L'Oreal Blond Studio 9 Oil Activator 30 Vol 9% 1000ml is an oil-based colour developer that works as an oxidising component for the Nutri-Developer Platinium hair colour range. It helps to enhance vibrant blonde hair and its oil texture contributes to an easier and more homogeneous colour application.
*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.
