What tool is commonly used to uniformly thin the hair without removing weight?

Notched thinning shears are designed specifically for uniformly thinning hair while maintaining some of its weight and bulk. These shears typically have a series of notches or teeth that allow hair to be removed selectively, giving a softer, more blended appearance to the haircut. This technique is particularly useful for layering and reducing volume without altering the overall length drastically.

Regular scissors do not have the same specialized design as thinning shears and are primarily used for cutting hair straight across. Razor blades can also create texture and remove weight but can lead to split ends if not used correctly and are not specifically designed for thinning hair uniformly. Clippers are primarily used for cutting hair to various lengths and creating clean lines, making them less suitable for the finer thinning work or blending that notched thinning shears achieve.
