MYTH : My child does not have an itchy head so she couldn’t have head lice.
FACT : 80% of people with lice never have itching symptoms. The itching is caused by an allergic reaction to the louse bite. Much like mosquitoes head lice leave behind a residue of anticoagulant, anesthetic and saliva when they take a blood meal. Most people do not react to these substances, but a small percentage of people do develop an allergic itching symptom reaction after they have had lice for 2 months.
