L'Oreal Blond Studio 7 Level Lightening Clay Powder 500g is a bleaching powder that helps to lighten hair by up to 7 shades. Its formulation is ammonia-free and helps to obtain natural blonde hair tones. Its 19% clay composition creates a flexible film around the hair that protects the cuticle during bleaching.
*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.
