Do people always itch when they have Head Lice? No, people do not always itch when they have Head Lice. Most people do not have itching for the first 3 months once they’ve contracted Head Lice. This makes sense from the Head Lice’s point of view. The Head Lice do not want their host to know that they are setting up a Lice colony on their their head, until the Lice colony is well populated, and has sent out other Lice to other hosts to create satellite colonies. Then 3 months into the original Head Lice colony, the host often has an allergic reaction, which causes the itching. The Head Lice leaves saliva, anticoagulant, and anesthetic when feeding on a human host. All of these substances can trigger an allergic reaction to the bits.
