Product Overview Highlighted or sensitised coloured hair can sometimes feel coarse & dehydrated. We love this leave-in, softening essence from Kérastase helps to protect & moisturise hair. Benefits Kérastase's micro-emulsion easily penetrates the hair fibre, leaving hair feeling moisturised, supple, soft & controlled. Colour is beautifully deep & stunningly vibrant, whilst the formula provides continuous protection against colour fading & frizz. Key Technology Kérastase's revolutionary Aqua-Ionic System fills the fibre with active emollient & shine-enhancing ingredients, whilst locking out humidity. Our UV filter & Vitamin E limit damage caused by free-radicals & protect the colour from photo-oxidation.
