The L'Oréal laboratories have created a formula which acts on 3 Dimensions of colour - Intensity, Luminosity, Reflection. 1. Maintains Colour Intensity: The new Colour-Seal Elixir™ has been developed to intensively condition, to help protect colour from fading and preserve its intensity. 2. Protects Hair: The formula enriched with UVA/UVB Filters protects coloured hair from external aggressions. Hair looks full of life. 3. Prolongs Radiance: The formula with concentrated nourishment intensely nourishes the hair and smooths its surface. Shine is revived and radiance is prolonged.
