Busting Myths about Head Lice!
- Hair color does not kill lice, it colors lice
- Boys do get lice. Even boys with very short hair or buzz cuts

- Lice are not living in your house and re-infesting your family…Lice can only live and reproduce on a human head. Off the head, adult lice die within 48 hours and they only lay nits (lice eggs) on a human head
- The over-the-counter pesticides and prescription treatments no longer work as the lice have grown fully resistant to the pesticides they contain. Product failure is part of the reason for the high level of lice outbreaks.

You did not have the right products, tools and instructions to truly get rid of lice

Which came first: the itchin’ or the egg…
A nit, the egg of the louse, is laid on the shaft of a hair. Nits that come off the hair are harmless and cannot infect a new person.
Day 7 – 10
Nits hatch 7-10 days from when they are laid. When a louse is first hatched it is called a nymph.
Day 9 – 20
The nymphs shed their outer shell (exoskeletal system) 3 times before the bug is an adult. The nymphs will very rarely leave their host’s head until mature & fertilized.
Day 17 – 20
A female adult only needs to be fertilized 1 time and is fertile for life.
Day 18 – 22
The female lays her 1st eggs 1-2 days after being fertilized. She can lay 3-5 eggs twice a day for the next 14-16 days. She can lie up to 200 eggs in her lifetime. If a fertilized louse moves onto a new head, the fertilized louse may thrive and lay nits almost immediately. She may not survive the blood type of the new host and die leaving behind a few hard to detect viable nits that will hatch to thrive on a new host.
Day 32 – 38
The louse dies having lived 32-38 days since being laid as a nit.
