An at-home hair toner is a product used to modify the color of hair after it has been bleached or dyed. Toners can be used to correct unwanted tones, enhance existing color, or create new shades. For example, a blue toner can be used to neutralize orange tones in blonde hair.
At-home hair toners are a popular choice for those who want to maintain their hair color between salon visits or who want to experiment with different shades without committing to a permanent change. They are also a more affordable option than professional toning services.
