Head Lice and Nits

What are Lice?

Lice are parasites usually found in the scalp. Outside the scalp, they die between 24 to 48 hours. Their favorite food is the blood he feeds on, four times a day. What a vampire!

The lice lodges itself at the back of the neck and behind the ears because it runs away from  light and seeks the warmth of the human body. They love clean, curly, straight, blond, dark hair ... and they don't understand social status. All that matters is feeding and breeding in record time.

Who can catch lice?

Head lice infestation known as pediculosis is more common in children aged 3 to 11 who attend school but anyone is prone to catching them.

  • Itching caused by lice bites.

  • Irritability and difficulty sleeping as lice are most active at night.

  • Scalp lesions caused by scratching. These lesions can become infected.

Curiosities about Lice

 

A louse passing from one head to another and feeding on a new blood type can die instantly , however if it lays eggs before it dies, the new eggs can feed on the new blood type and survive;

 

Lice can only move to a new head 5 days after hatching and can start laying eggs 7 to 10 days after hatching. If you find a baby louse a few days after treatment, it means that some nits were left behind;

 

A female louse can mate once and become pregnant for life, laying 4 to 5 eggs twice a day for about 20 to 23 days before dying. This way we can see how quickly a lice infestation can happen.
