What is the first step of double-process haircoloring?

In double-process haircoloring, the first step is pre-lightening. This process is essential because it involves lightening the natural pigment of the hair before applying the desired hair color. Pre-lightening allows for a more vibrant and true-to-tone final color, especially when working with shades that are significantly lighter than the client's natural hair color or when removing unwanted tones.

This step is crucial for achieving the desired base level, which enables the subsequent color application to develop properly and appear more saturated and vivid. Skipping this initial step can lead to dull or unexpected results, making pre-lightening a foundational aspect of the double-process technique.
