SHBHREF002 — Straighten and relax hair with chemical treatments

Elements & performance criteria

Performance evidence

• Evidence of the ability to complete tasks outlined in elements and performance criteria of this unit in the context of the job role, and:
• consult with at least four clients, each with different hair straightening needs, and cumulatively complete these treatments which consistently achieve the planned degree of hair straightening or relaxation and without hair breakage:  chemical treatments on untreated natural curly or wavy hair  chemical treatments on chemically treated hair  chemical treatments on strong or resistant natural curls
• for each client, complete a pre-treatment hair analysis covering the following characteristics to recommend appropriate chemical straightening treatments:  hair and scalp condition  hair texture  hair density  hair porosity  degree of curl or wave  length of hair  effects on hair of previous chemical services
• record the following details of the chemical straightening service in the history for each client serviced:  pre-service hair analysis  contraindications  desired degree of relaxation  products, strengths and processing times used  straightening methods used  degree of relaxation achieved  recommended home care products

Knowledge evidence

•  key characteristics and interrelationships of the elements and principles of hair design and use in achieving hair straightening and relaxation effects;  elements of hair design:  line  shape  direction  size  texture  colour  principles of hair design:  balance  gradation  repetition  contrast  harmony  dominance  unity
•  hair biology, at an elementary level of understanding:  main functions and role of hair  main factors contributing to degree of curl or wave in hair  structure and cellular features of hair and hair follicles  process of hair growth and the hair growth cycle  characteristics of normal and damaged hair  physical effects of chemical products and treatments on the skin  main structure, functions and role of the skin and glands:  skin surface anatomy  major epidermal appendages and dermal structures  major cells of the epidermis  role of vascular, connective and nervous tissue in the dermis  distribution and development of skin glands  production, composition and functions of sebum  production, composition and functions of eccrine and apocrine sweat fluids
•  basic concepts of cosmetic chemistry, as they apply to effective and safe use of chemical straightening products:  bonds  molecules  chemical compounds  chemical change  neutralisation  acids and bases  pH
•  at an elementary level of understanding, the chemical and physical effects on hair structure and bonds, texture and curl or wave of:  protein fillers  chemical straightening and relaxing products  post-process conditioners  neutralisers  application of heat
•  key factors that influence degree of relaxation achieved:  hair porosity  hair condition  degree of initial curl or wave  product type and strength  processing time  environmental humidity  smoothing and re-bonding methods
•  contraindications to using chemical hair straightening products:  abnormal scalp conditions, including broken or weeping areas of skin  hair or scalp damage from previous chemical hair treatments  highly porous hair  resistant hair
•  organisation’s chemical hair straightening products range:  strengths and formulation  product purpose  action on the hair  application instructions  processing times
•  role and basic content of Safety Data Sheets (SDS) or plain English workplace documents or diagrams that interpret SDS content
•  basic aspects of local government, state or territory health regulations applicable to providing chemical hair reformation services
•  industry practices and organisational procedures for:  client comfort and safety with particular emphasis on:  using gown and towels to protect client clothes  application of barrier creams to face and neckline  avoiding product contact with eyes  avoiding hair breakage by application 1cm from hair root  monitoring client scalp comfort and condition  work health and safety for providing chemical hair straightening treatments, with particular emphasis on:  avoiding product contact with operator eyes and skin  avoiding inhalation of fumes during product preparation and application  using correct posture and adjusting height of client chair to avoid fatigue and injury  using correct techniques to hold, grip and manipulate hair reformation tools to avoid fatigue and injury  minimising wastage of chemical straightening products  water efficiency  waste disposal with particular emphasis on environmentally sound disposal methods for hazardous and other hairdressing waste.

Foundation skills

• Reading skills: interpret sometimes unfamiliar and detailed documents including organisational procedures, product instructions and safety data sheets.
• Oral communication skills: ask open and closed probe questions and actively listen to effectively interact with client and meet their needs.
• Numeracy skills: calculate and record strengths, measure and apply correct amounts of reformation chemicals and neutralisers; manage application and processing times effectively.
• Planning and organising skills: manage own timing and productivity to complete reformation treatment services within organisational service times.
