I use Aveda for my permanent and Demi-permanent color line because it is completely customizable. I do not squeeze out a red brown color from a tube. I squeeze out the base color (levels 1-10) and then add as much red as desired. I use Robson Peluquero as a pre-tone because it doesn’t require a developer which could lift natural hair. I use Pulp Riot for my vivid because I can apply it on wet or dry hair and the color doesn’t bleed.
