Head lice, unlike fleas or ticks, exclusively adapt to human scalps as specialized parasites. They cannot survive on other animals, making us their exclusive hosts.

Contrary to common belief, lice do not discriminate based on hygiene. Anyone can get lice, regardless of how clean or dirty their hair is. These insects are more interested in blood than cleanliness, so personal hygiene has little to do with the likelihood of infestation.

Head lice spread through close human contact. They cannot jump or fly but are excellent at crawling. This means they are typically transmitted through activities like hugging, sharing combs or hats, also leaning in for a selfie.

Head lice have developed resistance to many common treatments. Overuse of certain chemical treatments has led to the evolution of “super lice” that are immune to pesticides. This has made lice infestations more challenging to manage. 온라인카지노
