Matrix Color Insider Ammonia Free Hair Colour 7G 67ml is a permanent hair dye that does not incorporate ammonia, which helps to achieve the desired colour without damaging the cuticle. It can lighten the hair up to 3 shades and its formulation helps to protect the hair structure during colouring for a uniform and intense finish.
*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.
