What condition results from an infestation of the hair and scalp with head lice?

1. Pediculosis capitis

2. Alopecia

3. Scalp dermatitis

4. Folliculitis

The correct answer is: Pediculosis capitis

The condition that results from an infestation of the hair and scalp with head lice is known as Pediculosis capitis. This medical term specifically refers to the presence of lice on the scalp and hair. Head lice are small parasitic insects that live on the human scalp, feeding on blood and causing itching and irritation. Identifying this condition is essential for effective treatment since it involves specific interventions to eliminate the lice and their eggs. Pediculosis capitis manifests with symptoms such as itching and discomfort, and it often requires the use of medicated shampoos or topical treatments to eradicate the infestation. Other conditions listed do not pertain to head lice specifically. Alopecia refers to hair loss, which is unrelated to lice. Scalp dermatitis encompasses a variety of inflammatory conditions of the scalp, such as dandruff or seborrheic dermatitis, which have different causes and treatments. Folliculitis is an infection or inflammation of the hair follicles, usually caused by bacteria or fungi, rather than by parasitic infestation. Understanding these distinctions is crucial for anyone studying hair and scalp health.
