Which technique is least likely to be used when cutting hair for volume?

When considering techniques for cutting hair to create volume, blunt cutting stands out as the least effective. Blunt cutting involves cutting the hair straight across, which creates a solid, even edge. This technique can add weight and density to the ends of the hair, but it generally does not enhance volume at the roots or throughout the hair structure.

In contrast, layering, thinning, and point cutting are techniques designed to remove weight and add movement, which can significantly contribute to a voluminous appearance. Layering creates varying lengths in the hair, allowing for uplift and body. Thinning reduces bulk and can help define the shape of a haircut without the heaviness that blunt cutting might impose. Point cutting, which involves snipping into the ends of hair at an angle, softens the edge and can enhance texture and movement, both of which also work to promote volume.

Since the goal of the question is to identify the technique least likely to create volume, blunt cutting is the most suitable choice, as it does not align with the objectives of enhancing lift or fullness in a hairstyle.
