What are common signs of an infestation in hair?

1. Loss of hair and brittleness

2. Excessive itching and visible lice or eggs

3. Dullness and split ends

4. Increased oiliness

The correct answer is: Excessive itching and visible lice or eggs

Excessive itching and visible lice or eggs are significant indicators of a hair infestation, primarily associated with head lice. Lice are small parasites that feed on human blood and typically cause intense itching due to their saliva, which can lead to a rash. Additionally, the presence of visible lice or their eggs (nits) in the hair is a clear sign of infestation. Identifying these symptoms quickly is crucial for effective treatment, which often includes specific shampoos or treatments designed to eliminate the parasites. While the other options mention conditions that can also occur in hair, they are not specifically indicative of an infestation. Loss of hair and brittleness can occur for various reasons, including hormonal changes, stress, or nutritional deficiencies. Dullness and split ends often arise from physical damage or lack of proper care but are not related to lice. Increased oiliness can be a result of overactive sebaceous glands or poor hair hygiene, not an infestation. Therefore, the combination of excessive itching along with visible lice and eggs distinctly points to an infestation, making it the correct choice.
