What tool is used for more precise cutting in hair styling?

Shears are the primary tool used for more precise cutting in hair styling. They are designed with straight blades that allow for clean and controlled cutting. This makes them suitable for creating defined lines, angles, and symmetrical shapes in hair. Shears enable stylists to achieve a variety of cutting techniques, such as blunt cuts or layering, with a high level of accuracy.

While razors can also create a textured look and add softness to the ends of the hair, they do not provide the same level of precision for defined cuts. Thinning shears, on the other hand, are specifically designed to remove bulk and add texture, rather than to create sharp lines or detailed styles. Clippers are mainly used for bulk cutting and creating fades or shorter styles, not for detailed work. Therefore, among the listed tools, shears are the choice that allows for the most precision in hair cutting.
