The Circular Scalp Patch and the Shared Clippers
It is 3:40 p.m. on a busy Saturday at a three-chair shop. A walk-in client, Marcus, 28, sits in your chair for a taper fade. While cutting, you notice a quarter-sized, circular, scaly patch on his left temple with broken hairs. He says it has been itchy for two weeks and he has been using a friend's clippers. You finish the cut with a #1 guard and clipper-over-comb. After he leaves, you see a small amount of blood on the blade from a nick behind his ear. The shop uses a spray bottle of 70% isopropyl alcohol for clippers, and the barbicide jar was last changed Tuesday. There are two more clients waiting, and the owner wants to close at 5. Another barber used the same clippers 20 minutes earlier on a 6-year-old.
1. What condition should you suspect, and what immediate actions should you take with Marcus and the clippers?

Suspect tinea capitis (scalp ringworm), a contagious fungal infection. The circular scaly patch, broken hairs, and itching are classic, but you cannot diagnose definitively. Stop the service, wash your hands, put on gloves, and avoid touching the lesion. Tell Marcus privately that the patch looks contagious and needs medical evaluation before another haircut. Do not treat it with shop products or cover it with powder. The clippers are now contaminated: remove the blade if removable, brush off hair, clean with soap and water, then disinfect with an EPA-registered hospital-grade disinfectant labeled tuberculocidal, following the label contact time. Alcohol spray is not adequate. Because there is blood on the blade, treat this as a bloodborne-pathogen exposure: wear gloves, dispose of the blade in a sharps container or disinfect it properly, clean and disinfect the clipper body, and complete an incident report. Notify the owner and review whether the 6-year-old's parent must be contacted based on the shop's exposure-control policy. Do not use those clippers on the waiting clients until disinfected.
2. Evaluate the shop's disinfection practices and describe the correct protocol for clippers, blades, and the barbicide jar.

Two practices are unacceptable. First, 70% isopropyl alcohol sprayed on clippers is not a hospital-grade disinfectant; it evaporates quickly and does not reliably kill fungi, bacteria, or bloodborne viruses on a contaminated blade. Second, a barbicide jar changed on Tuesday and used through Saturday is not being maintained: disinfectant solutions must be changed at least daily, or sooner if visibly soiled, and implements must be fully immersed for the label contact time. Correct protocol: wear gloves; remove the blade; brush off hair; wash with soap and water; dry; then either immerse removable blades in an EPA-registered disinfectant or spray/wipe the clipper with a product labeled for the organisms of concern. Porous items that cannot be disinfected must be discarded. Blood-contaminated items require the same clean-then-disinfect sequence, and single-use blades should be discarded in a sharps container. Keep a written log of solution changes and disinfection times, and use a clean cape and towel for each client.
3. What should you tell Marcus and document, and when may he return?
Read the worked answer
Tell Marcus that the patch looks like a contagious fungal infection and that he should see a physician or clinic before getting another haircut. Avoid saying 'you have ringworm' as a diagnosis; say 'this needs medical evaluation.' Advise him not to share clippers, combs, or hats, and to wash his hands. Document the date, the location and appearance of the lesion, that the service was stopped, the referral given, the equipment disinfection performed, and the incident report number. If your state requires reporting of certain communicable conditions, follow that rule. He may return only after a physician clears him or the lesion is no longer active and he has completed appropriate treatment. Do not allow him to book a haircut 'just to tidy up' while the patch is active.
