Rejuvenate your colour with Kérastase Blond Absolu Bain Lumiere Shampoo a gentle, nourishing cleanser for highlighted, grey or lightened hair. Kérastase’s unique formula intensely hydrates hair while removing impurities and build-up to reveal a healthier-looking, more illuminated blonde. Kérastase’s Blond Absolu Bain Lumiere products are specially formulated for colour-treated blondes. This luxurious formula gently cleanses hair while keeping it healthy and hydrated. Combining scientifically formulated compounds with powerful botanicals, this product helps keep lightened hair looking healthy. First, ultra-concentrated hyaluronic acid strengthens hair from within. This compound is complemented by edelweiss flower, whose natural antioxidants protect hair from day-to-day damage and soften sensitised hair fibres. For best results, use this shampoo as part of your daily hair-care routine. Apply a ten pence piece-sized amount to wet hair and massage the scalp through to the ends. Rinse thoroughly and if desired, repeat. This second wash will create a foamier wash that will cleanse hair all the way to the ends. Alternatively, alternate this product with Bain Ultra-Violet for a gentler cleanse while neutralising brassiness or yellow tones.
