4.2 Scalp & Skin Disorders and Contraindications

Quick Answer: Inspect the scalp, face, and neck before every service. Contagious disorders mean refuse service, clean and disinfect anything contacted, and refer the client to a physician. Non-contagious disorders often allow service with adapted technique. Barbers recognize what they see for safety—they do not diagnose medical disease or prescribe treatment. That recognition duty is core to Georgia’s public-protection approach under the State Board of Cosmetology and Barbers.

A haircut starts with eyes and gloves-ready judgment, not with the clippers. Contagious conditions can spread through combs, capes, towels, and direct contact. Serving a client with untreated ringworm or lice is not “being nice”—it is putting the next clients and the shop at risk and can support Board discipline for unsanitary practice.

Two Rules That Anchor Every Exam Item

1. Recognize, never diagnose. You may say, “I see scaling and broken hairs that look like a fungal infection; I cannot serve you today—please see a doctor.” You may not say, “You have tinea capitis; take this cream.”
2. When in doubt, refuse and refer. Unidentified lesions, open sores, pus, unexplained swelling, or anything that looks infectious is a stop sign until cleared medically.

Contagious Disorders — Refuse Service

Memorize the names, typical appearance, and the action: STOP.

Tinea is a fungal infection—not a bacterium and not “just dry scalp.” Pediculosis is an infestation with lice. Do not confuse loose dandruff flakes with nits: nits cement to the hair shaft and are harder to slide off than ordinary flakes.

Why “partial service” is still wrong

Exam traps often offer “cut only the unaffected side” or “style but don’t shampoo.” If the condition is contagious on the scalp or service area, refuse the service entirely. Partial contact still risks transmission to you and later clients.

Non-Contagious Disorders — Often Safe to Serve

These conditions are not spread client-to-client by normal barbering contact. You may usually proceed, with judgment:

Dandruff vs lice vs ringworm vs psoriasis — quick contrast

Clients often self-label everything as “dandruff.” Your job is visual triage: flakes alone with an otherwise healthy scalp usually allow service; patches with broken hairs, pustules, or live pests do not.

Facial and Neck Skin Considerations

Shaving and facial services add skin-risk layers:

• Pseudofolliculitis barbae (razor bumps) — often from curved hairs re-entering skin; not classic “ringworm,” but inflamed areas may need technique changes or temporary avoidance of close shaves.
• Open wounds, cold sores, or active bacterial infections on the service path — contraindication to shaving or waxing that area.
• Recent medical procedures or untreated infections — defer until the client has medical clearance.

Document what you observed and what you recommended (referral), especially for regular clients who return after treatment.

Georgia Public-Protection Framing

The Georgia State Board of Cosmetology and Barbers exists to protect the public. Infection-control chapters cover how to disinfect; this section covers when not to start. Key shop habits that support that duty:

• Visually inspect scalp and skin during consultation and draping.
• Never work over contagious lesions “as a favor.”
• After any contact with a suspected contagious condition, follow full cleaning and disinfection of implements, station, and linens—even if you refused the haircut.
• Do not reuse soiled neck strips, towels, or capes.
• Stay inside Barber II scope: you are not a dermatologist; referral is professional, not a failure.

Decision Flow You Can Memorize

1. Inspect hair, scalp, face, and neck.
2. Identify: clearly contagious → refuse + refer + disinfect.
3. Non-contagious but inflamed/oozing/unidentified → refer (and usually refuse until cleared).
4. Non-contagious and stable → serve, adapting products and pressure as needed.
5. Record notes when appropriate and welcome the client back after medical clearance.

Mastering this triage protects clients, protects your license, and scores reliably on Scientific Concepts and professional-practice items that test contraindications.
