What is the purpose of using a toner after coloring?

Using a toner after coloring serves the specific purpose of adjusting or enhancing the final color tone of the hair. Toners are particularly useful for neutralizing unwanted undertones, such as brassy or yellow shades, that can appear after the initial hair coloring process, especially when lightening hair. By applying a toner, a stylist can refine the hue to achieve a more desirable shade, whether that involves making a color more vibrant, cooler, warmer, or simply more balanced.

This process is crucial for achieving professional-looking results, as it allows for precision in color correction and can enhance the overall aesthetic of the hair. Toners can also impart a shine to the hair, adding to its overall health and appearance, but the primary function in this context is focused on color enhancement.

The other options do not accurately reflect the primary intent of toner application. Removing all color, softening the hair, or preventing it from drying are specific functions associated with other products or treatments, rather than the primary purpose of toner. Thus, the answer highlights the essential role of toner in achieving the desired hair color outcomes post-coloring.
