L'Oreal Dia Light Hair Dye No 5.52 50ml is a colour rinse that lasts approximately 6 weeks. Its ammonia-free formula allows for shade customisation by reducing the impact on the hair. In this way, it helps to create brighter shades, undertones and highlights. It allows 30% coverage of grey hair.
*Colouring may cause allergic reactions. Therefore, a skin allergy test should be carried out before application. Apply a small amount of colouring to a sensitive skin area, such as the inside of the elbow. If after 48 hours no reaction is observed, proceed to the global application of the product all over the hair.
