What cutting technique involves partially opening and closing the shears while moving through the hair?

The cutting technique that involves partially opening and closing the shears while moving through the hair is known as carving. This method allows for precision and texture as the stylist sculpts the hair rather than just cutting it straight across. Carving is particularly useful for creating soft, blended layers and adding movement to the hair without removing too much length. It requires a delicate touch and good control of the shears, which enhances the overall style by introducing subtle variations in length and weight throughout the hair.

Slicing, on the other hand, typically involves cutting with a steady motion through the hair to remove bulk and create softness, while beveling focuses on cutting the hair at an angle to create a rounded edge. Layering is a broader technique used to create gradual changes in hair length, which adds volume and shape. Each of these techniques has its own specific application, but carving stands out because of its unique approach that combines cutting and texturing in a fluid, dynamic manner.
