What are recognizable signs of pediculosis capitis?

• A. Red patches on the scalp
• B. Small white spots that adhere to hair shaft
• C. Flaky white skin on the scalp
• D. Thinning of hair

Answer: (B)

Pediculosis capitis, commonly known as head lice infestation, is characterized by the presence of small white spots that adhere firmly to the hair shaft. These spots are actually the eggs, or nits, laid by the lice, and they can be mistaken for dandruff. Unlike dandruff, which can be easily brushed away, nits are attached to the hair and require specific treatments for removal. Recognizing nits is essential for diagnosis and treatment because they indicate an active infestation. Additionally, identifying these nits early can help prevent the spread of head lice to others. Other signs of pediculosis capitis may include itching or irritation of the scalp due to the insects feeding on the host's blood, but the presence of nits is a definitive indicator of this condition. While various symptoms such as red patches on the scalp, flaky white skin, and thinning of hair can occur, they are not the hallmark signs of lice infestation. The most direct and recognizable sign is indeed the small white spots that cling to the hair shaft, which helps differentiate pediculosis capitis from other scalp conditions.
