Mould, poor hand-washing facilities and sub-par disinfecting are among a raft of issues discovered at Queenstown hair salons.
At another, chemicals were stored next to tea and coffee.
Council inspectors visited 22 salons in the Queenstown and Arrowtown areas in the past year to check if they were up to scratch.
Hair salons are required to meet health and hygiene standards under the Health (Hairdressers) Regulations 1980, and are inspected annually.
Inspection reports released to the Mountain Scene newspaper show two salons, Arrowtown Hair Company and Hair Trucco, were found to have mouldy walls or ceilings.
