Question: 1 / 400

What is a common sign of head lice infestation?

Intense itching

Intense itching is a common sign of head lice infestation due to the allergic reaction the scalp has to the bites of the lice. When lice feed on the scalp, they inject saliva, which can cause irritation and lead to a feeling of intense itching. This itching often motivates individuals to scratch their heads frequently, which can exacerbate irritation and result in secondary infections.

While a dry scalp, excessive hair shedding, and unusual hair color may be symptoms of other conditions or issues, they are not directly linked to head lice. It is primarily the intense itching that serves as a hallmark symptom of such infestations, making it the most recognizable indicator.
