What type of hair cutting technique involves using a razor?

Texturizing involves using a razor to create a softer, more blended look in the hair. This technique can vary the length and remove bulk without altering the overall length significantly, helping to create movement and texture. By cutting hair with a razor, stylists can achieve a feathery or wispy effect, enhancing the natural flow of the hair. It's especially effective on hair that is already layered or on fine hair, giving it added volume and texture.

In contrast, the other techniques mentioned do not primarily use a razor. Clipper cutting utilizes clippers for precise cutting, point cutting involves snipping the ends of hair to create texture and remove weight but typically uses shears, and slicing uses a subtle cutting motion with scissors that doesn't necessarily involve the razor.
