This unit requires the operator to communicate with clients regarding their colour problem and desired hair colour finish. It involves analysis of the characteristics of hair, including hair condition, existing chemical damage, natural base colour, artificial base colour/s and the selection and application of products that remove and correct unwanted colour, colour undertones or bleached effects from the hair.
Knowledge of the workplace hair colour/lightening range and colour correction products, along with a knowledge of relevant local health regulations and the workplace approach to colour services, with particular emphasis on client and operator safety, are also required.
In the context of an assessment-only and/or a training delivery and assessment pathway, units of competency that relate to this unit are identified in the evidence guide of this unit.

The evidence guide describes the underpinning knowledge and skills that must be demonstrated to prove competence. It is essential for assessment and must be read in conjunction with the performance criteria, the range statement and the assessment guidelines of the relevant Training Package.
Overview of assessment
A person who demonstrates competency in this unit of competency must be able to apply knowledge of the use and application of a broad range of products to solve complex colour problems on different clients. This will take the form of working in a team to provide technical advice to other operators on colour correction strategies and techniques. Knowledge of and skill in applying relevant legislation and workplace procedures that ensure client and operator comfort, health and safety must also be demonstrated.
Specific evidence requirements
Critical aspects for assessment and evidence required to demonstrate competency in this unit
knowledge and consistent application of workplace policies, procedures and safe work practices in relation to colour services
consistently applying effective questioning and active listening techniques to consult and negotiate with clients and to ensure client comfort and safety throughout the service
recognising and managing contraindications
reading, accurately interpreting and consistently applying manufacturer's colour charts and product instructions
consistently safe selection, preparation, application, processing and removal of colour according to manufacturer's instructions and workplace procedures
consistently developing specialist product knowledge and techniques
consistently providing sound information and advice to clients and relevant workplace personnel, based on the consideration of time, and cost and risk factors associated with possible corrective services
consistently applying specialist colour corrective services.
Context of assessment
For valid and reliable assessment of this unit, competency should be consistently demonstrated over a period of time and observed by the assessor and/or the technical expert working in partnership with the assessor. The technical expert may include the hairdresser and/or an experienced person at the workplace.
Competency should be demonstrated in the workplace or a simulated workplace environment in a range of situations that may include client interruptions and involvement in other related activities normally expected in the workplace. For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package.
Specific resources for assessment
Competency for this unit should be assessed through access to:
relevant documentation, including occupational health and safety legislation and regulations, workplace policy and procedures manuals and manufacturer's product safety data sheets
a salon or simulated salon environment
products and information from key product manufacturer's colour ranges
clients with a variety of complex hair colour problems.
Relationship to other units
This unit requires an assessment outcome that includes evidence of advanced technical knowledge of the chemical and physical effects of hair colour and lightening colour products on the hair. In a workplace environment, solving complex colour problems requires significant experience in colour and lightening services and the application of colour correction practices.
WRHCL302B Colour and lighten hair
WRHCL303B Design and perform full and partial highlighting techniques
WRHCL304A Perform colour correction.
WRHCL305B Perform on scalp full head and re-touch bleach services.
Method of assessment
The following assessment methods are suggested.
