Dia light is formulated without ammonia and used to gloss, tone, and refresh color. We recommend Dia light be used after all lightening services. • Tone, gloss, refresh previously colored or sensitized hair. • Gentle acid technology smooths the cuticle for vinyl shine. • Provides intense care for the hair. • Provides zero lift. • Not for white coverage - for white coverage of up to 70% white, we recommend Dia color.
