California Cosmetology Written ExamClient Consultation and AnalysisMedium
A cosmetologist examines a client's scalp before a scheduled service and notices small, white, dry flakes scattered throughout the hair with an itchy but non-inflamed scalp. This condition is best identified as:
- APediculosis capitis
- BTinea capitis
- CPsoriasis
- DPityriasis capitis simplex (dandruff)
Show answer & explanationAnswer & explanation
Correct answer: D. Pityriasis capitis simplex (dandruff)
Pityriasis capitis simplex, commonly known as dry dandruff, presents as small, white, dry scales scattered on the scalp and hair with mild itching, and is not contagious, so the cosmetologist may proceed with service and recommend appropriate care.
Why the other options are wrong
- A. Pediculosis capitis (head lice) involves nits and live insects, not flaking.
- B. Tinea capitis is a contagious fungal infection causing bald patches and inflammation.
- C. Psoriasis produces thicker silvery-white scales on red patches, often with defined borders.
Pityriasis Capitis Simplex (Dandruff)
A common, non-contagious scalp condition characterized by small, white, dry scales and mild itching caused by excessive shedding of epidermal cells.
- Non-contagious, safe to service
- Small, dry white flakes
- Different from oily dandruff (pityriasis steatoides)
Memory trick: 'Simple and dry, flakes fly by' — simplex means dry dandruff.
