What is the main purpose of using a toner in hairstyling?

Using a toner in hairstyling primarily serves the purpose of adjusting hair color and removing unwanted tones. When hair undergoes a coloring process, particularly when lightening, it can often take on various unwanted undertones, such as brassiness or yellow hues. A toner helps neutralize these tones, making the overall color appear more balanced and aesthetically pleasing.

For example, a purple toner is often applied to yellowish blonde hair to cancel out the warm tones, resulting in a cooler and more desirable shade of blonde. Furthermore, toners can enhance and refine the hair's overall color, providing more depth and richness, which is particularly important in achieving a professional-looking finish.

While other options mention changing hair texture, adding volume, or strengthening hair follicles, these do not accurately describe the key function of a toner, which is focused specifically on color adjustments and tonal correction.
