What are the signs that you have lice? - in detail
Lice infestations become apparent through several observable indicators. Recognizing these signs early prevents spread and facilitates effective treatment.
- Persistent itching on the scalp, neck, or ears. The discomfort results from an allergic reaction to lice saliva and typically worsens several hours after a feeding session.
- Presence of live lice. Adult specimens are tan‑brown, about the size of a sesame seed, and move quickly across hair shafts. They may be seen crawling or clinging near the scalp.
- Nits attached to hair shafts. These oval, white or yellowish eggs are cemented to the strand close to the scalp, usually within ¼ inch of the root. Nits that are firmly stuck and do not slide off when the hair is gently brushed are a reliable indicator.
- Small, reddish‑brown bite marks. Repeated feeding can leave pinpoint lesions that may bleed slightly if scratched.
- Irritability or difficulty concentrating, especially in children, often results from the constant itching and discomfort.
A thorough examination involves parting the hair in sections, using a fine‑toothed comb on damp hair, and inspecting the scalp under adequate lighting. Detecting any combination of the above symptoms confirms the presence of a lice problem and warrants immediate remedial action.
