Which tool is primarily used for removing bulk from the hair?

Thinning shears are specifically designed to remove bulk from hair while blending layers together. They have a unique design that features one straight blade and one serrated blade, which allows them to cut less hair and create texture without changing the overall length significantly. This tool is particularly useful for clients who have thick, voluminous hair and want a lighter feel or more movement without drastically shortening their hair.

In contrast, clippers are primarily used for cutting hair very short and creating defined lines, while a razor is excellent for adding texture and softening ends without removing much bulk. Scissors are versatile but are typically used for cutting straight lines and precise lengths rather than specifically for thinning out hair. Each of these tools has a distinct purpose, but for the specific task of bulk removal, thinning shears are the most effective choice.
