Which technique would typically be used to add depth to the hair color?

Lowlighting is a technique specifically designed to create depth in hair color. It involves applying darker shades to strands of hair to add dimension, contrast, and richness. By incorporating darker colors, lowlighting can give the illusion of fuller, more voluminous hair while also enhancing the overall appearance of the hairstyle. This is particularly effective for individuals with lighter hair who want to introduce darker tones without making a dramatic change.

Highlighting, on the other hand, focuses on lightening certain areas to add brightness and dimension but does not typically contribute to a deeper color experience. Balayage is a freehand technique that creates a sun-kissed effect with lighter highlights, and bleaching is primarily used to remove color altogether rather than adding depth. Therefore, lowlighting is the most suitable technique for those aiming to create a deeper, more dimensional look in their hair color.
