Kérastase Blond Absolu Bain Ultra-Violet Anti-Yellow Shampoo 250ml

Bain Ultra-Violet is a professional purple shampoo that neutralizes yellow and orange tones on blonde, bleached, and gray hair. Formulated by Kérastase for those seeking a cool, luminous blonde without compromising hair health.

Who It's For

This treatment was developed for natural blonde, bleached, highlighted, or balayaged hair that tends to turn yellow. It also works on gray hair that develops unwanted warm tones. If you notice orange or brassy reflections a few weeks after coloring, this product will restore your blonde to its original cool shade.

Concrete Benefits

The formula instantly neutralizes warm tones thanks to its high concentration of purple and blue pigments. After the first use, blonde hair appears cooler and brighter. With regular use, it protects color from daily oxidation caused by pollution and UV rays. Hair is 40% softer than with a traditional shampoo, thanks to the filling action of hyaluronic acid, which repairs areas damaged by bleaching.

Technology and Active Ingredients

The formula combines three scientifically tested components. Ultra-concentrated hyaluronic acid penetrates the hair fiber and fills micro-lesions created by chemical treatments, restoring body and strength. Edelweiss flowers provide antioxidants that create a protective shield against external aggressions. Direct ultraviolet pigments (purple and blue) deposit on the cuticle and chemically neutralize yellow and orange tones, according to the principle of complementary color theory.

How to Use

Apply the product to wet hair, distributing it from roots to ends with massaging movements. Leave on for 2-3 minutes to allow the pigments to deposit. This processing time is essential to achieve the neutralizing effect. Rinse thoroughly until the product is completely removed. For very porous or extremely bleached hair, you can alternate it with Bain Lumière as a second shampoo, to balance nourishment and color correction.

Expected Results

From the first application, you will notice a cooler blonde free of yellow tones. After 3-4 uses, the color will stabilize to an ash or platinum shade, depending on the starting base. Hair gains natural shine and is easier to comb. The anti-yellow effect lasts until the next wash, allowing you to maintain the desired tone with 1-2 applications per week.

Frequently Asked Questions

How often should it be used? It depends on your hair's porosity. For very bleached hair, 1-2 times a week. For natural blondes or those with slight lightening, even once every 10 days.

Can it stain hair purple? No, if you follow the recommended processing times. For extremely porous or platinum hair, reduce the time to 1-2 minutes the first few times.

Does it work on brown hair with highlights? Yes, it acts selectively on lightened areas without altering the natural base.

Should it be combined with other products? For optimal results, complete the treatment with the Masque Ultra-Violet once a week and Cicaplasme as a heat protectant before blow-drying.
