What does the "zone" concept refer to in coloring hair?

The "zone" concept in coloring hair refers to targeting specific areas for color application based on hair length. This approach recognizes that different sections of hair may need distinct techniques and color formulations due to variations in length, texture, and existing color.

By using the zone concept, hairstylists can ensure that the color is applied more effectively, enhancing the overall look and ensuring that the color is distributed in a way that complements the individual’s features and style. This method is particularly important for techniques like balayage or highlights, where certain areas require more attention to achieve the desired effect. The method acknowledges that hair does not receive color uniformly, and adjusting application based on specific zones leads to a more personalized and aesthetically pleasing result.

Each part of the head—such as the crown, mid-lengths, and ends—can be treated differently, allowing for tailored results that contribute to the overall design and dimensionality of the hairstyle.
