California Cosmetology Written ExamSafety and Infection ControlHard
A cosmetologist notices small white nits attached to a client's hair shafts near the scalp and observes live insects moving through the hair. What is the appropriate action under California health and safety rules?
- ADisinfect the shears for double the normal contact time and proceed
- BRefuse service until the infestation has been treated and resolved
- CProceed with the haircut but avoid touching the scalp directly
- DApply an over-the-counter pediculicide shampoo in the salon before starting
Show answer & explanationAnswer & explanation
Correct answer: B. Refuse service until the infestation has been treated and resolved
Pediculosis (head lice) is a contagious parasitic infestation. Cosmetologists must refuse service until the condition is treated and resolved, since continuing risks spreading the infestation and cosmetologists are not licensed to treat it medically.
Why the other options are wrong
- A. Longer disinfection of tools does not address a live infestation on the client.
- C. Avoiding scalp contact does not prevent transmission via hair and tools.
- D. Administering treatment is outside a cosmetologist's scope of practice.
Pediculosis Refusal
Pediculosis (head lice) is a contagious parasitic infestation identified by nits or live lice; service must be refused until it is resolved to prevent spread.
- Highly contagious via hair/tool contact
- Cosmetologists cannot treat medical infestations
- Service refusal protects other clients and staff
Memory trick: 'Nits in sight, no service tonight.'
