In this industry, Hairdressers cut, style, color, straighten and permanently wave hair and provide clients with hair and scalp treatments. In most salons, the senior hairdressers and the more advanced apprentices cut and style hair. Apprentice hairdressers undertake routine tasks in the initial stages of employment, assisting senior hairdressers with preparing clients, shampooing, applying and removing simple hairdressing treatments, and sterilizing and maintaining equipment. As apprentices gain experience they carry out more complex tasks under supervision.
