California Cosmetology Written ExamClient Consultation and AnalysisMedium
A cosmetologist examines a client's scalp before a color service and notices redness with thick, oily, yellowish scales along the hairline and eyebrows. This is most consistent with which condition, and what should the cosmetologist do?
- ASeborrheic dermatitis; refer the client to a physician before performing a chemical service
- BAlopecia areata; apply a strengthening scalp treatment
- CTinea capitis; refuse service and disinfect all tools immediately
- DPityriasis capitis simplex; proceed with the service as normal
Show answer & explanationAnswer & explanation
Correct answer: A. Seborrheic dermatitis; refer the client to a physician before performing a chemical service
Seborrheic dermatitis presents as redness with thick, oily, yellowish scaling, often around the hairline, eyebrows, and other oily areas. Because it involves inflamed, irritated skin, the client should be referred to a physician before undergoing chemical services that could further irritate the scalp.
Why the other options are wrong
- B. Alopecia areata causes smooth bald patches, not scaling or redness.
- C. Tinea capitis presents with circular bald patches and broken hair, not oily yellow scaling.
- D. Simple dandruff produces dry, white flakes without inflammation or oily yellow scales.
Seborrheic Dermatitis
Seborrheic dermatitis is an inflammatory skin condition causing redness and thick, oily, yellowish scales, often on the scalp, eyebrows, and hairline.
- Caused by overactive sebaceous glands
- Distinct from dry dandruff (pityriasis)
- Refer to a physician before chemical services if inflamed
Memory trick: Seborrheic = 'Sebum-heavy' — greasy yellow flakes, not dry white ones.
