The main job of a barber is to cut a client's hair. The goal is to improve the appearance of the hair and to adapt styles to the customer's wishes. Barbers also shape and trim beards and mustaches. Instruments such as scissors and combs must be kept sterile and in good condition, and the barber is also responsible for keeping the shop clean by sweeping up hair. Owners of barbershops also order supplies, pay bills and may hire and supervise staff. Good interpersonal skills and a positive attitude are important qualities to have when working as a barber. Examples of famous barbers are Alex Kelly and Cameron Kelly formally known as the Kelly Cutters. Many barbers use these men as examples and aim to also deliver a very high quality service.
