Perform chemical straightening and relaxing services

Assessment tool

Version 1.0
Issue Date: April 2024


This unit requires the operator to communicate with clients regarding their expectations of the finished hair design and the degree of relaxing of curl or wave. It requires knowledge of the action of chemical straightening and relaxing chemicals on the hair's structure and contraindications, as well as pre-service hair analysis. Knowledge of the workplace product range, workplace procedures and relevant local health regulations is required, along with attention to client safety and comfort throughout the service.

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.

This unit describes the skills and knowledge required to design and perform chemical straightening and relaxing services to reform curl or wave in the hair.

This unit of competency will apply to a range of chemical reformation services and roles in the workplace.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 consistently perform pre-service hair analysis, consult with clients regarding the desired curl/body result, and then perform the full chemical straightening and relaxing service to achieve that outcome to the satisfaction of the client. Client and operator safety must be ensured at all stages during the chemical straightening and relaxing process.

Knowledge and skill in the application of relevant legislation and workplace policies and procedures must also be demonstrated.

Specific evidence requirements

Critical aspects for assessment and evidence required to demonstrate competency in this unit

consistently conducting accurate pre-service hair and scalp analysis

consistently selecting products, equipment and techniques appropriate to desired outcomes and predetermined designs

consistently applying straightening products and techniques without hair breakage

consistently and successfully assessing the development of degree of curl/wave relaxing

consistently performing the full rinse and neutralising service according to manufacturer's instructions and/or workplace procedures

consistently applying safe work practices and manufacturer's instructions.

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 range of hair straightening products and equipment

a variety of clients presenting with a range of hair types and chemical hair straightening or relaxing requirements

a hairdressing salon or simulated salon area.

Relationship to other units

This unit requires an assessment outcome that includes evidence of well-developed client communication skills, knowledge of the chemical and physical effects of chemical straightening and relaxing products on the hair, and the ability to apply safe working practices during chemical services.

Method of assessment

The following assessment methods are suggested.

Observation of the learner performing a range of tasks in an actual or simulated work environment, over sufficient time to demonstrate his/her handling of a range of contingencies. Tasks may include:

conducting pre-service analysis

predetermining with client the finished degree of straightening and relaxing

selecting products and equipment

completing a number of full services to achieve a predetermined straightening result

recommending after service products and hair care routines to clients.

Written questions on the physical and chemical effects of chemical straightening and relaxing products on the hair's structure.

Evidence required for demonstration of consistent performance

For valid and reliable assessment of this unit, evidence should be gathered through a range of methods to indicate consistent performance.

It can be gathered from assessment of the unit of competency alone, through an integrated assessment activity or through a combination of both.

Evidence should be gathered as part of the learning process.
