WHAT IS IT? A line of four developers (10, 20, 30 and 40 volume) and a balancing lotion, designed to be used with all RUSK® haircolor and lightening products for reliable, consistent results. When used with Deepshine® Pure Pigments Conditioning Cream Color, they provide uniform, long-lasting color and maximum gray coverage.
WHO IS IT FOR? Anyone looking for optimal and predictable color results, and superior gray coverage.
WHAT DOES IT DO? When mixed with Deepshine® Pure Pigments Conditioning Cream Color, Deepshine® Shine Enhancing Cream Developers and Balancing Lotion produce the proper pH to ensure maximum tone, depth and color durability without compromising the integrity of the hair fiber. Active conditioning agents ensure that the hair looks and feels healthy, soft and shiny.
HOW DO YOU USE IT? Choose the appropriate developer depending on your need. Use 10 volume for optimum gray coverage or to lift a natural shade up one level, 20 volume to lift natural level up to two levels, 30 volume to lift natural level up to three levels, 40 volume to lift natural level up to four levels. Use the balancing lotion to refresh color balance tone from roots to ends, and for demi-permanent results. Mixing ratio for a standard Deepshine® color formulation is 1 part color to 1½ parts developer or balancing lotion (1:1 1\/2).
