2. Common Hair Pests in Children

Children are particularly susceptible to certain hair pests due to their close contact with peers and shared environments. The most common pests include head lice, which are small, wingless insects about 2-3 mm in length that live on the scalp and feed on human blood. Lice eggs, or nits, are often found attached to hair shafts close to the scalp.

Another possibility is mites, such as the scabies mite, which is much smaller, measuring only about 0.2-0.4 mm. While scabies mites typically burrow into the skin, they can sometimes be found in hair. Understanding the characteristics of these pests can help in identifying the issue.
