Hair Lice Symptoms. No itching. Most people don’t experience itching symptoms when they have Head Lice. This is yet another urban myth about 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.
Hair Lice Symptoms. No Health Problems. In fact head lice don’t cause any health problems at all. The worst part about head lice is the social stigma that drives people crazy. In fact even the CDC says kids should be kept in school when they have head lice
