Salerm Hydrogen Peroxide 40Vol 12% 225ml is the oxidising agent that will help reveal the colour of the dye. It includes conditioning components that help to protect and soften the hair during the colouring process, helping to enhance the hair's shine.
*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.
