oVertone conditioners are not dyes — they’re pigmented conditioners! Dyes contain chemicals formulated specifically to dry and open the hair cuticle and deposit color, and oVertone conditioners contain none of those chemicals. While you can add color to your hair with them, our conditioners are not formulated to be a one-time application like a dye. They are designed to gradually replace the pigments you lose every time you wash your hair, so your color is perfect every single day, whether you were in a salon four days ago, four months ago, or never!
