The main objective of the emulsion is to facilitate the fixation of semi-permanent dyes without ammonia, activating the dye formula to allow the development of pigments and perfect integration with the hair root. Due to its adjusted percentage of peroxide, it is an ideal product for not punishing colored hair excessively, preserving hair integrity. *Coloring can cause allergic reactions. For this reason, a skin allergy test must be carried out before its application. To do this, apply a small amount of dye to an area of sensitive skin, such as the inside of the elbow. If no reaction is seen after 48 hours, proceed to global application of the product throughout the hair.
