Which haircut creates the most bulk in the hair?

The haircut that creates the most bulk in the hair is the zero-degree cut. This technique is often referred to as a blunt cut, where the hair is cut straight across without any layering or graduation. By cutting the hair to the same length all around, it retains maximum weight and volume, resulting in a fuller appearance.

In contrast, other cutting techniques, such as the 45-degree, 90-degree, and 180-degree cuts, involve varying degrees of layering or graduation, which tends to remove bulk and create more movement in the hair. While these methods can produce beautiful styles with texture and dimension, they do not provide the same level of fullness that a zero-degree cut offers.

Understanding the impact of different cutting techniques on hair volume is essential for achieving desired styles and managing a client's overall look. Therefore, the zero-degree haircut is the most effective for creating bulk and density in the hair.
