What Causes Head Lice?
When diving into the world of head lice, it's essential to understand the full picture. Asking ‘what causes head lice?’ is just the beginning. The cause of head lice is simple: they love our hair (and scalp)!
Contrary to belief, head lice are NOT caused by being unhygienic. While many believe that lice caused by or a sign of poor hygiene, that's just a lousy myth!
No matter how clean or dirty your hair is, head lice love it all the same. Surprised? Learn more about head lice and nits with our head lice fact sheets!
The real question to ask is, ‘how do head lice spread?’ It's a combination of our social behaviours and the lice's natural instincts. As they move from one head to another, they're not just looking for food (your blood); they're seeking the ideal environment to lay their eggs and continue their lifecycle (your hair).
While the way head lice spread varies somewhat, the outcome is usually the same: an itchy situation that requires immediate attention.
By understanding both the cause of head lice and their rapid spread, we're better equipped to prevent and treat these pesky invaders.
