What is the best way to achieve a more voluminous haircut?

Achieving a more voluminous haircut is effectively accomplished by using layers throughout the hair. Layering reduces the weight of the hair, allowing it to move more freely and create an illusion of volume. When hair is cut in layers, it also enhances texture and adds dimension, making it appear fuller.

In contrast, cutting hair all to one length can create a solid, heavy look that often lacks movement and volume. Similarly, using heavy products to weigh down the hair would counteract the goal of increasing volume, as they can make hair feel flat and lifeless. Avoiding any type of layering would also inhibit the natural movement and lift that contributes to a voluminous appearance. Therefore, layering is the most effective technique for adding volume to a haircut.
