The intensive shades of Tinta Color Red Infinity are created with the new color pigment Red Infinity (RI) and gives intensive characters and exceptional durability. These intense red shades offer unsurpassed intensity with proven longer lasting color and intensive coverage. The color pigments have an oxidative structure -meaning that once they enter the hair the small pigments join together to form a larger color structure. The Red Infinity pigments form larger structures than comparable Red shades, which ensure that, within both permanent and semi-permanent ranges, the color is more fade resistant and thus extremely durable.
