This unit describes the performance outcomes, skills and knowledge required to consult with clients and analyse hair and facial characteristics to design, recommend and complete a range of complementary hairstyles using hair extensions. It involves selecting and applying full or partial hair extensions to increase the length and volume of hair or to introduce additional colours. Extensions may be human, animal or synthetic hair.

This unit applies to hairdressers with well-developed skills who work in hairdressing salons or as session stylists. They use discretion and judgement to manage the client service and take responsibility for the outcomes of their own work.

No occupational licensing, certification or specific legislative requirements apply to this unit at the time of publication.
