What is the primary use of a toner in hairstyling?

The primary use of a toner in hairstyling is to correct or enhance hair color. Toners are typically applied after a bleaching or highlighting process to adjust the tone of the hair. This is essential because lightening hair can often result in unwanted brassy or yellow tones. Toners work by neutralizing these undesired shades and can either cool down the color with ash or violet undertones or warm it up with golden or creamy tones, depending on the desired outcome.

They can also enhance the overall vibrancy of the color, ensuring that the final result aligns with the client's expectations. This makes toners a crucial tool in achieving a polished and professionally finished look in color-treated hair.
