Repeated washing, sun exposure, pollution and external aggressions can make colour treated hair more sensitive. With time colour fades, losing its shine and intensity. The secret to colour protection is a creamier formula which is easier to rinse out. The L'Oréal Laboratories have created a formula which acts on 3 Dimensions of colour - Intensity, Luminosity, Reflection. The secret to maintaining colour intensity is the new Colour-Seal Elixir™ which has been developed to intensively condition, to help protect colour from fading and preserve its intensity. Protects Hair. Hair looks vibrant. Prolongs Radiance: The formula with concentrated nourishment intensely nourishes the hair and smoothes its surface. Shine is revived and radiance is prolonged.
