What is the general term for permanent hair colors mixed with low-volume developers?

The correct answer is toners. Toners are specifically designed to alter the tone of the hair after it has been lightened or processed with bleach. When mixed with low-volume developers, they can effectively deposit color onto the strands, neutralizing unwanted tones and achieving the desired shade. This process is essential for creating subtle color corrections, enhancing shine, and achieving pastel or blonde shades without significantly altering the hair's underlying structure.

Low-volume developers are often used in this context because they contain a lower concentration of hydrogen peroxide, making them gentler on the hair while still allowing for effective tone application. This is in contrast to high-lift colors, which are formulated to lift the natural color while depositing color simultaneously; vivid colors, which are typically bright and bold shades; and lighteners, which focus on lifting the hair color without the intent of depositing a specific tone. Understanding the role of toners is crucial for achieving beautiful, balanced hair color results.
