Cert III Hairdressing cheat sheet
Cert III Hairdressing · Keep the key ideas within reach.
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.
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.
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.
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.
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.
