Colour Enhance Oil has been specially formulated to nourish, and indulge coloured hair. It is enriched with a blend of Avocado and Argan Oils to revitalise and moisturise hair, whilst enhancing the colour. A common myth is that oils will make hair look and feel greasy, but as long as you don't overload your hair, and add a little oil at a time, they really are the perfect product for hydrating dry or damaged hair.
