During shaving, what action does the left hand typically perform while the right hand holds the razor?

During shaving, the predominant role of the left hand is to gently stretch the skin. This action is crucial for achieving a clean shave and minimizing the risk of nicks and cuts. By pulling the skin taut, the left hand creates a smoother surface for the razor, allowing for closer contact with the hair. Stretching the skin also helps to lift the hair slightly, making it easier for the razor to cut effectively.

In this context, holding the client's head still or applying shaving cream does not fall within the typical responsibilities of the left hand during the shaving process, as these actions may disrupt the stability or the intended technique of the shave. Guidance of the razor edge is primarily the responsibility of the right hand, which is where the barber has better control and precision. Therefore, gently stretching the skin remains the key responsibility of the left hand in ensuring a precise and safe shaving experience.
