Don't trust the model on the box. Sure, the woman smiling on the front of the box looks beautiful, but the color of her hair is a fantasy. "The color always ends up lighter than the model's hair on the packaging," says colorist Dana Ionato of the Sally Hershberger Downtown salon in New York City. "The developer in at_home permanent dyes is very strong stronger that the ones we use in the salon so it lifts the color and makes it lighter than what you see on the box." A better estimate on how the color will end up is the chart on the top of the box, which shows you the final color you get from a range of different hair_color shades.
Keep in mind that even a brand so committed to natural formulas must rely on some synthetic ingredients in order for the hair color used in its salons to work. "The remaining 4% of the ingredients are of synthetic content which are the colorants, dyes and preservatives," Mejia_Montane explains. "It is unavoidable to include synthetic ingredients in professional hair color because all of the colorants and dyes used in permanent and demi_permanent hair color are synthetic. These are the ingredients that create hair color via the oxidation process."
