Likely head louse egg (nit)

Attached firmly to human scalp hair, usually near the roots, where warmth supports development. The pictured object may be a detached or empty nit; identification is uncertain because no hair shaft is visible.

Adults and nymphs feed exclusively on small amounts of human blood by piercing the scalp.

Wingless lice crawl rather than jump or fly; females cement eggs to hair shafts, and eggs hatch in approximately 7–10 days. Transmission occurs mainly through direct head-to-head contact.

Head lice cause itching, irritation, and scratching-related skin infection but do not generally transmit serious disease. They provide no meaningful human benefit.
