Which haircut technique results in a stacked appearance?

The haircut technique that results in a stacked appearance is the graduated cut. This technique involves cutting the hair at an angle, creating layers that are shorter at the back and gradually become longer towards the front. This creates a visual effect that resembles a stack, as each layer builds upon the one below it, forming a three-dimensional look. The graduated cut provides volume and movement, making it a popular choice for styles that aim to have body and fullness.

In contrast, layering focuses on cutting the hair at varying lengths throughout, which can create texture but does not necessarily offer the same stacked look. A blunt cut results in hair being cut straight across, lacking the angle and dimension that define graduated cutting. While a 45-degree angle cut may add some layering, it typically does not achieve the distinct stacked effect associated with a graduated cut.
