Signs and Symptoms
The most common locations for head lice infestations include:
  • Scalp, especially the hairline near the neck
  • Behind the ears
  • Neck
Moving lice or non-moving nits may be seen on the scalp and hair. Each louse is approximately 1–2 mm long and is white-gray in color. The white nits are smaller (0.5 mm), are firmly attached to the hair shaft, and are usually located very close to the scalp. In longer-standing infestations, the nits may be farther away from the scalp. In addition, small, red bumps may be seen on the scalp, neck, and shoulders. If scratched aggressively, these bumps may become scabbed.

Occasionally, the lymph nodes behind the ears or in the neck may be swollen.

Head lice infestations are quite itchy.
