Scaly Patches and a Request for a Chemical Straightener
At 9:40 a.m., a 27-year-old woman with tightly coiled hair sits down for a relaxer and permanent color. She says her scalp has itched for two weeks and that she has been scratching “scabs” at her hairline. Under the shop's bright light, you see three quarter-sized patches of gray-white scale on the crown and nape. The hair inside the patches is broken close to the scalp, and you can see dark dots at the follicles. The surrounding scalp is red and slightly warm. She has a small open scratch behind her right ear from a comb. She says a friend told her to use a medicated shampoo, and she wants you to “just avoid the spots” with the relaxer. She has an appointment in 45 minutes and brought a photo of a sleek bob. The shop has no physician referral list. She denies fever but says the area feels tender. She has never had this before.
1. What is your working impression of the scalp condition, and what features make you consider tinea capitis rather than ordinary dandruff? Why can't you diagnose?

My working impression is that this needs medical evaluation and should be treated as potentially contagious until cleared. The features that raise concern for tinea capitis are the distinct scaly patches, broken hairs close to the scalp, and dark dots at the follicles, which can represent broken infected hairs. The redness, warmth, tenderness, and new onset also argue against simple dandruff.
Ordinary seborrheic dermatitis usually shows diffuse, greasy scaling, often at the hairline and eyebrows, without discrete patches of broken hairs. Psoriasis can cause thick silvery plaques and redness, but it does not usually cause the black-dot broken hairs described here. Those comparisons help me decide to refer, not to name the disease.
I cannot diagnose because barbering scope of practice does not include medical diagnosis, and a prescription antifungal or other medical treatment requires a physician. Telling the client “it's just dandruff” could delay treatment and expose other clients through shared tools. The correct judgment is to stop the chemical service, avoid giving a medical label, and refer.
2. Can you proceed with the relaxer and color if you avoid the patches? Explain the risks and your decision.

No. “Just avoiding the spots” is not safe. Relaxers are highly alkaline and break disulfide bonds in the hair; on compromised scalp they can cause chemical burns, increased absorption, and severe irritation. The open scratch behind the ear is a break in the skin, and the scaly, red, tender areas are already inflamed. Applying color on top adds another chemical insult, and the rinse water can carry product across the patches anyway.
There is also an infection-control problem. If the scalp has a fungal infection, scales and broken hairs can contaminate combs, capes, and the chair. A patch test for color does not rule out infection, and it does not make a compromised scalp safe for a relaxer. The client's 45-minute appointment and the photo do not change the risk.
My decision is to decline the relaxer and color today, explain the specific reasons in plain language, and offer to rebook after a physician has evaluated the scalp and cleared her for chemical services. I would not recommend a specific medicated shampoo; that is a medical decision. I would document the refusal and the referral.
3. What service, if any, can you provide today, and what sanitation and referral steps do you take?
Read the worked answer
I would not provide a chemical service today. If the client wants a haircut, I can provide a limited service with strict precautions: use a fresh cape and neck strip, keep my hands washed, avoid sharing combs, and place all tools used on the scalp in the cleaning and disinfection process afterward. I would avoid vigorous shampooing or scalp massage because it can spread scales and irritate the area.
I would refer her to a physician or clinic for evaluation of the patches, especially because the condition is new, tender, and associated with broken hairs. Since the shop has no referral list, I would tell her to contact her primary care provider or a local clinic and would not try to diagnose or prescribe. I would explain that she should not scratch the area and should not apply a relaxer until cleared.
Sanitation steps include laundering the cape and towels, disinfecting the chair and any tools that contacted the scalp, and washing my hands before and after. I would document the visible condition, the services declined, the referral, and the cleaning performed. This protects the client and the next client and keeps the decision within barbering scope.
