10 Symptoms of Head Lice

7. Mood Swings

People with lice infestations are likely to be irritable, or they may seem unpleasant at times. This is because the long-term itchiness and irritation caused by lice also have a negative consequence on their emotional stability. Sleep deprivation is another factor that contributes to irritableness and can make going to work or school a difficult task. Concentration for extended periods of time is also likely to be difficult. One of the first signs parents notices about their child if they get an infection is a change in their mood. Coupled with an itchy scalp, the culprit is usually a lice infection.
