What is the process called where the hair is lightened before color is applied?

1. Single-process hair coloring

2. Double-processing hair coloring

3. Bleaching

4. Toning

The correct answer is: Double-processing hair coloring

Single-process hair coloring is the application of a single color to the hair, without any lightening or bleaching beforehand. Bleaching, while a part of the double-processing hair coloring process, is not the full process. Toning happens after the hair has been lightened and is used to achieve a specific shade or tone. The process in question, where the hair is lightened before color is applied, is specifically known as double-processing. This is because it involves two steps bleaching or lightening the hair first, and then applying the desired color. This is different from single-process hair coloring, which does not involve any lightening step. It is also different from just bleaching or toning, as those are often done separately and not as part of a single process. Therefore, the correct answer is B: double-processing hair coloring.
