Patch Testing for Mobile Hairdressers: Legal Requirement or Best Practice?

This is one of the most confidently-stated claims in the hairdressing industry — and one of the least clearly sourced. Our research found no specific regulation directly mandating patch testing for hairdressers. What we did find: it's commonly a manufacturer's instruction for colour/chemical products, it's frequently an express condition of insurance cover, and it's often the deciding factor in negligence claims when skipped. Several claimant-solicitor websites describe it as 'a legal requirement under Section 3 of the Health and Safety at Work etc. Act 1974' — but that specific legal interpretation (as opposed to patch testing being one way of meeting a general safety duty) could not be independently verified in our research. We think the honest, useful answer is: treat patch testing as essential risk management — for your client's safety, your insurance cover, and your legal protection — rather than stating with false confidence that a specific law requires it. Always follow your product manufacturer's current instructions and your insurer's policy terms, and keep dated patch-test records (our £49 Kit includes a combined Consultation, Consent & Patch Test Record template for this).
