Client consultation & patch testing Risk Assessment Template

Typical hazards & measures

• Emergency response to severe reaction — Keep a first-aid kit, cold compresses and clear escalation steps. Train staff to recognise angioedema, breathing difficulty or widespread hives; stop testing, call emergency services, record events, notify insurer if required, and review before resuming.
• Product mismatch between test and service — Test the exact brand, shade and oxidant strength to be used. Log batch/formula; re-test after any component change, time-limit expiry, or illness/pregnancy. Avoid day-of substitution unless an equivalent has been separately patch tested and recorded.
• Irritant dermatitis at test site — Check for cuts, eczema or sunburn; choose a low-friction site. Use the smallest quantity, avoid occlusion unless required, remove at the stated time, cleanse gently, and give clear guidance on washing, rubbing avoidance, and when to report persistent soreness or itch.
• Aerosol exposure during hair colour testing — In open-plan areas, mix persulphate powders with low-dust techniques, use scoop-to-bowl methods, avoid vigorous shaking, and mix under extraction where fitted. Position clients upwind of prep points and wipe surfaces to remove residues promptly.
• Medication masking or amplifying reactions — Screen for antihistamines, corticosteroids, immunosuppressants, isotretinoin and photosensitisers. Adjust timing, select alternatives, or defer where responses may be altered; seek clinician advice for complex cases and document the discussion before proceeding.
