Which of the following is a common tool used for texturizing hair?

The use of a razor is a common technique for texturizing hair because it allows for a soft, feathered look and creates different layers and textures within the hair. Unlike shears, which provide a blunt cut, razors can remove weight and add movement, making them ideal for achieving a more blended and natural appearance. This technique is particularly effective for certain hair types and styles where a lighter, airier feel is desired.

While shears can be used for cutting and layering, they typically do not provide the same texturizing results as a razor. Clippers are more suited for achieving short haircuts or uniform lengths rather than adding texture. A comb is used primarily for sectioning and styling hair but does not alter the hair's texture directly. Therefore, utilizing a razor is recognized as a primary method for texturizing hair in various hairdressing techniques.
