Intense Itching
One of the first signs of a lice allergy is an intense itching sensation. This is due to the allergic reaction to lice saliva when they bite to feed on human blood. This can cause discomfort and often gets worse at night when lice are most active.
Red Bumps on Scalp
Experiencing red bumps or rashes on the scalp, neck, and shoulders can be a symptom of a lice allergy. These are typically caused by an allergic reaction to lice bites and can appear as small, pink or reddish bumps.
Swelling
Due to your body's immune response to the lice bite, you may experience swelling around the area of the bite. This is a common symptom of an allergy to lice.
Sleep Disturbances
Lice are most active during the night which can lead to sleep disturbances caused by discomfort and itching. This can often lead to fatigue and tiredness during daytime.
Irritability and Difficulty Concentrating
Constant itching and discomfort caused by lice can lead to irritability and difficulty concentrating. This is particularly common in children and can affect their performance at school.
Presence of Lice
A clear symptom of a lice allergy is the physical presence of lice on the head. They can be seen crawling on the hair, and their eggs, known as nits, can be found attached near the base of the hair shaft.
