For what purpose is a "bleach wash" used?

A bleach wash is utilized primarily to lighten hair without performing a full bleach application, making it a lighter and less harsh alternative for those seeking a subtle change. This technique mixes a bleach agent with shampoo, which allows for a more gentle lifting of color. It offers a way to refresh faded colors or lighten the base slightly while maintaining some of the natural depth and tones in the hair.

In contrast to the other options, using a bleach wash is not specifically about completely removing colors or preparing for dyeing; those might require more intensive techniques or products. Additionally, it doesn't serve the purpose of conditioning damaged hair, as its primary focus is color modification rather than hair health or repair. Therefore, understanding the specific benefits and applications of a bleach wash is essential for effective hair coloring practices in a salon setting.
