What tool is primarily used for texturizing hair?

Thinning shears are specifically designed to reduce the bulk of hair and add texture while maintaining length. They feature a unique design with one serrated blade and one straight blade, allowing for selective cutting of hair strands. This results in a layered effect that enhances movement and reduces heaviness, making it ideal for texturizing hairstyles.

In contrast, round brushes are typically used for curling and smoothing hair during blow-drying, while combs serve primarily for detangling and sectioning hair. Hair clippers are used mainly for cutting hair to a uniform length, rather than for texturizing. Thus, thinning shears stand out as the optimal choice for achieving texture in hair styling.
