A client presents with a persistent, itchy, red rash on their scalp, accompanied by silvery scales. The cosmetologist observes that the scales are thick and well-defined. What scalp condition does this most likely indicate?
- ADandruff (Pityriasis capitis simplex)
- BPsoriasis of the scalp
- CTinea capitis
- DSeborrheic dermatitis
Show answer & explanationAnswer & explanation
Correct answer: B. Psoriasis of the scalp
The symptoms described—persistent, itchy, red rash with thick, silvery scales—are characteristic of psoriasis of the scalp. Psoriasis is a chronic autoimmune condition that accelerates skin cell turnover, leading to these distinct plaques. Cosmetologists should recognize these signs and refer the client to a medical professional.
Why the other options are wrong
- A. Dandruff typically presents as small, white, flaky scales with mild itching, without the prominent redness or thick, silvery appearance of psoriasis.
- C. Tinea capitis (ringworm of the scalp) is a fungal infection that causes patchy hair loss, scaling, and inflammation, but the scales are not typically silvery and thick in the same manner as psoriasis.
- D. Seborrheic dermatitis involves greasy, yellowish scales and redness, often with inflammation, but the scales are not typically described as thick and silvery like psoriasis.
