Head lice have plagued humans for centuries, presenting a persistent hair-related problem. These bothersome insects have adapted to our society and are found exclusively among human populations. There are three types of lice that commonly affect people: body lice, pubic lice, and head lice. Among these, head lice pose the greatest threat as they have a rapid and efficient spreading mechanism.
Understanding Itchy Scalp and Head Lice
An itchy scalp is a prevalent symptom associated with head lice infestation. This symptom is often the first complaint among individuals affected by head lice. Contrary to popular belief, the itchiness is not caused by the lice themselves residing on the scalp; rather, it is a result of an allergic reaction triggered by louse saliva. Although itchiness is a common occurrence, it typically manifests a few weeks after the initial infestation. In some cases, however, individuals may not experience any itching at all, as they may not be allergic to the saliva.
Feeling of Movement
One of the most unpleasant symptoms associated with the presence of these unsettling insects is the sensation of something crawling on our scalp. This crawling feeling is particularly common among younger individuals. The lice and their movement on the scalp and surrounding area are responsible for this sensation. Similar to the previously mentioned symptom, this sign often occurs a few weeks after the initial infestation. Initially, the lice remain stationary and only start to move later on. If your child expresses discomfort due to a sensation of something on their head, they might be dealing with a lice infestation.
