NIC Cosmetology Written (Theory) ExamScientific ConceptsMedium

A cosmetologist is conducting a client consultation for a hair coloring service. The client mentions they have a recurring condition characterized by dry, silvery scales that appear on their scalp, sometimes with redness and itching, but it is not contagious. Based on this description, the client likely has:

  1. APsoriasis of the Scalp
  2. BTinea Capitis
  3. CPediculosis Capitis
  4. DSeborrheic Dermatitis
Show answer & explanation

Correct answer: A. Psoriasis of the Scalp

Psoriasis of the scalp is a chronic autoimmune condition characterized by thick, silvery scales, redness, and itching. It is not contagious.

Why the other options are wrong

  • B. Tinea capitis is a fungal infection (ringworm) of the scalp, which is highly contagious and typically presents with patchy hair loss and scaling, but usually not silvery scales.
  • C. Pediculosis capitis (head lice) involves intense itching and visible nits/lice, not silvery scales.
  • D. Seborrheic dermatitis (dandruff) presents with oily, yellowish scales and redness, often with itching, but not typically silvery scales or as thick as psoriasis.

Psoriasis of the Scalp

A chronic autoimmune skin condition affecting the scalp, characterized by well-defined patches of red skin covered with silvery scales.

  • Symptoms include thick, silvery scales, redness, and itching.
  • It is not contagious.
  • Cosmetologists should avoid irritating the affected areas and refer clients to a dermatologist.

Memory trick: Silvery scales? 'P' for Psoriasis, 'P' for Patches, 'P' for Persistent.
