What type of color application involves sectioning the hair and applying color using a brush and bowl?

The process referred to in the question involves sectioning the hair and applying color using a brush and bowl, which is characteristic of an all-over color technique. This method is typically used when a stylist wants to apply a uniform shade of color to the entire head of hair.

In all-over color applications, the hair is generally divided into sections to ensure even and thorough coverage. The stylist uses a bowl to hold the color mixture and a brush for precision in application. This technique is beneficial for clients seeking a complete color change, whether that’s to cover gray hair or to achieve a new hue.

Other techniques like foil coloring, balayage, and highlighting have specific methodologies and may use additional tools or processes. For example, foil coloring involves wrapping sections of hair in foil to isolate the color application, which is different from the direct application method of all-over color. Balayage is a freehand highlighting technique that creates a more natural and sun-kissed look. Highlighting typically focuses on adding lighter tones to specific strands or sections rather than changing the entire color. Thus, the defining characteristic of all-over color is the complete and uniform application across the entire head.
