Applying toner in hair coloring primarily serves to adjust the tone of previously colored hair. Toners are used after the initial coloring process to neutralize unwanted undertones that may arise from the hair dye. For example, if a blonde hair color develops brassy yellow or orange tones, a toner can be applied to create a cooler or more neutral shade, such as ash or beige. Toners work by altering the color of the hair at a more subtle level, allowing for fine adjustments that can enhance the overall appearance and achieve the desired hair color. This step is crucial for achieving results that are visually appealing and can maintain the vibrancy of the color for a longer period. While other options mention benefits like lightening hair, providing extra shine, or protecting against damage, these do not directly pertain to the primary function of toner in hair coloring. Lightening is achieved through different bleaching processes, shine usually results from conditioning treatments or hair products, and damage protection typically involves the use of specific hair care products rather than toner itself. Thus, the main advantage of toner lies in its ability to fine-tune the shades and tones of the hair after it has been colored.
