Description
This unit describes the performance outcomes, skills and knowledge required to design and perform chemical curling and volumising services to add curl or body to short or medium length hair.
Notes
Elements and Performance Criteria
1. Assess hair and consult with client.
- 1.1. Complete preservice hair analysis and enter on client history.
- 1.2. Identify contraindications to chemical reformation and inform client, according to salon policy.
- 1.3. Discuss and confirm client expectations, finished hair design and desired degree of curl or body.
2. Select and apply reforming products and equipment.
- 2.1. Take personal precautions to prevent operator skin reactions to reformation chemicals.
- 2.2. Select chemical reformation products and rod sizes to match hair analysis and desired degree of curl or body.

- 2.4. Ensure client comfort and safety at all stages of winding, processing and neutralising, according to product instructions, safety data and salon procedures.
- 2.5. Cleanly section and wind hair with even lift, in a simple directional pattern, without hooked ends.
- 2.6. Secure rods to avoid breakage, rubber marks or drag.
- 2.7. Process hair and check at regular intervals to achieve predetermined degree of curl or body.
- 2.8. Follow salon procedures to minimise water and product waste throughout the service.
3. Rinse and neutralise hair.
- 3.1. Rinse hair thoroughly and evenly using tepid water to remove residual perm solution.
- 3.2. Evenly blot excess water from hair, according to product instructions.
- 3.3. Select neutralising products to match reformation chemicals.
- 3.4. Measure, apply and process neutralising products, according to product instructions and so as not to disturb hair on rods.
- 3.5. Gently remove rods in a manner that does not apply undue stretch to the newly reformed hair.
- 3.6. Remove residual neutralising chemicals from the hair, according to product instructions after the specified processing time.
- 3.7. Apply conditioning products after neutralising, according to product instructions.
4. Review the service and provide home care advice.
- 4.1. Review outcomes of service against established client expectations and confirm client satisfaction.

Evidence of the following is essential:
accurate preservice hair and scalp analysis
selection and safe application of products, equipment and techniques appropriate to desired outcomes and predetermined designs
interpreting and following product instructions and safety data
winding to a preplanned pattern with even tension and without hooked ends
securing rods to avoid breakage, rubber marks or drag

performing the full rinse and neutralising service.
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
fully equipped workstation which includes as minimum:
an adjustable client chair
clean client gown or wrap
a plentiful supply of clean towels
a trolley stocked with:
various sizes of perm rods
perm papers
rubber gloves
barrier creams
cotton wool
plastic bowls or applicator bottles
cap or plastic film wrap
fully equipped basin services area which includes as a minimum:
shampoo basins
client shampoo chairs
adjustable water temperature and shampoo spray attachments
a plentiful supply of clean towels
clean client gown
a professional range of chemical reformation products suited to hair analysis outcomes across a range of clients
access to relevant documentation, including:

product safety data sheets
salon procedures
a range of clients seeking chemical curling and or volumising services.
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:
direct observation of the learner:
conducting preservice hair and scalp analysis
confirming client expectations and advising on degree of curl and finished hair designs
selecting products and equipment
winding to a preplanned pattern with even tension and without hooked ends, breakage or rubber marks
consistently and successfully assessing the development of degree of curl for desired curl or body
performing the full rinse and neutralising service
applying safe work practices and product instructions.
written or verbal questions appropriate to the language and literacy level of the learner to test knowledge which include:
the effects of products used in chemical reformation on the structure and condition of the hair
personal precautions
client safety
salon waste minimisation procedures
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
SIRXOHS201A Apply salon safety procedures
