What color technique can add dimension to a hairstyle?

Balayage and highlighting are both color techniques that can effectively add dimension to a hairstyle.

Balayage is a freehand technique where the color is painted onto the hair, creating a natural and sun-kissed look. This method allows for a seamless transition of color, enhancing the hair's depth and creating an organic feel. The placement of color can be customized to suit the individual's hair type and face shape, adding rich, multi-dimensional tones that catch the light beautifully.

Highlighting, on the other hand, involves lightening specific strands of hair to create contrast with the base color. This technique can vary in intensity and placement, allowing stylists to create everything from subtle brightness to bold statements. Highlights can frame the face, add texture, and contribute to the overall dimensionality of a hairstyle.

Both balayage and highlighting serve to break up the monotony of a solid color, enhancing the hairstyle's visual interest and depth. Therefore, the answer indicates that both techniques are effective in achieving dimensional color, making it the best choice for this question.
