What is the main consideration when using a razor for cutting hair?

The main consideration when using a razor for cutting hair is the angle of the blade against the hair for precision. This is crucial because the angle at which the razor is held can significantly affect the outcome of the cut. A proper angle allows for clean, smooth lines and can influence the texture and movement of the hair. For instance, holding the razor at the correct angle minimizes the risk of damaging the hair cuticle and can contribute to a softer, more blended appearance.

In contrast, while the type of hair product applied before cutting, the length of hair before the cut begins, and the client's preferred hair length are all important aspects of the overall haircutting process, they do not have as direct an impact on the technique of using the razor itself. The precision achieved through the correct angle is what ultimately determines the effectiveness and quality of the haircut.
