments: Blue and violet pigments work together to counteract yellow and gold undertones for cooler-looking blonde.
• Restores shine: Formulation helps improve light reflection so hair appears glossier after use.
• Softness boost: Leaves hair feeling smoother and more manageable compared with many clarifying purple shampoos.
• Signature scent: Customers note an appealing fragrance that makes routine washing feel more luxurious.
• Color maintenance: Helps maintain highlights and blonde tones between salon visits when used as directed.

Who It's For

This shampoo is best suited to people with natural blonde, color-treated blonde, bleached hair, or highlights who want to neutralize unwanted brassiness and keep tones cooler. It will appeal to anyone who prefers a product that leaves hair feeling soft and looking noticeably shinier after rinsing.

Those with very dry, porous, or damaged hair should use it cautiously and follow with a hydrating conditioner or mask; some users reported that it can be drying on fragile lengths. If you need a daily gentle cleanser rather than a tone-correcting shampoo, a milder, non-violet alternative may be a better choice.

• Improves shine and leaves hair feeling soft compared to many toning shampoos.
