What is the name of the technique used to create volume in the hair?

Layering is a fundamental haircutting technique used to create volume in the hair. This method involves cutting the hair at various lengths, which can enhance movement and body, giving the appearance of fuller hair. When hair is layered, shorter strands are able to "float" above longer strands, creating a more volumized look. This technique is especially beneficial for individuals with fine or flat hair types, as it helps to lift the hair away from the scalp and add structure to the overall style.

In contrast, balayage refers to a hair coloring technique that involves hand-painting highlights onto the hair, which does not specifically address volume creation. Texturizing, though it can add some movement to the hair, primarily focuses on removing bulk and creating definition rather than directly increasing volume. Undercoating is a less commonly used term and typically refers to a specific cutting method that may not be as widely recognized for volume enhancement in comparison to layering. Thus, layering stands out as the most effective technique for achieving volume in the hair.
