Which of the following practices is crucial for ensuring safety while shaving?

Using minimal pressure with the razor is crucial for ensuring safety while shaving because it helps prevent nicks, cuts, and irritation to the skin. Applying excessive pressure can lead to accidents, especially in sensitive areas, and can compromise the quality of the shave. A gentle approach allows for better control of the blade, reducing the risk of injury and maintaining a smooth shaving experience. This practice is especially important for barbers, as they need to prioritize the safety and comfort of their clients during the service.

Other practices related to shaving, like adjusting techniques based on individual skin types and using appropriate blades, contribute to the overall effectiveness of a shave but may not directly address safety in the same way as using minimal pressure does.
