What should a barber do before starting a new service?

Before starting any new service, it is essential for a barber to consult with the client about their preferences and hairstyle goals. This step establishes clear communication, ensuring that the client’s expectations align with what the barber can deliver. This consultation not only helps in understanding the client's desired outcome but also builds trust and rapport, which are crucial in the barber-client relationship.

By discussing preferences, a barber can gather important information regarding the client’s lifestyle, hair type, and any specific requests they may have. This understanding allows the barber to tailor the service accordingly, potentially suggesting styles or products that would work best for the client, ultimately leading to a satisfactory experience.

Other options, while they might seem relevant, do not address the immediate need for clear communication and understanding between the barber and the client. Knowing the client's favorite hair product, discussing tipping etiquette, or testing equipment, while important in their own right, do not directly contribute to crafting a service that meets the client's goals and desires.
