Boosters contain a high pigment intensity, ideal for accentuating and intensifying the saturation of a color. Mix with other shades in proportional quantities depending on the end desired result. Mix 1 to 15 grams of Booster to every 50 grams of color. (Do not consider in the mixture with hydrogen peroxide).
Use in a mixture with other shades to reduce the intensity of the color. Use Neutral alone to increase the brightness / reflection of the hair. USAGE: add ¼ to ½ of a tube in the color formula to reduce the intensity of the tone.
