Can I have head lice if I dont itch?

Absolutely! One of the most common assumptions which I hear is that, if an individual does not itch, then they surely do not have head lice. This is incorrect. Feeling itchy is an allergic reaction to the saliva of a louse. Although most people do develop a sensitivity to their saliva, for some, it may take as long as 4-6 weeks before a reaction occurs while for others, it may never develop. If a household member is diagnosed with head lice, it is important to check the rest of the individuals who reside in the same home, regardless of whether they itch or not. By skipping this step, the likelihood of spreading lice within the household members remains.
