Head Lice Treatment – Understanding Life Cycle of the Louse

nits and lice life cycle

Let me share a famous quote first:

“Know Your Enemies… Before You Eradicate Them”

Ok it’s not so famous because I just wrote it.

However, the point is… You must know what problem you are facing before you look for a solution.

Here it’s obvious that either you have head lice or someone close to you has got some in their hair. So, before we move on to discuss how you can get rid of them with proper head lice treatment, let me briefly tell you about them as well as their life cycle.

About Head Lice and their Residence

Head lice are parasitic insects and to discover whether they reside in someone’s hair or not, look for them behind the ears or near the neckline.

Who May Not Need Head Lice Treatment

It’s been observed that head lice prefer a specific hair shape for infestation. They are very, very uncommon in African Americans probably due to their specific hair shape.

Are Head Lice Dangerous? Should You Go for Head Lice Treatment Immediately?

Head lice are not hazardous and you can’t get any disease from them. So, there is no need to feel worried or rush for head lice treatment. Yes, they can disturb you psychologically and make you itch, but they are not dangerous.

Life Cycle of the Louse

Let’s now talk about their life cycle. Head Louse has three stages:

  1. Nit
  2. Nymph
  3. Adult

From ‘egg’ to ‘death’ the life cycle of a head louse is about 30 days.

1. Nits

Nits are the eggs of head lice. They are firmly attached to human hair after they are laid by an adult female louse. You can find them near the scalp (within 6 mm to be precise) because they require body heat to survive. The shape of nits is oval and the size is 0.8mm by 0.3mm. They take around 6 to 9 days to hatch. One important point to note is that after head lice treatment, you may get rid of head lice, but dead eggs may remain attached. So, once the head lice treatment is done you have to get rid of nits as well. We will talk about getting rid of nits after head lice treatment in detail later.



2. Nymphs

After an egg hatches, a nymph is released. However, the nit remains attached to the hair. They nymph actually looks like an adult louse, but it is a bit smaller in size. All nymphs have different sizes. However, they are almost as big as a pinhead. You can find them near the scalp and behind the ears or near the neckline. It takes nymphs about 7 days or more to become adults.



3. Adult

Adult lice suck human blood to live and survive. They feed about 5 times a day. They can travel quickly and are really active. They are about as big as a pin head. However, the female lice are larger in size than the male lice. When it comes to reproduction, a female louse can lay up to 8 eggs or nits per day. You can find them near the scalp and behind the ears or near the neckline. They live for 30 days on a person’s head.



Now you know about the life cycle of head louse. When you start head lice treatment now, you will know what you are dealing with.
