Schwarzkopf IGORA Royal Oil Developer is a specially developed high-performing peroxide developed by colorists for colorists. Oil developer is to be used with oil base color and not a cream based as it is a chemical reaction occurring- the BSO advises and recommends strongly manufacturers directions. Its innovative Lipid Carrier System and increased oil content enable color pigments to penetrate faster into the hair, giving more intense, longer-lasting color results. It provides a sealing effect on the hair, giving more shine and luster, perfect equalization of color from the roots to the tips, and improved overall performance.
