What is the difference between a toner and a hair dye?

A toner is specifically designed to adjust or correct the underlying tones in hair color, often used after bleaching to eliminate unwanted brassiness or yellow tones. It typically has a more subtle effect compared to permanent or semi-permanent hair dyes. Toners often contain pigments that can neutralize unwanted hues, making them essential for achieving the desired shade, particularly in blonde or gray hair.

On the other hand, hair dye is formulated to add significant color to the hair. It can completely change the hair's original color and provides a more permanent solution. Hair dyes penetrate the hair shaft and deposit color molecules, resulting in long-lasting color changes compared to the more temporary nature of toners.

This distinction highlights the primary functions of toner as a color corrector and hair dye as a means of adding color. Understanding these differences is crucial for effective hair coloring and achieving the desired look while maintaining hair health.
