Brown hair toner, an acidic dye, alters the tones and hues within brown hair, creating more dimension and vibrancy. For instance, using an ash toner can neutralize unwanted orange or red undertones.
Relevant in the world of hair coloring, toners provide benefits such as enhancing hair's natural depth, correcting color imbalances, and refreshing faded dye jobs. Historically, toners have evolved from traditional ammonia-based formulas to gentler, semi-permanent options.
