Why should barbers avoid excessive pressure when shaving?

Barbers should avoid excessive pressure when shaving primarily to prevent cuts and irritation to the skin. Using too much pressure can lead to nicks and cuts, compromising the client's safety and comfort. The skin is sensitive, especially when wet and subjected to a razor, so maintaining a gentle touch helps protect it from injury. Irritation can also occur when the skin is pressed too hard, leading to redness, bumps, or even razor burn. Therefore, employing a light touch ensures a safer, more pleasant experience for the client while still achieving a clean shave. Other options, while they may seem related to aspects of shaving, do not address the critical importance of skin safety and comfort as effectively as this correct answer does.
