如果您开始发痒，那么您可能会担心头虱。

虱子在他们生命周期的每个阶段的样子
For those who don’t already know, lice is the plural form of louse (some people think they’re entirely different things).
虱子是一种小的，流血的寄生虫，生活在人类的头皮上，以人为食。每个虱子大约是一个大小单芝麻从白色到棕褐色到灰色的颜色范围。
When trying to figure out what your lice looks like, remember that there are 3 stages a louse will undergo and they all look different: Nits, Nymphs, and Adult.
尼特：NIT是虱子鸡蛋的另一个术语。尼特是大约结的大小in a strand of hair and are difficult to see. They latch onto hair follicles and can be difficult to remove without proper treatment.
若虫：Nymphs are the next stage of than adults and look like smaller versions of a full-grown louse. They range from 1-2 mm in length, which is smaller than the size of the tip of your pencil.
成人虱子：Lice have six legs with feet like hooks that grip onto single strands of hair. Their “hook grip” allows them to move through your hair easily.
看看以下视频，以了解它们如何移动以及要寻找什么。
虱子活多久？
Thankfully, lice have short lifespans.
成年虱子只活着roughly a month，或30天，在人头上。如果虱子掉下来或以某种方式去除，那么它们只能距离头皮持续1-2天。尼特大约需要8-9天的时间才能孵化，直到虱子出现后才有问题。
Lice Reproduction
虱子迅速繁殖，并有很多年轻人。每个雌性虱子都可以50-150傻瓜在他们lifetime. This means that a single pair of lice can have 150 children, which can then reproduce as well. Nits are attached to hair using a special, sticky, glue-like substance and are roughly only1/4 inch away从头皮。
How To Tell If You Have Lice
It should be pretty easy to tell if you or a loved one have a lice infestation. Below are some of the最常见的迹象that a lice problem exists.
- You can see movement from the lice on your head.
- 您开始患有发痒的头皮，头皮屑或在头发下干血。
- 使用放大镜，您可以看到头发中的虱子。
- 您在枕头或刷子上发现尼特。
The only way to truly tell if someone has lice is to see the infestation. If you have trouble identifying lice, use a magnifying glass.
You should be able to see small, six-legged bugs moving around close to the scalp. If you have an itchy scalp and flaking without seeing any pests, you might just havedry skinand should consider a dandruff shampoo.
