What issue can overlapping color cause?

Overlapping color can create a noticeable line of demarcation, which refers to a distinct separation between two different colors or color treatments on the hair. This occurs when new hair color is applied over previously colored hair, particularly if the overlap causes the previously colored sections to receive additional pigment. This often leads to darker sections where the overlapping color has deposited more product, resulting in an unnatural appearance that can be visually jarring.

Managing color application is crucial for achieving a seamless blend and maintaining a consistent look. Understanding how to avoid overlapping color is key for hair colorists to create beautiful, harmonious results without harsh lines between different shades. In contrast, while fading, staining, and frizzing can also be concerns in hair color application, they are typically not directly related to the application technique involving overlapping color.
