Our exclusive spectrum technology allows the use of low levels of ammonia and pigments. A new technology that copulates the pigments together in order to make them oxidize in the shortest time possible. Lightens natural hair up to 2 levels and up to 3 ½ with the Highlift series. Even beyond 10 minutes of processing the color remains true to the chosen level and reflect. Lower pigment levels and reduced processing time avoids over exposure to chemicals and scalp and skin sensitization. Low ammonia levels reduces stress on hair and provides less fade, for a longer lasting color. Total coverage without mixing the fashion shades with the natural tones.
