What is the purpose of using a toner in hair coloring?

1. To lighten the hair color

2. To adjust the color tone and eliminate unwanted brassiness

3. To add shine to the hair

4. To strengthen the hair

The correct answer is: To adjust the color tone and eliminate unwanted brassiness

The purpose of using a toner in hair coloring is to adjust the color tone and eliminate unwanted brassiness. Toners are specifically formulated to refine and enhance the desired color by neutralizing brassiness that can occur, particularly in blonde and highlighted hair. This process typically involves the use of blue or purple pigments that counteract warm, yellow, or orange undertones, providing a more balanced and aesthetically pleasing result. While it is true that some products can lighten hair or add shine, these functions are not the primary role of toner. Additionally, toners do not strengthen the hair; instead, they focus on altering the color and imparting a more uniform appearance. Understanding this distinction is critical for effectively addressing color corrections and achieving the desired hair color outcome.
