This unit applies to hairdressers in salon environments, who consult with clients, then select from and apply a range of tint, high lift tint and bleach products and techniques to achieve highlighting effects to enhance hair designs.
This application reflects a design context that is influenced by hair colour fashion trends at a given time and involves using single products or combinations of products to create highlights, lightened sections of the head or multiple colours in the hair.
A person undertaking this role applies discretion and judgement and accepts responsibility for outcomes of own work.

Element | Performance Criteria |
Elements describe the essential outcomes of a unit of competency. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
1. Consult with client and prepare for service. | 1.1 Analyse client characteristics through physical and visual examination. 1.2. Discuss client satisfaction or dissatisfaction with current hair colour. 1.3. Establish client expectations through questioning and reference to existing client history. 1.4.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the following is essential: pre-service client consultation that includes accurate hair analysis and establishes client expectations regarding the colour result recognising and managing contraindications to colour and bleach services interpreting and applying colour charts, product instructions and safety data sheets applying weaving and splicing techniques within salon timeframes applying highlighting techniques within salon timeframes observing client and operator safety precautions achieving target highlighting results that satisfy clients providing colour care advice and promoting home care products from the salon range. |
Context of and specific resources for assessment | Assessment must ensure access to: a salon or a simulated salon environment that includes a range of work situations such as client interruptions and involvement in other related activities normally expected in the salon a fully equipped workstation which includes as minimum: an adjustable client chair clean client gown or wrap a plentiful supply of clean towels trolley stocked with: rubber gloves stain prevention products plastic bowls tint brushes applicator bottles foils cap or plastic film wrap documented salon procedures relating to: client comfort and safety operator safety health and hygiene waste minimisation waste disposal water efficiency a professional range of tint and bleach products product colour charts, information and safety data sheets a range of clients with different foiling and highlighting application requirements. For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: observation of the learner performing a range of tasks in an actual or simulated work environment, over sufficient time to demonstrate their handling of a range of contingencies. Tasks include: consulting clients to advise on and confirm colour selection safely applying weaving and splicing single and multi-coloured foil effects within designated salon timeframes, with no product bleed and to client satisfaction safely applying quick service highlighting techniques with no product bleed and to client satisfaction following salon procedures to ensure the comfort and safety of clients completing foiling and highlighting applications within designated salon timeframes advising on colour care and recommending home care products. written or verbal questions appropriate to the language and literacy level of the learner to test knowledge, such as: the effects of hydrogen peroxide on the hair and hair colour the chemical and physical effects of tint and high lift tint colour products on hair structure the chemical and physical effects of bleach products on hair structure the colour wheel and its application in colour selection the levels of bleaching tint and high lift tint colour chart systems for products in the salon range processing and development times for a defined salon tint, high lift tint and bleach product range salon procedures relating to: client comfort and safety operator safety health and hygiene waste minimisation waste disposal water efficiency. review of portfolios of evidence and third-party reports of on-the-job performance. |
Guidance information for assessment | A unit of competency describes an individual skill but people rarely perform one skill at a time. Many skills are combined on a day-to-day basis in the workplace as part of work processes. This does not mean that each skill described by a unit of competency is pre-requisite to another—they are related skills. Holistic assessment with other units relevant to the industry sector, salon and job role is recommended, for example: SIHHCCS302A Perform a full client consultation SIHHCLS304A Neutralise unwanted colours and tones SIHHOHS201A Apply salon safety procedures |
