Which of the following actions should be performed as part of pre-service preparation?

The action of turning off your cell phone, washing your hands, taking a few breaths, and centering yourself is essential for effective pre-service preparation. This practice ensures that you create a focused and hygienic environment before performing any hair service. Turning off your cell phone minimizes distractions, allowing you to fully concentrate on the client. Washing your hands is crucial for maintaining cleanliness and preventing the spread of bacteria, while taking a moment to breathe and center yourself helps you enter the service with a calm and professional mindset, enhancing the overall experience for both you and the client.

Other actions, while important in their own contexts, do not specifically pertain to the immediate pre-service preparation. Reviewing past client records can be useful, but it is typically done in advance rather than as part of the immediate preparation just before the service begins. Consulting with a fellow stylist may support teamwork and provide insights, but it is not a necessary step during your own preparation procedure. Similarly, arranging products aesthetically is a good practice for keeping your workspace organized, but it doesn't directly impact your personal readiness to perform the service.
