A toner is primarily used in hair coloring to neutralize unwanted tones that can arise after the bleaching process or as hair color fades over time. When hair is lightened, it can often develop undesirable hues, such as brassiness or overly warm tones. Toners help to balance and correct these tones, providing a more desirable color that aligns with the client's expectations.

While the other options mention benefits that various hair products may provide, they do not accurately reflect the primary function of a toner. Enhancing hair volume relates to products that provide lift or fullness rather than color correction. Providing shine is typically achieved through finishing products or serums, while moisturizing dry strands is usually addressed through conditioners or deep conditioning treatments. Therefore, the role of a toner is specifically focused on color correction, making it essential for achieving desired hair color results.
