Quick reference

Work Health and Safety

  • WHS duty of care: employer must provide safe workplace, training and PPE; worker must follow procedures and report hazards.

  • Hazard hierarchy of control order: eliminate, substitute, isolate, engineer, administrate, then PPE last.

  • Chemical spills: contain with absorbent, ventilate, avoid water on acid spills, dispose per safety data sheet (SDS).

  • SDS must be accessible for every hazardous product; Section 2 lists hazards, Section 4 first aid, Section 8 PPE.

  • Electrical: test-and-tag portable equipment, RCD protection on circuits, no water near power points, report frayed cords.

  • Manual handling: keep load close, bend knees, avoid twisting, team-lift heavy stock, height-adjustable basin chairs.

  • Emergency: know fire exits, extinguisher types (CO2 for electrical), first-aid kit location, emergency numbers.

  • Incident reporting: record in register, notify regulator for serious incidents, worker consultation on WHS changes.

Hygiene and Infection Control in the Salon

  • Sterilisation kills all microorganisms; disinfection reduces pathogens but may not kill spores; sanitising lowers count.

  • Tools contacting broken skin or blood require sterilisation (autoclave or hospital-grade chemical); single-use items discarded.

  • Standard precautions apply to all clients: treat all blood and body fluids as infectious regardless of appearance.

  • Hand washing: wet, soap, scrub 20 seconds including wrists and between fingers, rinse, dry with disposable towel.

  • Capes, towels and gowns laundered after each client at minimum 60°C; soiled linen bagged separately.

  • Clippers and scissors disinfected between clients; blades oiled after immersion; combs cleaned of hair first.

  • Blood exposure: wear gloves, clean wound, cover, disinfect tools and surfaces, document and seek medical advice.

  • Salon surfaces: workstations, basins and trolleys cleaned at end of each service; waste bins lidded and emptied daily.

Quick reference

Client Consultation, Communication and Service Planning

  • Consultation sequence: greet, gather personal details, discuss hair history, analyse hair and scalp, agree plan, confirm cost, record.

  • Hair analysis factors: density, texture, porosity, elasticity, condition, scalp type, previous chemical services.

  • Patch test required 48 hours before colour or lightener on new clients; record result and date on client card.

  • Contraindications: open wounds, scalp infection, recent chemical burn, known allergy, pregnancy caution for some chemicals.

  • Communication: open questions, active listening, paraphrasing to confirm understanding, avoid jargon, check consent.

  • Service plan records desired outcome, products, timings, developer strengths, cost, aftercare and review date.

  • Cross-infection risk questions: recent head lice, ringworm, cold sores, skin conditions - defer service if infectious.

  • Client records kept confidential; disclose only with consent or legal requirement.

Shampooing, Conditioning and Scalp and Hair Treatments

  • Water temperature 37-40°C; too hot strips oils and aggravates scalp; too cold reduces cleansing.

  • Shampoo selection: clarifying for buildup, moisturising for dry hair, medicated for dandruff, sulphate-free for coloured hair.

  • Massage movements: effleurage, petrissage, tapotement; avoid vigorous massage on inflamed or broken scalp.

  • Conditioner applied mid-lengths to ends, avoiding scalp; rinse thoroughly to prevent buildup and limpness.

  • Deep treatment timing follows manufacturer instructions; heat cap increases penetration; rinse cool to close cuticle.

  • Scalp treatments: identify dry, oily, dandruff or sensitive scalp; medicated products require manufacturer contact time.

  • Towel dry by blotting and pressing, not rubbing, to reduce friction and cuticle damage.

  • Contraindications: recent chemical burn, ringworm, lice, open lesions - refer to medical professional.

Hair Cutting and Shaping (Including Men's and Women's Styles)

  • Cutting angles: 0° one length, 45° graduated, 90° uniform layer, 180° long layer; elevation determines shape.

  • Tension control: consistent sectioning and even tension prevent uneven lines; check balance across both sides.

  • Sectioning: centre part, horizontal and vertical sections, subsection width no wider than blade length.

  • Blunt cut creates weight line; point cutting softens; notching and slithering reduce bulk; texturising adds movement.

  • Men's cutting: clipper-over-comb for blending, taper at nape, guideline set then work upward and across.

  • Scissor-over-comb and freehand clipper work require guard lengths; check against client's desired length.

  • Cross-checking: comb hair in opposite direction to reveal missed lengths before finishing.

  • Dry cutting and point cutting on dry hair allow visual checking of shape and weight distribution.

Quick reference

Hair Colouring and Lightening

  • Colour wheel: opposite colours neutralise; blue cancels orange, violet cancels yellow, green cancels red.

  • Developer strengths: 10 vol (3%) deposit, 20 vol (6%) deposit/one level lift, 30 vol (9%) two-three levels, 40 vol (12%) maximum lift.

  • Natural level 1-10 scale; underlying pigment at each level: level 1 red-brown, level 5 red-orange, level 7 orange, level 9 yellow.

  • Patch test 48 hours before service; strand test for unknown hair history or high-lift work.

  • Lightening: apply to mid-lengths and ends first, roots last due to heat; do not exceed manufacturer processing time.

  • Toning after lightening uses low-volume developer to deposit and neutralise unwanted warmth.

  • Grey coverage: use natural series, allow 100% grey formula; resistant grey may need pre-softening.

  • Strand test and record formula: brand, shade, developer, ratio, timing, result - essential for repeat services.

Quick reference

Chemical Waving and Straightening

  • Perm process: pre-test, wind, saturate with waving lotion, process, rinse, blot, neutralise, rinse, condition.

  • Winding tension and rod size determine curl: smaller rods tighter curl, larger rods looser wave; even tension prevents spotting.

  • Processing time depends on hair porosity and product strength; check curl development every few minutes.

  • Neutraliser rebuilds disulfide bonds; must fully saturate each rod and remain per manufacturer time.

  • Relaxers and straighteners: base scalp, apply to new growth first, avoid overlapping, do not exceed timing.

  • Contraindications: hair with metallic salts, recent bleach, damaged or broken hair, scalp abrasions.

  • Strand test and patch test mandatory; record product, strength, timing and result.

  • Aftercare: wait 48-72 hours before shampooing, use sulphate-free products, avoid heat styling immediately.

Hair Styling, Blow Drying and Finishing

  • Blow-drying: rough dry to 80% then section and direct airflow from root to tip to smooth cuticle.

  • Nozzle concentrates airflow for smoothing; diffuser disperses heat for curls and reduces frizz.

  • Heat protection products reduce thermal damage; keep dryer moving to prevent hot spots and burns.

  • Styling products: mousse for volume, gel for hold, wax for texture, serum for shine, hairspray for finish.

  • Setting techniques: rollers for volume and curl, pin curls for soft waves, hot tools for defined curl.

  • Up-styling: section, backcomb for volume, secure with pins, balance shape against face shape.

  • Finishing check: balance, symmetry, client satisfaction, product recommendation and photograph with consent.

  • Clean tools and sanitise hot tools between clients; check cords and heat settings before use.

Salon Operations, Sustainability and Product Knowledge

  • Stock control: rotate stock, check expiry dates, record usage, reorder at minimum levels; store chemicals away from heat.

  • Product dilution and ratio accuracy affect results and safety; measure with supplied scoops or scales, never estimate.

  • Sustainability: refill and bulk purchase, recycle packaging, reduce water and energy use, dispose chemicals correctly.

  • Waste segregation: chemical waste, general waste and recycling separated; never pour chemicals down drains.

  • Retail sales: recommend based on hair analysis, explain benefits, record purchase for follow-up.

  • Appointment scheduling: allow processing time, buffer for consultation, record client preferences.

  • Financial basics: service cost includes product, time, overheads and profit margin.

  • Equipment maintenance: clean and service tools, replace blades and cords when worn, log maintenance.

Quick reference

Teamwork, Professional Practice and Industry Knowledge

  • Professional boundaries: maintain confidentiality, avoid personal social media contact, respect client autonomy.

  • Team communication: handover notes, clear task allocation, respectful feedback, escalate concerns to supervisor.

  • Industry bodies and regulation: state/territory health regulations, fair trading, privacy principles, code of conduct.

  • Continuing professional development: attend training, update skills, follow new product information and SDS.

  • Grievance and complaint handling: listen, acknowledge, investigate, resolve and record outcome.

  • Scope of practice: refer medical scalp conditions, allergic reactions and complex colour corrections to qualified professionals.

  • Client confidentiality: store records securely, share only with consent, retain per legal requirements.

  • Workplace rights: fair pay, safe conditions, no discrimination or harassment, right to refuse unsafe work.
