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 aggression. Hair looks full of life. 3 Prolongs Radiance: The formula with Concentrated Nourishment intensely nourishes the hair and smoothens its surface. Shine is revived and radiance is prolonged.
