What is the process of doing a highlight in reverse by adding darker color to previously lightened hair?

The process of adding darker color to previously lightened hair is known as reverse highlighting. This technique is specifically designed to create depth and dimension in the hair by introducing darker shades. It effectively contrasts the lighter strands, which can enhance the overall look by adding richness and preventing the hair from appearing too flat or one-dimensional.

Reverse highlighting is particularly useful for clients who may feel that their hair has become too light or wants to transition to a darker style without completely losing their lighter strands. The darker color can help to blend and soften the overall appearance, contributing to a more balanced hairstyle.

Highlighting, on the other hand, involves adding lighter colors to the hair and doesn't address the process of darkening previously lightened hair. Shading typically refers to adding depth through various techniques but isn’t specifically about reversing highlights. Streaking might imply adding highlights or lowlights but does not capture the essence of intentionally darkening previously highlighted areas. Thus, reverse highlighting is the most accurate term for this specific coloring technique.
