L'Oreal Dia Richesse Ammonia-Free Dye 5.42 50ml is a tone-on-tone hair colour that helps to achieve the desired shades and highlights in hair. Its ammonia-free formula reduces the impact of the dye on the hair and helps to create deep, lustrous shades. It is a semi-permanent colouring, with approximate durability of up to 6 weeks.
*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.
